For my shop I want to install a air filter system .
I found a fan , witch looks strong enough , but I am not sure how to connect it.
There are 4 wires from the motor and one earth. There is also a capacitor that comes out off the motor.
The fan was previously used for a air heating system as a blower.

On the unit is a label : sonitec SA Nivelles , google gives almost nothing.
The wires are , Red-Black-White and blue .

Ohms :
red-black = 17 Ohm
red-white = 34 Ohm
red-blue = 10 Ohm
black-white = 20 Ohm
black-blue = 10 Ohm
white-blue = 27 Ohm

Can somebody help me out ?
