AMCA Certified Ratings

Central Blower Co. certified that the Backward Inclined Blowers shown here-in are licensed to bear the AMCA Seal. The ratings shown are based on tests and procedures performed in accordance with AMCA Publication 211 and comply with the requirements of the AMCA Certified Ratings Program.
Wheel Accurately machined from turned, ground and polished steel shafting.
Closely checked for diameter and straightness.
Housing Heavy gauge, galvanized steel, all welded construction provides rigid support for housing, motor, shaft and bearings.
Inlet Cone Designed to efficiently force air through the blower housing with backward inclined blades set at the proper angle to prevent overloading of the motor. All sizes 12-BI through 36-BI are equipped with steel wheels as standard equipment and with aluminum wheels as optional equipment when AMCA type B spark resistant construction is specified. Sizes 9-BI and 10-BI are equipped with aluminum wheels as standard equipment. Wheels are dynamically balanced and are available in CW and CCW rotation.
Weather Cover Constructed of heavy gauge steel. Available in eight discharge positions. When ordered from factory, blower will be assembled in discharge position specified.
Bearings Spun steel construction, smoothly contoured to guide air into wheel with minimum turbulence. Unobstructed inlet to provide quiet operation.
Motor Base Rust resistant galvanized steel construction protects the shaft, bearings, motor and drives from the weather. Also serves as a OSHA approved belt guard.
Motors & Drives Self-aligning ball bearing pillow blocks are provided on all models.
Eccentric collars securely lock the inner race to the shaft. Pre-lubricated and sealed to retain lubricant and exclude dust and moisture, provide extended long life.
Heat Slinger Heavy gauge galvanized steel base, pivoted at one end and supported at the other by threaded rod for easy belt adjustment. Hinge type construction insures that the motor shaft will remain parallel with the blower shaft when adjusting belt tension.
Drain Fitting Standard motors are NEMA open-drip proof, available to match all requirements for H.P., RPM and electrical power. TEFC, 2-speed and explosion proof motors also available.

All Central BI blowers with motors up through 10 H.P. are equipped with adjustable pitch motor pulleys. 15 H.P. and larger are normally equipped with constant speed drives. V-Belts supplied are rated to transmit 150% of motor horsepower and are oil resistant and static dissipating. Factory installed motors and drives are carefully checked for smooth operation, and compliance with specifications for RPM and amperage.
Disconnect Switch
Designed to prevent over-heating of bearing for blowers handling air at temperatures over 250°F. Consists of an aluminum disk mounted on the blower shaft between the blower housing and bearing to dissipate the heat from the shaft.
Vibration Isolators 3/4” NPT coupling welded to low point of housing. Recommended where condensation or rain water might accumulate inside the housing. Plastic pipe plug supplied.
Spark Resistant Construction Available to match HP and power characteristics of the motor supplied
Inlet & Outlet Flanges
Rubber In-Shear Pads: Available for units up to 18-BI size. Suitable only for non-critical applications.

Individual Spring Mounts: Provide approximately 1" vertical deflection. Designed for critical applications.

Spring Rails: Consists of spring isolators attached to rails to provide more even distribution of weight. Both individual or rail type provide seismic restraint.
Acid Resistant Coatings Conforms to AMCA Type “B”. Requires non-ferrous wheel. AMCA Type “A” available. Consult factory.
Automatic Backdraft Dampers Available on special orders. Allow extra delivery time.
Cleanout Door Electrostatically applied epoxy recommended for most fume hood or similar applications. Other coatings are available for more extreme conditions.
Inlet & Outlet Screens
Designed to prevent reverse flow of air when blower is not operating. Made to fit blower discharge. Also available with built-in bird screen.
Warranty Provides access for cleaning or inspection of the interiors of the housing. Cover plate bolted with steel fasteners and fully gasketed.
