round silent axial flow blower fan 220V, window mounted exhaust fan
Product Advantage
1. compact structure and small size
Integral design of motor makes the whole structure more compact and
the axial dimension reduced.
2. wide speed regulation range, smooth start-up and low start-up
current
Special squirrel cage rotor structure and one-time die casting
process ensure smooth start of motor, low start-up current, wide
speed range and smooth speed regulation.
3. low noise, small vibration, energy saving and high efficiency
With advanced specification and manufacturing technology, the main
parts have high processing accuracy, smooth operation, low noise
and small vibration; high quality electromagnetic material and
special electromagnetic structure design to ensure high efficiency
of motor.
4. strong adapt ability
It can be widely used in cold ventilation industry such as duct
fan, roof fan, environmental air conditioning, condenser,
evaporator etc.
