FAQ Sumarry from Engineer and Customer

How to choose a suitable fan or blower for AHU,FFU or other ventilation equipments ?

When selecting a fan for a specific application, these parameters play an important role:

– Air flow with given back pressure
– Voltage supply, divided into DC and AC voltage (1~, 3~)
– Noise generation
– Efficiency
– Available mounting space

What is the operating conditioning requirements for the EC backward centrifugal fan ?

Operating temperature:-25~60℃,Operaing humidity : 0 – 85% RH;
Storing temperature:-25~70℃,Storing humidity: 0~ 95%RH
Applicable altitude range: <1000m
or Customized ,contact our engineer team 

What is the electronic protection function included in this backward centrifugal fan ?

Electronic / Thermal protection for this product
EC motor : Control input 0-10VDC/PWM, Tech output, Locked-Rotor protection, Reverse Polarity,
Over-voltage protection, Soft Start Protection(Delay time <35 seconds to full speed)
Information on motor protection and thermal protection is provided in product-specific data sheets.
The following protection methods are provided depending on the type of motor and area of application:
– Thermal overload protector, in-circuit or external ;
– PTC with electronic diagnostics;
– Impedance protection ;
– Thermal overload protector with electronic diagnostics ;
– Current limitation via electronics ;
If use is made of an external thermal overload protector, a commercially available tripping unit must be connected by the customer for shut-off. Motor protection conforming to the applicable standard must be fitted for products not provided with a built-in thermal overload protector and not protected against improper use.
