1) I need to operate this at a very low rpm- like 10-20, can this do that? 2) At that speed how noisy would it be?

It is hard to determine that low of an RPM with a foot control. The noise on mine is low.

Possibly a turntable gear motor, very low RPM. Adapt a flex shaft to the output.

Forgot to mention, the case fan is quite loud so I would either replace it with a quiet one or get a simple fan speed controller. This is what i got.

I would definitely look for quieter fan. Scale of 1-10 . 10 being loudest. This fan would be a 7. You can insulate it and make it quieter. There is some really quiet fans out there. Most people use these in attics or in an insulated box. Google it and there is alot of info out there.

You should be able to use a standard on off switch, but you will have no speed control and it will be quite loud.

The amps drop from like 10 to 2.5!it's still going to be 1 1/2 hp,only at a slower speed (less gpm).80% of the time low speed is good.once in a while run it on high to mix water...shock,ect....

Thank's for your Question. Sorry to tell you, but this thing is very loud. It turns at a very high RPM. So it screams.. So, you might want something larger. They don't have to work as hard. Good luck.

You will need a speed controller, they cost about $20. You can also use insulated ducting which will do a good job at reducing the noise, depending on how you have it set up.

There is a significant 60 cycle hum since it is a hefty motor. I wouldn't call it annoying though. If you are chopping something like ice then it will be noisy. Unavoidable in my opinion.

I know exactly what you are making and this should work great. Might possibly be more than what you wish for but if the audible level isn't a concern for you then this will do great. I am using mine to ventilate a foam structured "quiet box" for my camping generator. To get a good idea of the power this fan produces I can tell you that if you sit it on a flat surface and have the air flow being sucked from that flat surface, this fan will need adequate force to be pulled off while running. Hope this helps, its a great fan at a great price. Just don't expect to not hear it.

Yes, it super quiet at the low speed. At the highest speed, it is not super quiet. It is a great fan, however.

There are two speed settings. When set on 2, the higher rpm setting,it's rated at 1400 rpm.Thank youWorldGoodsCorp

RPM unknownI would say light breeze or you will have noise. Subjective answer.Buy it and return it if it doesn't suit your rpm requirements.

Low speed is 600 RPMs, High speed is 12,000 RPs. I have a Maltese and only need to use the low speed on her.

I can not answered correctly, because I bought it for my doughter. But she never complaned about noisy.she told it works perfectly.

It rotates somewhat faster than a full scale turbine, which is about 20 rpm. My best estimate is about 60 rpm - if you need a more exact measurement, I can pull one in from the warehouse and assemble it. We are happy to replace any defective units or those that do not meet expectations.
