Sizes available are: R100, R125, R150, R160, R200, R250, R315.
Cased Axial Fans
)
The cased axial fans are made from galvanised and powder coated steel complete with two flanges. The impellor is mounted on a speed controlled external rotor motor. The motor is protected against humidity and thermal contacts and embedded in the windings.
Plate Axial Fans
)
The plate axial fans are made from galvanised and powder coated steel and are fitted to retangular plates ready for wall mounting. A cable termination box is supplied lose.
Ultra-Flat Centrifugal Fans
)
The ultra flat series fans have been designed to provide low noise ventilation especially in ceiling or floor voids. The 0-100% speed control through a variable transformer provides a hum free environment and hence a low noise ventilation is achieved. The ultra flat fan is used in the CMR Ultra flat airhandling unit.
