    There is no support for forward curved multi-blades centrifugal fan from 133mm-250mm. Other model have the support. And there is no current collector for backward curved impeller centrifugal fan. You need to inform us if you want the support or current collector for fan model, clarify the fan model, specification, air volume and static pressure before placing an order. Forward curved multi-blades centrifugal fan and back curved impeller centrifugal fan, please take note on the air direction

     

    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

     

    Brushless DC motors have been around for many years but there has always been the need for a separate DC power supply. In applications using only an AC supply this introduced added cost and complexity. Then, in 2003, ebm-papst brought out an EC fan with integrated electronics which could be connected directly to an AC mains supply. In addition to performing the commutation, the electronics convert AC to DC and control the fan speed by regulating the power to the motor.

     

    EC motor features reverse polarity protection, locked rotor protection and soft start.

    No additional protection such as contactors are required.

    Can be pre-configured to suit specific sensors and applications, and are supplied standard with 0-10V control input.

    A full range of sensors are available including differential pressure, humidity, temperature, air velocity and pollutant

     

     

    1.How do I know which model I should choose

    Please tell us the fans pressure and ofan and size of fans’ diameter you need. We will study and suggest you the right model.

    2. Can we buy a sample for testing?

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

    3. 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.

     

    Air performance curves

    Our performance curves are tested in test camber according to DIN 24163 and refer to an air density of 1.2kg/M3. Testing conducted with inlet cone in airflow direction A, without protection guard
