Canarm / LFI's Explosion Proof Fans follow a tradition of quality in design, materials, and construction. Using our quality "Standard Fan" housing and motor mount as the basis for design, we have developed an efficient, economically priced Explosion Proof Fan. All Explosion Proof Fans have a single speed, dual voltage explosion proof motor that meets and conforms to the following standards:
CLASS I, GROUP C - Atmospheres containing ethyl ether, ethylene, gases or vapors of equivalent hazard.
CLASS I, GROUP D - Atmospheres such as acetone, ammonia, benzene, butane, cyclopropane, ethanol, gasoline, hexane, methane, natural gas, naphtha, propane, or gasses or vapors of equivalent hazard.
CLASS II GROUP F - Atmospheres containing carbonaceous dust, including carbon black, charcoal, coal, or coke dusts that have more than 8% total entrapped volatiles, or dusts that have been sensitized by other materials so that they present an explosion hazard.
CLASS II GROUP G - Atmospheres containing combustible dusts not included in group E or F, including flour, grain, wood, plastic and chemicals.
All fans use a totally enclosed, ball bearing motor with thermal overload protection.
The motor mount is manufactured with heavy welded rods and has a powder coated finish.
The fan blades are well-balanced, heavy gauge aluminum.
The rugged steel welded box housing has a durable powder coated finish.
Aluminum shutters are supported by long life nylon bushings.
All fans are shipped completely assembled.

QUESTIONS & ANSWERSAsk a Question
Hi- Do the shutters open and close automatically as the fan is turned on and off? Thank you
Yes, these are what they call gravity dampers or shutters.
What's the difference between SD and ax series?
The SD series exhaust fans are housed in powder coated steel, whereas the AX series fans are housed in extruded aluminum.
Can you build this with a 3 phase explosion proof motor? That would allow vfd drive to control speed.
These fans are not able to be fitted with a 3 phase explosion proof motor. Also, explosion proof motors are not designed to be variable speed, or to run with a VFD. They are single speed only: On or Off
Can I use one of your speed controls on this fan?
No. Explosion proof motors are designed for single speed or On / Off use only.
How well do shutters seal up?
These are gravity dampers and not motorized, so when the fan is off the louvers drop to closed position. They will chatter if there are high winds. It is suggested to purchase the optional Weather Hood as a preventative measure for high winds and driving rains.
what is the rough opening for the wall?27inch by 27inch?
Yes. A 27” x 27” rough-in opening will give a 1/4” gap to work with.
