Our model CAF is a filtered exhaust fan, excellent for use where intake or exhaust air is required. Built on our direct drive wall fan model 900, it supplies clean, filtered air for OEM machinery and equipment markets such as pressurizing electrical cabinets. It is also an economical choice for small unducted paint spray booths.
The CAF is constructed to fit standard filter sizes, and for easy access for filter replacement, this fan comes standard with 2″ MERV 8 filters that can be switched out depending on your needs. Custom builds are also available if you have certain filter or CFM requirements. All fans also include our aluminum gravity shutter to prevent air movement when the fan is off.
