Can I install a lower psi pressure switch in my Dewalt D55168 air compressor. I don't need it at 200 psi

Compressor pumps slow past 150
by: Bill

If the pressure build past 150 PSI seems to take forever, does it really, or does it just seem so?

If you have actual data that suggests that the compressor is taking longer to fill to cut out than it used to, you may have a compressor maintenance issue.

Why compressors don't build pressure (as normally) is covered on the troubleshooting pages.

Dewalt 55168 200psi comp.

I agree on the 200 psi being plenty.

It seems like it gets up to 150 psi without effort and then bangs the last 50 psi out for what seems like an eternity. It gets rather annoying.

I know it would run more frequently but I think I would be happier.

I have looked around an can't find a good replacement that would fit into the same configuration.

Its made by Devilbiss who also makes compressors.

I cant seem to find that they offer other pressure switches with different cut in/out ranges.

lower pressure
by: Doug in

If you're thinking about this because of all the wasted air (and electricity) after using it for a short time/small job, you could just turn it off manually before it reaches cut-out.

For bigger jobs, just use the regulator.

Install lower pressure switch?

I've had this question a few times, Charlie, and I really don't understand why you would want to.

Your DeWalt 55168 is designed to run within certain pressure parameters... a pressure level at cut in, and a higher pressure level at cut out. That's where the air compressor operates best and most efficiently.

By monkeying with the pressure switch settings to get a lower High pressure cut out will not benefit you.

Why not use the air regulator that comes with the compressor to dial the air pressure in the line to your air tools down to the minimum effective operating pressure the air tools work at? That's where the pressure should be anyway.
