1． Enable the selection of different power levels thus to get the
best match of price and performance according to customers’load
requirements
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

Construction
Cowls are of galvanised steel construction.
Impellers are backward-curved centrifugal design and are of high
performance composite material.
Bird-mesh guards are an optional extra.
Powder-coating is an optional extra.
Special Note
Backdraft shutters are an optional extra. The pressure loss across
the shutter has to be added to the system pressure before making
selections.
All GL Gamma EC models can be pre-configured to suit specific
sensors and specific applications. Please advise Fantech of these
