– Industrial Extractor Axial Exhaust Ventilation Commercial Air Blower Fan 350mm / 14" (4 Pole) 4650m3/h [Energy Class A++] Black (Heavy Duty Metal Without Speed Control Regulator)

Works perfectly, I replaced a very expensive extractor with this one and works just the same at a quarter of the price

Its a bit loud (air flow noise rather than mechanical noise) but of course it is an extractor fan not a cooling fan so this is to be expected. That said, it moves air at some volume and in my case I wanted to bolt it to a stand and attach it to a 12" flexible ventilation duct to turn it into a portable extraction system to remove dust in rooms during DIY projects and this works a treat (it has a very convenient rim to easily attach the ducting to). Lot cheaper than a purpose built builders extraction unit and it takes up less space.

It does NOT come with a speed controller

Cooking in my kitchen had been very uncomfortable before I installed the Power extractor fan . Now, once it's switched on, cool air rushes in replacing the hot air caused by the cooking. It's made a whole load of difference for me even though it's quite noisy.

Less sound

Installed in Sunbed shop works a treat

Not sure if I was just unlucky but there is something stuck in the motor, possibly a ball bearing. The first time I turned it on it made a very loud rattling noise, annoying after having to wire up a plug. The wiring is a little off putting too, as it’s not standard UK wire colours. Safe to say I will be returning this.

A bit noisy
