Catalog FC-04 OCTOBER 2004

STANDARD FEATURES WHEELS Multivane forward curved wheel. They are designed to move the maximum volume of air with a minimum wheel speed, which results in quiet operation. All Central wheels are dynamically and statically balanced.

HOUSINGS

Made of heavy - gauge, zinc coated steel with electric welded construction. The discharge can easily be changed in the field to any one of eight different positions. The inlet connections are sized to fit standard sheet metal conductor pipe.

FRAMES

Ruggedly constructed of heavy galvanized angles. The open construction provides easy access for mounting of and wiring to motor. On models FC-109 and FC-111 the motor is mounted above the blower shaft to provide easy access for wiring and belt adjustment.

BEARINGS Self-Aligning ball bearing pillow blocks are supplied on all models. Bearings are pre-lubricated and equipped with labyrinth seals to retain the lubricant and to exclude dust and moisture. Both bearings are mounted out of the air stream for long life. SHAFTS

Ground and polished C1045 steel, protected by a rust preventive coating.

DISCHARGE POSITIONS

MOTOR BASES Heavy gauge galvanized steel base, pivoted at one end and supported at the other by two threaded rods for easy belt ajustment. Hinge type construction insures that the motor shaft will remain parallel with the motor shaft when adjusting belt tension

DRIVES

V - Belt drives are available to cover the air volume and pressure range of each model. V - belt drives provide for adjusting the blower speed to the exact RPM needed to supply the desired air volume and static pressure. The variable pitch motor pully is easily adjustable to provide approximately ten percent ( 10% ) variation in blower speeds.

MOTORS Fan duty - type motor of nationally

recognized manufacturers are available. NEMA standard, single speed, 1725 RPM, open drip proof motors are normally furnished when units are ordered with motor and drives. See next page regarding special motors that are available.

DRIVE COVER

Weather - proof enclosures of galvanized steel are standard equipment on all model. Cover provides guarding for the belt drives and rotating shaft to meet safety codes and protects the motor and drives from the weather. Housings are made of special zinc coated steel and then finished in weather resistant baked enamel. The wheels and drives covers are made of rust resisting galvanized steel. See the next page for information on special finishes.

FINISHES

ROTATION IS DETERMINED BY LOOKING AT CLOSE END ( MOTOR END ) CW SHOWN ABOVE Central Blower Catalog - 1

OPTIONAL FEATURES VIBRATION Available in a varierty of types: ISOLATORS Rubber - in shear isolator pads,

Individual spring-type mounts or spring-rail type mounts are stock items. Earthquake restraint mounts are available.

AUTOMATIC DISCHARGE SHUTTER

For prevention of backdraft or for weather protection.

DRAIN CONNECTION

3/4-inch pipe coupling welded to the low point of the housing for draining of water or grease that might accumulate in the housing. Weep hole also available without pipe connection.

SPARK RESISTANT CONSTRUCTION

AMCA Type “B” spark resistant construction is available on all sizes of Central FC Blowers. AMCA standard #401-82 requires that the fan shall have a non-ferrous rubbing ring about the opening through which the shaft passes. AMCA Type “A” contruction is available for most models at extra cost and additional lead time. For Type “A” construction, in addition to the requirement for Type “B”, all parts in contact with the air stream shall be of non-ferrous material.

RECOMMENDED SPECIFICATIONS FOR ORDERING Furnish and install where shown on plans, a Central Blower Co. Forward Curve belt-driven blower. Blower shall have ball bearing pillow-block which shall be mounted out of the airstream and shall be driven by a V-Belt drive having a variable pitch cast iron motor pulley. The electric motor, drives and shaft shall be protected by a weatherproof drive cover. Blower wheel shall be multivane type with forward curved blades and be dynamically balanced. Housing shall be convertable to any of eight discharge positions Additional specifications are as follows: CFM________S.P.________O.V.________H.P_________

SPECIAL Totally - Enclosed, Explosion Proof, MOTORS High Efficient, two-speed and other

special motor can be furnished. 208 volt either single or three phase are available. Automatic Thermal Overload Protection is standard in single phase motors through 2 HP. Three phase motors are available with built-in overload protection on some models through 5 HP at nominal added cost. Corrosive fumes may require special SPECIAL COATINGS coating. Epoxies, and Halar are

available to resist the effects of acids, alkalies, solvents etc. For more information on special coatings, contact Central Blower Company.

PROTECTIVE Inlet screens protect unit from debris when used on supply application. Outlet SCREENS screens prevent entrance of birds and serve as a safety guard for rotating blower wheel.

APPLICATIONS These forward curves blowers, because of their quiet operation are ideally suited for supply or exhaust applications in a wide variety of buildings. Typical uses are for ventilation or exhaust in restaurants, schools, office buildings, theaters, industrial plants and laboratories. The Spark Resistant models are ideal for exhaust applications where explosive vapors, gases or dust might be present in the exhausted air.

Central Blower Co. certifies that the Foward Curve Blowers shown herein 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 AMCA Certified Rating Program.
