CANARM AX & P Series Exhaust Fans

Product Information

  • The AX & P Series Exhaust Fans are sturdy and reliable models designed for ventilation purposes in hazardous areas. The AX Series features a rugged, sturdily constructed housing made from all aluminum extrusions. The louvers open automatically when the fan starts up and close when the fan stops. On the other hand, the P Series is a sturdily constructed panel-mounted exhaust fan made with a durable powder-coated finish. Both models come equipped with single-speed explosion-proof motors and aluminum blades that prevent sparks from occurring if a metal object obstructs the blade path.
  • Canarm explosion-proof fans are designed to meet hazardous classifications such as:
    • Class 1, Division 1 (Gases, Vapors)
    • Class 2, Division 1 (Combustible Dusts)
  • However, the fans do not meet Class 1, Division 1 (Gases, Vapors) for Group C and Group D hazardous areas.

Product Usage Instructions

INSTRUCTION MANUAL FOR AX & P SERIES EXHAUST FANS

READ INSTRUCTIONS COMPLETELY BEFORE INSTALLATION & SAVE FOR REFERENCE
Congratulations on the purchase of your quality built direct drive, wall exhaust ventilation fan. All of these models use totally enclosed motors with thermal overload protection. Variable speed motors are high efficiency motors which save on electrical costs and can be run as a single speed motor. The motors are mounted on heavy gauge welded steel rod motor mounts that have a Bright Zinc finish. 30” fans and larger have powder coated guards. Fans come fully assembled and 100% of fans are tested for proper operation before shipping.
THESE ARE GENERAL INSTRUCTIONS WHICH COVER OUR SINGLE, VARIABLE AND TWO SPEED AX & P FANS, AS WELL AS OUR SINGLE SPEED EXPLOSION PROOF MODELS.

AX & P SERIES EXHAUST FANS

Explosion proof fans are equipped with single speed explosion proof motors and aluminum blades so sparks cannot occur if a metal object obstructs the blade path. Explosion proof fans have the same quality housing panel and heavy gauge welded guard as the AX & P Fans. These fans should be used to ventilate hazardous areas. Locations are considered hazardous if the atmosphere contains or may contain gas, vapor, or dust in explosive quantities.

THE MOTOR AMBIENT TEMPERATURE IS NOT TO EXCEED +40˚C OR -25˚C UNLESS THE MOTOR NAMEPLATE SPECIFICALLY PERMITS ANOTHER VALUE. THE FOLLOWING TABLE INDICATES WHICH HAZARDOUS CLASSIFICATIONS CANARM EXPLOSION PROOF FANS DO AND DO NOT MEET.

Canarm explosion proof fans DO meet the following hazardous classifications.

CLASS 1, DIVISION 1 (GASES, VAPORS)

GROUP C Acetaldehyde, cyclopropane, diethlether, Ethylene, isoprene

GROUP D Acetone, acrylonitrile, ammonia, benzene, butane, ethylene dichloride, gasoline, hexane, methane, methanol, naphtha, propane, propylene styrene, toluene, vinyl, acetate, vinyl chloride, xylene

CLASS 2, DIVISION 1 (COMBUSTIBLE DUSTS)

GROUP F Carbon black, coke or coal dust

GROUP G Flour, starch or graindust

| Canarm explosion proof fans DO NOT meet the following hazardous classifications.

CLASS 1, DIVISION 1 (GASES, VAPORS)

GROUP A Acetylene

GROUP B Butadiene, ethylene oxide, hydrogen, propylene oxide

CLASS 2, DIVISION 1 (COMBUSTIBLE DUSTS)

GROUP E Aluminum, magnesium and other metal dusts with similar characteristics

INSTALLATION

Installation is fast and simple. A sturdy framed wall opening should be prepared in advance to the size indicated for your fan in the charts above. With lag bolts for wooden frames or nut, bolt and lock washers for steel frames, secure the fan using the four mounting holes provided, one in each corner of the fan.

ELECTRICAL CONNECTIONS

WARNING: BE SURE POWER IS OFF AT THE ELECTRICAL PANEL BEFORE WIRING.
WARNING: ALL ELECTRICAL WORK SHOULD BE PERFORMED BY A QUALIFIED ELECTRICIAN.
These fans are supplied with single, two or variable speed motors. Single and two speed motors are 120V only. Variable speed motors are dual voltage. All dual voltage motors are pre-wired at 240V in our factory. Rewire motor as per motor nameplate if running fan at 120V. Please see the motor nameplate for wiring diagram. Make electrical connections in motor connection box as per the motor nameplate. Follow Chart #1 for wire sizes. Two speed fans require a two speed control or 3 position toggle switch to change from high/low/off. See wiring diagram with control for 2 speed wiring instructions.

OPERATION

  • WARNING: VARIABLE SPEED FANS SHOULD HAVE THE MINIMUM SPEED SET TO OPEN LOUVERS AT LEAST ONE INCH FOR PROPER MOTOR COOLING AND TO PREVENT MOTOR FAILURE.
    All fans are direct drive. Fans with variable speed motors can be operated as an energy efficient single speed fan or in variable operation with the proper controller. As mentioned above two speed fans require a two speed control or 3 position toggle switch to change from high speed to low and off.

  • WARNING: GUARDING SHOULD BE USED IF FANS ARE MOUNTED LOWER THAN SEVEN FEET (2 METRES) OFF FLOOR OR GROUND LEVEL.

ACCESSORIES

Canarm provides a complete line of manual and thermostatic controls. Canarm also offers wall mount exhaust shutter kits, replacement shutter sets, and weather protection hoods.

MAINTENANCE

MOTORS ARE EQUIPPED WITH AUTOMATIC OVERLOAD PROTECTION AND MAY RESTART WITHOUT WARNING. ALWAYS DISCONNECT FROM POWER BEFORE ATTEMPTING SERVICE. Motor, blade and louvers should be kept clean of any buildup to prevent premature motor failure and to achieve proper performance. Automatic louvers should be kept operating freely. As with all mechanical equipment scheduled inspections should include checking that all hardware is secure and blade set screws are tight.
