Made a build plan for this new confinement for the filter. Will keep it basic and just use 6mm mdf for the hole build, the fan is not spinning with full throttle thanks to the 6 speed transformer I use for it. So I'm running the 75W 230V motor with half speed with 110V so its pretty quiet, as you seen on the pictures I put asphalt tape over the hole motor and fan chassis to further lower noise and vibration generated by the motor. The only thing left to cut back in noise from it is the whistling noise the air makes passing through the baldes when it compresses. So I will build a new silencer also, the one I got now is the cylindrical one that's in the pic. I think that shape lets the sound waves pass through it undisturbed, I got egg formed insulation but it doesn't seem to affect this whistling noise just humming.
