Compare Axial vs Centrifugal Blowers

Need Better Airflow in Your Commercial Space. Find the Right Extractor Fan Here

Axial fans utilize a propeller-like blade assembly to draw air along a straight path, parallel to the shaft. They provide high flow rates at relatively low static pressure. Axial models work well for low-resistance applications like air curtains, cooling towers, spot cooling and fume exhaust.

Centrifugal blowers use an impeller wheel that spins air radially from the blade tips. The swirling action generates higher pressure to overcome ductwork resistance. Centrifugal fans are commonly used for HVAC, ventilation and fume extraction in commercial settings.

Noise Levels

Centrifugal blowers typically operate more quietly than axial fans. The forward-curved blades slice smoothly through the air at an efficient angle. Axial fans can be noisier, especially at higher speeds, due to choppy air movement.

Motor Position

In axial fans, the motor sits parallel to the airflow, often exposed directly in the airstream. This requires special washdown-duty motors for wet or corrosive environments. In centrifugal blowers, the motor sits perpendicular to airflow, isolated from the airstream.

Efficiency and Pressure

Need Better Airflow in Your Commercial Space. Find the Right Extractor Fan Here

Centrifugal fans generate higher pressure, using a spinning impeller to compress air molecules. The swirling action overcomes static pressure in ductwork. Axial models move air in a straight line, better suited for low-resistance areas.

Maintenance

The forward-curved blades in centrifugal blowers are self-cleaning due to smooth airflow. Axial designs see high particulates that require cleaning. Centrifugal wheels are statically and dynamically balanced for smooth operation with less wear.

Hazardous Environments

For hazardous locations, centrifugal blowers limit sparks and heat generation that could ignite flammable gases, vapors or dusts. Axial fans often require special materials and designs to be explosion-proof.

Each bend and elbow adds resistance for the fan to overcome. Use the shortest, straightest duct routing possible. When turns are required, use large radius elbows to reduce turbulence.

Smooth Interior Surfaces

Spiral seam ducts with smooth interiors prevent friction losses. Avoid flexible ducts with corrugated interiors wherever possible. Seal all connections thoroughly with mastic.

Insulate Ductwork

Insulation prevents condensation buildup and energy loss through duct walls. Use insulation thickness recommended for your climate. Properly seal vapor barrier outside insulation.

Allow Access to Ducts

Include access doors at key points to allow inspection, cleaning, testing and maintenance. This improves air quality and reduces fire hazards from dust buildup.

Proper ductwork design ensures your commercial extractor fan performs as intended. Consult HVAC professionals to match the duct system to your fan’s airflow specs.

Calculate Required Airflow Capacity

Need Better Airflow in Your Commercial Space. Find the Right Extractor Fan Here

To properly size your industrial extractor fan, calculate required airflow in cubic feet per minute (CFM). Factors like room size, usage, occupancy, and desired air changes per hour determine capacity needs. An undersized fan won’t provide sufficient fresh air. Oversizing wastes energy and reduces effectiveness. Consider both summer and winter air densities for year-round ventilation.

Well-designed ductwork allows your commercial extractor fan to deliver optimized airflow.

Calculate Required Airflow Capacity

Maintaining proper airflow is critical in any commercial space, from office buildings to restaurants to warehouses. Without adequate airflow, indoor air quality suffers, creating an uncomfortable or even unhealthy environment for occupants. But how do you determine just how much airflow your space needs? Let’s break it down.

The first step is to calculate the volume of your space in cubic feet. Simply multiply the length x width x height. For example, a room that is 40 ft long by 30 ft wide with a 10 ft high ceiling would be 40 x 30 x 10 = 12,000 cubic feet. If your space has a more complex layout, you may need to break it down into separate areas and calculate each one individually.

Next, you’ll want to account for the number of air changes per hour needed. This varies based on the application – offices and retail spaces typically need 4-8 air changes per hour, while warehouses can be as low as 2-4. Air changes per hour refers to replacing all the air in a space with fresh air that number of times in an hour. More air changes improve indoor air quality but require greater airflow capacity.

To get the required cubic feet per minute (CFM) of airflow, simply multiply the volume of the space by the desired air changes per hour, then divide by 60 minutes. Using our example room size of 12,000 ft3, and assuming 6 air changes per hour, the calculation would be:
12,000 ft3 x 6 air changes/hour / 60 minutes = 1,200 CFM

This means that to maintain 6 air changes per hour in this sample room, an extractor fan system capable of delivering at least 1,200 CFM of airflow would be needed. The required CFM for your specific space can be calculated using this simple formula.

