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 triping unit must be connected by the customer for shut-off Motor protection conforming to the aplicable standard must be fitted for products not provided with a buit-in thermal overload protector and not protected against improper use.
