INDUSTRIES AMERICAN COOLAIR CORPORATION Centrifugal Filtered Supply Roof Ventilators TYPE CFS - TYPE SIS
CFS Centrifugal Filtered Supply Fans Applications The CFS Centrifugal Filtered supply fans with four (4) side inlets are designed for roof mounting on curbs to provide make-up filtered air to general ventilation systems. Applications include a variety of commercial and industrial facilities as well as commercial and industrial kitchens. Construction Construction of the CFS power roof ventilators is mill galvanized steel throughout the unit. The blower has a DIDW centrifugal wheel with forward curved blades finished in a matte zinc coating. The blower housing is constructed of galvanized steel. The blower features sealed and permanently lubricated ball bearings suitable for operation from -65 degrees to +50 degrees F (check motor capability). The blower is mounted to the fan housing using rubber isolation grommets. Filters are aluminum mesh, cleanable and held in place by a u-channel frame. UL705 E39944 Guide Specifications Type CFS ventilators are Listed by Underwriters Laboratory Inc. to US and Canadian safety standards. American Coolair Corporation, ILG Industries Division certifies that the Type CFS units shown herein are licensed to bear the AMCA Seal. The ratings shown are based on tests and procedures performed in accordance with AMCA Publication and comply with the requirements of the AMCA Certified Ratings Program. Access to the fan, motor, drive and filters is accomplished by removal of the top utilizing four (4) thumb screws. A factory wired disconnect switch is an available option. Drive Mechanism CFS models have a V-belt drive with adjustable cast iron motor pulley for adjusting fan operating speed. Drive shaft is turned, ground and polished. Motor support is adjustable for proper belt tensioning. Motors NEMA standard open drip proof motors are prelubricated and located in the air stream. Other motors may be available. All motor brands are recognized and serviced nationwide. Motor enclosure required may affect UL Listing. Filtered supply fans shall be of the CFS centrifugal type as manufactured by ILG Industries of American Coolair Corporation (individual models to be listed in fan schedule). Units shall bear the AMCA Certified Ratings Seal for air performance. Housing and frame of the fan are to be galvanized steel. The top of the unit is to be removable for access to the inside fan components, filters and drive. The blower is to be mounted to the fan housing using rubber isolation grommets. Drive mechanism shall incorporate a V-belt drive with cast iron motor pulley. The centrifugal wheel shall be heavy gauge zinc-coated steel with forward-curved blades. Motor shall be open drip-proof construction, NEMA design B with minimum service factor of.5. Adjustable motor pulley shall be provided to allow for field adjustment and system balance. Motor shall be mounted on an adjustable steel mounting bracket. (Mounted and wired disconnect switch, backdraft damper, epoxy coating and other accessories shall be listed in the fan schedule.)

Installation Most models are shipped fully assembled and ready for installation. Always inspect equipment for transit damage before accepting delivery to assure valid claim. Special handling and storing procedures are required if unit is to remain idle for an extended period of time before installation. Placement: All units must be accessibly installed for maintenance and servicing of belts and bearings, and for routine cleaning. Mounting: Satisfactory operation of ventilators requires mounting on adequately designed and constructed roof curbs. Pre-fabricated curbs for convenience in installation are available from ILG. Install with base of unit horizontal. Provide adequate caulking, flashing or other weatherproofing means. Duct connections are made below unit. Inspection: Check centrifugal wheel for free rotation. Check belt for proper tension. Check motor and fan sheave faces for proper alignment. Check circuit phase, voltage and wiring connection against that shown on motor nameplate. Check direction of fan rotation for proper air flow. After one week of operation, check belt for proper tension. Maintenance Units should be checked and cleaned monthly for the first two or three months, and periodically thereafter. Regular Inspection: Units should be cleaned of material build-up every three months or when necessary, depending on condition of air and frequency of use. Any eroded parts should be replaced to avoid structural damage and possible failure. Belt Adjustment: Belt alignment and tension should be adjusted if necessary. Inspection every 6 to months is recommended. WARNING CAUTION DO NOT INSTALL FAN WITH MOVING PARTS WITHIN 8 FEET OF FLOOR OR GRADE LEVEL WITHOUT A GUARD THAT COMPLIES WITH OSHA REGULATIONS. DO NOT USE UNLESS ELECTRICAL WIRING COMPLIES WITH ALL APPLICABLE CODES. DO NOT WIRE WITHOUT PROVIDING FOR A POWER SOURCE DISCONNECT AT THE FAN ITSELF. DO NOT SERVICE EXCEPT BY A QUALIFIED MAINTENANCE TECHNICIAN AND ONLY AFTER DISCONNECTING THE POWER SOURCE. FAILURE TO OBSERVE THESE PRECAUTIONS CAN RESULT IN SERIOUS INJURY OR DEATH. Options and Accessories Pre-fabricated Roof Curbs Insulated roof curbs with weather-proof continuous welded construction are available for both insulated and non-insulated roof decks. Special Motors Two-speed, totally enclosed, energy efficient and explosion-proof motors for hazardous locations may be available for many models. Motor requirements may affect UL Listing. Backdraft Dampers Gravity or motor operated backdraft dampers are available. They are aluminum construction and designed for installation in prefabricated roof curbs. Safety Disconnects Safety disconnects cut power to motor for servicing of unit. A disconnect switch is an option for CFS and SIS units and may be shipped loose for field installation or factory mounted and wired. Protective Coatings Fan units are not recommended for ventilating air of a corrosive nature. However, special protective coatings are available where units may be exposed to corrosive exterior conditions. Parts requiring painting are processed through the American Coolair fivestage pretreatment system prior to the application of any coatings to insure maximum finish adhesion. These parts use a thermosetting epoxy powder paint with an average thickness of 3 mils and baked at 400 F to a smooth, hard continuous finish. Consult your ILG Industries representative for available coatings.
