CF Master Features

TRANSFORMER COOLING FANThe CF Master transformer cooling fan is available in five sizes: 12", 16", 18", 24" and 27" cast aluminum propellers.

All of or fans have OSHA-compliant guards (all openings are less than 1/2"). Guards are heavy duty, hot dip galvanized for durability. Standard airflow up to 8,880 CFM. Motors are securely connected to the guard by 3/8" stainless steel bolts.

All of our motors are custom manufactured in the U.S.A. by well known companies. Our standard motor has a 400 series stainless steel shaft. They are totally enclosed, C-face with removable drain plugs (IP 55 with the plugs installed). They feature class F Insulation, 5/8" shafts with permanently lubricated shielded ball bearings. Motors are rated for 55° C ambient temperature, continuous operation.

Our modular design propellers offer you a wide spectrum of airflow vs. noise. We can readily change the diameter or pitch of our propellers to offer custom configured fans for lower noise or higher airflow.

We can even optimize fans for 50 Hertz operation. Many manufacturers are limited to one sand-cast propeller for each fan that they offer. Our modular propeller offers an unlimited combination of diameters and blade angle to get the most out of the motor you have paid for. Our 50 Hz optimized fans deliver the maximum airflow available from the motor's horsepower. Some additional manufacturing time is required, please contact our Sales Department for more information.

The 24 inch and 27 inch fans below have been optimized for 50 Hz operation. They feature propellers specifically designed for the lower RPMs delivered by a motor operating on 50 Hz current.

These fans must only be operated at 50 Hz. 60 Hz operation will overload the motors causing premature failure.

* Test Method: AMCA 210-99, fig. 12/ ISO 5801, fig. 71b, fan installation type A, free inlet and free outlet. Other impeller arrangements will affect the performance.
** Sound levels listed here were determined under laboratory conditions. Many factors can influence fan sound levels that are beyond the control of the propeller manufacturer or California Turbo, Inc; including inlet geometry and obstructions in the airflow. Please use this information for comparison purposes only.
NOTE: Electrical and noise data are supplied by the motor and propeller manufacturers, respectively. These values have not been independently verified by California Turbo, Inc.