Selecting the Right Extractor Fan

Once you’ve calculated the required airflow for your commercial space, it’s time to select the right extractor fan to deliver it. There are several factors to consider when choosing a commercial fan:

  • CFM rating – Make sure to select a fan with a max CFM rating that meets or exceeds your required airflow.
  • Duct sizing – The fan must be paired with properly sized ductwork to handle the airflow.
  • Motor type – More powerful motors allow the fan to produce higher static pressure for longer duct runs.
  • Single vs. multi-stage – Multi-stage fans can operate at lower speeds to save energy when maximum airflow isn’t needed.
  • Control options – Look for fans with variable speed drives, remote controls, timers, etc.
  • Sound level – Commercial fans can get quite loud, so sound dampening features may be desired.
  • Additional features – Some fans offer handy extras like backdraft dampers, insulated housings, auto-shutters, etc.

Other important considerations for commercial settings include safety certifications like UL-listing, ease of maintenance, warranty coverage, and manufacturer reputation. Be sure to consult with HVAC professionals to size the system appropriately for your exact application and space.

Powerful belt-driven fans paired with sturdy, galvanized steel ductwork often provide the best solution for most commercial spaces. The fan motor type, number of stages, and blade design all impact the airflow capacity and static pressure capabilities. Many commercial extractor fans also offer installation accessories like wall caps, roof jacks, and motor speed controllers.

No matter what fan you choose, proper sizing, installation, and maintenance will be key to ensure it keeps your business space properly ventilated for years to come. A poorly matched or installed fan won’t be able to provide the required airflow. Also be sure the fan location allows the exhaust air to fully evacuate the space. Working with qualified professionals and following all building codes will help the system run optimally.

By first determining the required CFM, then selecting a commercial grade extractor fan system sized to meet that airflow, you can enjoy improved indoor air quality and comfort in your business space. Proper ventilation keeps employees happy, reduces odors, and removes airborne contaminants. Calculating required airflow capacity is an essential first step!

Select Optional Speed Controls for Flexibility

Need Better Airflow in Your Commercial Space. Find the Right Extractor Fan Here

When installing or upgrading the ventilation system in your commercial building, one of the most important decisions is choosing the right extractor fan. Extractor fans, sometimes called exhaust fans, are essential for removing stale, humid air from indoor spaces. With the right extractor fan, you can increase comfort, reduce humidity, and improve indoor air quality.

One key consideration when selecting a commercial extractor fan is whether you need flexibility in fan speeds. Many extractor fans operate at a single, fixed speed. However, you can also choose models with multiple or variable speeds. Opting for an extractor fan with adjustable speed controls provides benefits in many commercial settings.

Match the Fan Speed to Current Conditions

With a single-speed extractor fan, you get only one level of ventilation. The fan runs constantly at maximum speed, regardless of the current conditions in your building. This can result in energy waste, as full speed isn’t always necessary.

By choosing a variable-speed or multi-speed extractor fan, you gain the flexibility to adjust the fan speed up and down as needed. For example, a warehouse may require maximum ventilation when many workers are present and activity is high. However, energy can be saved by turning the fans down during quieter times or in unoccupied areas of the building.

Gradually Ramp Up Fan Speed

Need Better Airflow in Your Commercial Space. Find the Right Extractor Fan Here

Turning a single-speed extractor fan on abruptly can create a sudden blast of air. In commercial kitchens and other spaces, a blast of air movement may be disruptive or redistribute dust and debris. With a variable or multi-speed fan, you can gradually ramp up the fan speed when switching the ventilation system on.

Starting at a low speed and slowly transitioning to full speed results in a more subtle increase in airflow. This prevents drastic blasts of air when the system activates. Gradually ramping up the fan speed can help maintain comfortable conditions in industrial and food service environments.

Save Energy by Adjusting Speed for Demand

Adjusting your extractor fans to match the current ventilation demands in your space is one of the best ways to save energy. Variable and multi-speed fans make this easy to accomplish.

For example, imagine that sensors in a commercial kitchen detect a high concentration of humidity and heat. The ventilation system can automatically bump up the extractor fans to quickly return the kitchen to safe temperature and humidity levels. Once the kitchen air is back in the ideal range, the fans can resume normal speed.

This demand-controlled ventilation reduces energy consumption by avoiding constantly running the fans at maximum speed. The ventilation increases only during peak demand periods.

