Fan rotation Gardner Denver VS 75

Yeah, that does seem strange.

But I guess that's why they say to check it...

Thank you for the info Mr. Doug in sd.ca

I found the problem. The cooling fan motor rotation is going in reverse. yes the compressor is new and commissioning and start-up is undergoing. i am surprised that the phase sequence of the main motor and ventilator fan motor are not the same. main motor rotation is correct in start-up.(maybe installation error by GD) But GD compressor is the best. I got 2 units ESM 75 for 6 years now (24 hours continuous running) with out break down and No single problem at all.

Hard to say.

G-D soesn't make a VS 75, as far as I can tell.

But if it's new, it should be under warranty.

Still, generally, do you have the right amount of fluid in it?

Is the radiator working?

The fan(s)?

Filters clean?
