Ehigh Volume Fans Blowers 1900m3/H EC 355mm Air Central Ventilation
1． Enable the selection of different power levels thus to get the
best match of price and performance according to customers’load
2． As the rotor is mounted to interior, the external rotor fan is
more compact constructed, smaller and easy to abstract heat., thus
ensure to maximum the reliability of fan operation,
Sustainable speed control benefits to achieve low operating costs,
reduce CO2 emissions protect the environment, enable the direct,
simple communication between the host controller and the system

The GL Gamma EC Series of centrifugal roof mounted exhaust fans
incorporate the latest state of the art, energy saving EC motor
They feature integrated infinitely variable speed control and
eliminate the need for external VSDs, current overloads and motor
The compact and low profile GL Gamma EC Series is a simple "plug
and play" system which means installers do not need to have
specialised control programing knowledge.
Matching sensors can easily be connected to monitor the ambient
conditions in a space and provide real time feedback to the fan.
The fan's on-board microprocessor can adjust the speed and
therefore modulate the ventilation rate to match the specific
requirements of the area.
They are suited to ducted vertical exhaust applications, include a
removable windband that provides easy access for cleaning and
maintenance, and are available in 315, 355, 450, 560 and 630mm fan