Reduce Noise Levels When Possible

Extractor fans generate noise from airflow and the motor. This noise increases at higher fan speeds. While the fans must run at high speeds during peak ventilation demands, it’s nice to turn them down during quieter business hours or overnight.

Lowering the extractor fan speed reduces noise, which creates a more comfortable environment for employees and customers. In settings like offices, classrooms and hospitals, minimizing noise can also increase focus and productivity.

Gradually Slow Fans for Controlled Shut Down

Just as a variable-speed extractor fan can gradually ramp up, it can also slowly decrease speed for a more controlled shutdown. Rather than abruptly switching off a loud, single-speed fan, you can incrementally reduce the speed before fully turning off the ventilation system.

Slowing the fans over a period of several minutes allows air movement and noise to dissipate gradually. This prevents an abrupt loss of ventilation that could stir up dust or be disruptive to your commercial environment.

Choosing the Right Speed Options

Need Better Airflow in Your Commercial Space. Find the Right Extractor Fan Here

When installing or replacing extractor fans, look for models that offer:

  • Multiple preset speed settings (low, medium, high)
  • Variable speed via a potentiometer dial or similar control
  • Variable speed via electronic control from an automation system or building management system
  • Automatic speed adjustments via sensors, timers, occupancy etc.

Combining variable fan speed capabilities with programmable logic controllers or building automation systems provides the ultimate in smart ventilation control.

You get all the benefits of demand-controlled ventilation to reduce energy costs. Plus, you can easily adjust conditions room-by-room for optimal occupant comfort and productivity.

Upgrading old, single-speed extractor fans to new variable models can deliver rapid payback through energy savings. And you gain greater control over your indoor air environment.

Just be sure your new extractor fans are sized adequately for peak ventilation needs at maximum speed. A variable-speed fan set on low won’t be beneficial if it’s undersized for the space. Professional sizing guidance can ensure your new fans provide both energy efficiency and sufficient airflow.

By opting for adjustable speed controls when purchasing commercial extractor fans, you gain flexibility to respond to changing ventilation demands throughout your building. Your ventilation system can work smarter, not just harder. Contact a supplier today to explore the many extractor fan speed controls designed for energy savings and custom control.

Key areas covered by electrical codes include proper wire gauge for amperage rating, grounding, junction boxes, conduit type, and more. Cutting corners on codes could invalidate your building’s insurance or result in large fines.

Calculate Required Amperage

The motors that power extractor fans require a certain amperage based on the rated wattage. Smaller, low-speed fans may only draw 1-2 amps. Larger, high-volume fans can draw 10 amps or more, especially on start-up.

Cheap, undersized wiring won’t deliver adequate power. This could cause the fan motors to overheat and malfunction while in use. Have an electrician properly size wiring for the amp load to prevent problems.

Use Dedicated Circuits

Need Better Airflow in Your Commercial Space. Find the Right Extractor Fan Here

Never tap into an existing building circuit to wire up new extractor fans. The fans should have dedicated circuit breakers and wiring. Sharing circuits can overload and trip the breakers, leaving your ventilation offline.

Dedicated circuits also allow you to turn off the fans separately from other equipment for maintenance, repairs or emergencies. It also prevents other appliances on shared circuits from tripping the fans offline.

Include Safety Cut-Off Switches

Electrical safety switches provide an emergency way to cut power to the extractor fan system. Locate cut-off switches near the fans for quick access by staff.

Lock-out mechanisms are also wise to use when performing maintenance on the fans. This prevents someone from accidentally turning the system on while service is in progress.

Ground the System Properly

Always ground your extractor fans as required by code. Proper grounding protects against electric shock by providing a safe path for current in a fault situation.

Use a qualified electrician to install ground wires, rods and connectors. Periodically test ground continuity for ongoing safety.

Weatherproof Components

Need Better Airflow in Your Commercial Space. Find the Right Extractor Fan Here

Seal all roof and wall penetrations properly so moisture cannot leak in. Keep electrical components protected from rain, snow and debris.

Maintain Connections Over Time

Even quality electrical installations require ongoing inspections and maintenance:

  • Check wiring for damage due to wear or rodents
  • Ensure junction boxes and conduit seals remain watertight
  • Test ground continuity annually
  • Inspect breakers for signs of tripping or overheating
  • Check that cut-off switches function properly

Extractor fan motors have a long service life. But eventually motors wear out and must be replaced. When you install new fan motors, upgrade the electrical wiring too. Don’t reuse old wiring beyond its safe usefulness.

