Compressor Air filter regulator

Dave F. · Nov 22, 2015

Bought a new air compressor, a Quincy it's a large 80 gal. can't remember the c.f.m. at the moment.It is rated 170 psi. I want to get a good filter / pressure regulator any recommendations, my use mainly for air tools & ocasionaly small sand blaster pot & sand blast cabinet & paint gun, but mostly air tools. what brand & model would you recomend
Thanks Dave F.

I've never had an issue with any specific brand, but you need to consider size. If you are going to put a distribution system in you need one at each use point to keep your piping at high pressure. If you're just going to use one hose, you may want a 3/8" regulator so you can use high volumes when you need to, even if it is more than the compressor produces, you can draw down the tank for short periods.

I do not think you can go wrong with Parker.

Steve@Advance · Nov 22, 2015

Any name brand filter will work. Parker has proven to be reliable and has reasonable priced elements. Go with the bigger bowl, bigger filter element. The polycarbonate bowls crack over time, aluminum is better. Haven't had much success with automatic drains, they fail over time, better with a manual drain, mount it where it is easy access, plumb it outside.

I would have just a filter/trap at the compressor. Then put filter/regulators at each point of use as needed. That way you have full pressure throughout the shop.

I would also invest in an auto tank drain, the solenoid valve type with a timer. Add a ball valve and a good size Y strainer ahead of it for easy service.

You'll like that Quincy, they are good compressors.

Short of a solenoid drain valve, I put a street ell in the tank drain and a three ft hydraulic hose to a ball valve. The hydraulic hose holds a lot of condensate and of course will stand water just fine. I crack the valve to let water out occasionally. The hose prevents any possibility of vibration fracture in the external piping.

I will just say the things at Harbor-Freight will annoy you . This is one area where it pays to use quality or your compressor will bleed down and run from the leaking junk. You either pay more for the made in USA or buy it twice when the junk fails or leaks so much you get sick of it.All the teflon tape in the world could not help me.

Like Andy Martin said check your pipe sizes before you buy . Last one I got at loews I was drilling and tapping from 1/2 pipe to 3/4 pipe . Not what I wanted to do with a brand new filter/regulator.

On your new big bad toy......I would turn the pressure down a little. Do you really need 175? Most everything I run is set at 125 and has always been enough. It is harder on the compressor. Just my opinion but. Also I use full pressure at 125 for most things and use the regulators for spray painting and blowing out the lawn sprinkles. That is like 40 pounds. Spraying is around 20. After I use them I unwind the knob on the regulator so the spring will never weaken. Just my habits. Always buy the biggest regulator you can screw on and if you put on a tool oiler every single hose is now junk to use for spray painting. Fish eyes in the paint from the oil. You must have virtually brand new hoses and the best thing is take a trip over to harbor freight and buy a few bubble packs of the disposable air filters that screw onto your spray gun. Work great for me. I have three Emglo units that I love and the big one will run a 20lb sand blaster with a 3/32 tip by itself no sweat. Enjoy

That what is so weird about H-F . The regulator water traps are junk and leak . The water trap to put on the end of the line works great and is a bargain. Harbor -Freight you have to pick and choose or feel the evil.

You get more standard cubic feet in a tank running 175 psi @ pressure switch which means less starts and stops.

We ran some of those things in the lab for thousands of hours above rated pressure when I worked there. I ran a test on a single stage compressor at 175 psi and it lived a long time even though the volumetric efficiency was in the crapper.

David G · Nov 23, 2015

Yes, you are better to run higher pressure in the tank and lines and regulate it out where you need it.

I've used Norgren a lot, but any reputable brand name will do. The bigger the better, so it does not turn into a choke point. Metal is good, plastic.. not so good. And don't just slap it on the tank, run some pipe first so water vapor gets a chance to condense. As suggested, point of use f/r is very good to have as well.

CONGRATULATIONS on getting a GREAT air compressor. Hope you got a real Quincy compressor. SON bought a used Quincy about 4 years ago that was used in a truck stop tire shop along Interstate 80 for 20 years, then used at a body shop for another 20 years, then used at a machine shop for 6 years before SON bought it. 50 years old this year!

Quincy actually recommends sizing their compressors small so they run constantly. Duty cycle is 100%, as in let them run 24-7 for months.

I bought a Porter-Cable coellescing air filter regulator to use on my 7-1/2 HP Porter-Cable 80 gallon 2-stage compressor, has 1/2" NPT inlet/outlets. Got it at Farm & Fleet, think they still sell them.
