CF Master
is available in four sizes: 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 10,680 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 54 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.
The modular design propellers
we use 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 avialable 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.
California Turbo, Inc. reserves the right to make product changes