As you upgrade your building’s ventilation system, don’t cut corners on the extractor fan electrical connections. Hiring a professional electrician is a wise investment that prevents problems down the road. Adequate power and safe wiring keeps your ventilation system running properly for years.

For help determining your electrical needs, contact a commercial ventilation supplier. Look for extractor fans that include voltage, amperage, and circuit breaker requirements in the product specifications. With the right electrical setup, your fans will provide energy-efficient airflow for superior indoor air quality.

Find Models for Washdown or Dusty Areas If Needed

Industrial sites often contain areas that are washed down frequently for cleaning and sanitation. Other spaces may simply be extremely dusty due to manufacturing processes or stored materials. Standard extractor fans are not designed for these demanding environments. Choosing washdown or dust-resistant models ensures reliable operation.

Specialized extractor fans prevent moisture and debris from damaging important internal components. While more expensive than standard fans, they are a wise investment for food processing, metalworking, textiles, and other washdown or dusty commercial settings.

Frequent Washdowns Require Waterproofing

In food prep areas, hygiene is essential. Walls, floors and equipment get sprayed down and scrubbed multiple times per day. Even extractor fans mounted high up eventually get hit by cleaning sprays.

Moisture seeping into standard fan motors and wiring leads to corrosion, shorts, and eventual failure. Choose extractor fans specially designed to resist high-pressure washdowns. Check specs to confirm the washdown rating matches your cleaning needs.

Utilize Protective Shrouds

Need Better Airflow in Your Commercial Space. Find the Right Extractor Fan Here

Some heavy-duty extractor fans feature a plastic shroud or cover surrounding the motor and other internal parts. The shroud acts as a protective barrier, keeping water out.

Make sure shrouds provide complete coverage. Look for designs with overlapping seams and water-tight sealing gaskets. The shroud should have a drain hole to let water escape rather than pool up inside.

Go for Stainless Steel Housing

Another option for wet environments is an extractor fan enclosed in stainless steel housing. Stainless steel resists corrosion from repeated washdowns far better than standard steel.

However, stainless steel can eventually succumb to moisture damage. Make sure any unprotected motor and wiring remain sealed off. Dip these components in epoxy for extra waterproofing.

Get Washdown-Rated Motors and Bearings

The fan motor and bearings are especially vulnerable components. Look for extractor fans with motor and bearings rated for washdown duty.

Sealed bearings prevent moisture intrusion under pressure. Special motor windings and contacts resist corrosion better for longer service life.

Use Spark Resistant Components in Combustible Areas

Need Better Airflow in Your Commercial Space. Find the Right Extractor Fan Here

If extractor fans will be located where flammable vapors or dust may occur, choose spark resistant models. These fans use special motors, blades and housings that won’t create static sparks.

Avoid open contact switches that can arc. In high risk areas, explosion-proof extractor fans are required. They contain any internal sparks and prevent ignition of the outside atmosphere.

Dust Resistance Prevents Wear and Clogs

Just as moisture can damage fans, so can excessive dust and particulates. Industrial finishing processes often generate heavy airborne dust. The tiniest particles can work their way into any unsealed component.

Excess dust buildup on fan blades also throws off balance, causing vibration issues. Blades can erode over time from abrasive particles hitting at high speeds.

Seeking out dust-resistant commercial extractor fans is wise for reliability in very dusty spaces:

  • Sealed bearings prevent dust intrusion
  • Smooth housing surfaces discourage dust adhesion
  • Epoxy or gel coatings create a barrier
  • Filtered fresh air intake prevents particle ingestion

Washdown-rated fans are inherently dust-resistant as well. Just take care to match the fan’s protection level to the degree of moisture, corrosives, and particle debris present in your unique environment.

Ensure Support and Maintenance Accessibility

While rugged extractor fans are built to withstand challenging conditions, they still require periodic maintenance and eventual motor replacement.

Make sure fans in difficult locations can be accessed safely by technicians. Install catwalks and ladders as needed. Leave room for tools and parts to be brought in during service work.

Discuss maintenance contracts up front. Specialized fans often require manufacturer authorized service due to their unique construction. Factor in any premium ongoing maintenance costs.

In the right commercial settings, heavy-duty washdown and dust-resistant extractor fans provide critical ventilation. Their robust design keeps the fans running reliably despite frequent cleanings or contamination. Contact an industrial ventilation company to determine if specialized models are right for your facility.

Compare Brands Based on Quality and Reliability
