Frequently Asked Questions

How do I choose the correct fan size?

Select the fan based on the required airflow (CFM) for your space. Larger blade sizes produce higher CFM ratings and are suited for larger buildings or applications requiring rapid air exchange.

Consider:

  • Total cubic footage of the space
  • Desired air changes per hour
  • Heat load or equipment output
  • Ventilation purpose (general exhaust vs heat removal)

Are these fans belt-driven or direct-drive?

All wall mount panel exhaust fans are belt-driven.

Benefits of belt drive include:

  • Smoother operation
  • Reduced vibration
  • Longer motor life
  • Easier servicing

What voltage do these fans require?

All units ship pre-wired for 115V and can be converted to 230V.

Always verify your electrical supply before installation and ensure compliance with local electrical codes.

What materials are these fans made from?

  • Aluminum blade
  • Aluminum shutter
  • Permanently lubricated bearings
  • UL-listed motor

These materials are selected for durability and reliable performance in general ventilation environments.

What type of air are these fans designed to move?

These fans are intended for general-purpose exhaust of relatively clean air, including:

  • Heat removal
  • Air circulation
  • General building ventilation

They are not designed for explosive, corrosive, or grease-laden environments unless specifically rated for those applications.

Are mounting hardware and electrical components included?

These products include the fan unit only. Structural framing, mounting hardware, wiring, and electrical disconnects must be supplied separately according to your installation requirements.
