Replace Ebm-past Ec Centrifugal Fans With Air Purification Pa66 133mm

Although OFAN, the market leader in EC technology, is a China company, EC has nothing to do with the European Community! In this case, EC stands for Electronically Commutated which basically means it is a fan with a brushless DC motor

Energy savings, convenient control and low noise Cylindrical rotor fans in EC technology

Saving energy is becoming an ever increasingly important topic these days. Especially when it comes
to air-conditioning and ventilation technology, great potential savings can be achieved by using

energyefficient fans

Brushless DC external rotor motor belongs to non-mechanical brush(commutator)DC motor which enforces the winding current commutation through electronic commutator (position sensing, non-position sensing),achieve the speed control function with PAM or PWM control

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

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

Protection: over voltage, over temperature, over current, phase loss detection, communication failures.

The basic interface: 0-10V/PWM, RS485/Modbus, 4-20Ma

The basic parameters of field programmable: Maximum speed, minimum speed, maximum power, maximum current, resonance avoid

1. Can we buy a sample for testing?

Sure, you are welcomed to buy a sample before mass order.

2. if the fans doesn't work well, what shall I do ?

If happens within one year, we will take in charge of the maintenance, or send you a new machine freely.
If after one year, we will supply you the right parts to replace at low price.
