Solar ventilation system Brushless DC Roof Fan with Backward Centrifugal from GP Motor with High Efficiency ,impeller diameter from 133 to 500.

0-10V and PWM Speed regulation,Integrated protection,application with simple controllability and lower running cost makes EC technology very attractive such as solar ventilation system of DC Roof Fan,DC duct Fan.

All DC roof fan of Backward Centrifugal Fan can be ventilated to reduce the temperature of the blanket of hot air within the roof space.The efficiency of air conditioners is improved by removing heat from around the ducting and thus running costs are decreased.

DC/EC Roof Fan with Backward curved Centrifugal Fan feature:
Low noise

Cyclone tested

No maintenance

No daytime running costs

Environmentally friendly

Only operates when it is hot

Reduces running cost of air conditioning.

Automatically stops when temperature drops
