I just bought 2 of these 600CFM inline fans to move air from the top of my paint booth in my garage, through two home furnace filters to stop any particles than outside. My old ones were starting to get old and clogged up, I guess I got the wrong CFM as last time and my new ones are blowing too fast. I unfortunately cannot return them


Is there a way to run them at a slower speed? They are 110V

Think lamp dimmer but for electric motors.

Also, why not just stick some filters before the fans so they don't clog up.

These types of fan are normally speed controllable. There are different types of controller.

The ones I've seen fitted before now are normally similar to a dimmer switch or there are some that have 5 steps slow to fast.

Stand alone speed controllers however can often cost as much or more than the fan itself.

A cheaper alternative might be to install a blast gate or single blade damper to restrict the airflow.

How would I make that work.


I put new paper smoke detector covers over the inlet every time I paint. I forgot to add that
>>
>>925553
I don't know much about that. Would you mind posting a link so I know what we're talking about. I guess it's not as simple as wiring a dimming switch to the power cord?
>>
>>925560
It could very well be if your fan doesn't use a starting capacitor.

You could even wire an E27 socket (or similar) in series with the Line and just stick a incandecent bulb in there that'll limit the current to the motor enough to slow it down to your liking. Also it'll give you some light.

Good idea. Thanks

Think this will work?

More than likely. You may find you'd benefit from having one for each fan however.
>>
>>925636
Ok. Thank you, I'll fallow up if this is still open when it comes in. Ordering them now
>>
>>925548

I doubt you care, but there are very specific code requirements for wiring in paint booths.
Just as an example, there needs to be an interlock between the spraying equipment and the ventilation system.

Good luck regardless.
>>
>>925642
I did not know that, I'm not a commercial painter though.
>>
I found that slapping a Harbor Freight router speed controller on most anything works well.

>>925642
Only if you live in an area where such codes even exist.
>>
>>925548
if you have a variac, try underpowering them. Dunno if that will affect their life cycle, tho (it shouldn't)
