Are your fans VFD compatible?
Don’t assume that all motors are VFD compatible. The majority of our fans are mounted with “inverter ready” motors with the exception of single phase motors. If you are interested in controlling air flow and boosting energy efficiency, contact us and we’ll help you select the best fan, motor and VFD to meet your needs. Click here to read more about it.
Can you make an explosion proof fan?
Yes, the majority of our explosion proof fans are at least rated for Class I group D and Class II groups F & G, which covers certain flammable gases, combustible vapors, and combustible dusts. Specifically-rated motors are available on request. We also use a cast aluminum propeller on fans located in hazardous locations. Click here to read more about it.

How do I size a shutter for a wall fan?
A WS-30 shutter has an inside frame dimension of 30” x 30”, but the overall frame dimension is 33” x 33”, which includes a 1 ½” flange on all sides. All of our wall exhaust fans measure 6” more than the diameter of the fan. Therefore, our 30” wall exhaust fans have an overall panel size of 36” x 36”. A WS-30 or WS-36 shutter would work depending on how you mount the fan. Click here to read more about it. There are multiple ways to mount a fan, and we have accessories to assist in the process.
How long will the fan last?
Our fans should last a minimum of 20 years, although we’ve had past customers requesting replacement parts after longer spans of time. To ensure trouble free operation and long life for a fan assembly, a preventative maintenance program that includes regularly scheduled inspections and lubrication is recommended. The frequency of inspection and lubrication depends upon the fan, its components and operating conditions. Click here to read more about it.
