Air Compressor Question

[jakgop21]

I have a older Campbell hausfield 20 gallon 110 v air compressor . It is for home use for air tools,and a nailer . i ran a line to my back yard to have air back there roughly about 55 feet away. Currently i do not have a filter/dryer and the only thing that is acting as a regulator is my pressure switch.

I found a wall mounted 1/4" Compressed Air In Line Moisture / Water Filter Trap & Regulator Combination. 5 micron filter for moisture, 7 -150 psi air regulation .

My question is this good for my system to run occasional air tools? impact, ratchet , tire chuck , blow gun, nailer, grinder, drill , etc.

Thanks

It should do the job, however, remember to change the filter element regularly as per the directions of the manufacturer. When it comes to filter regulator combinations, it’s better you get the filter specs verified by experts online at Compressor World.

Yes it will work, the reg is a bit small for impacts, see how it works but you could get on with just a filter, this little comp really doesn't need a reg.

Is it better to have a separate filter and regulator ?

Also once setup I was told to run about 90 psi is that correct ?

It's good to have a filter / regulator near the tool being used... not in another room or building.

90 PSI... Usually, but it depends on what tool you are using. The tool will usually be marked as to the maximum air pressure.

I took an ASME pressure vessel design class back in the early 1980's and the instructor brought in the aluminum cup off of a paint spray gun, the bottom was inverted (pushed out). He said he forgot to drop the air pressure, and hit it with 175 psi air. That visual has stuck with me throughout the years.

Your second about the location is new to me . How far away should I have the filter /reg from the tool ?

How do you do that i was planning on installing near compressor coming off main source before splitting to 2 different air feeds

If you have this FR in the main line put a QD in the line ahead of it so that you can runn full pressure if you need it. I spent many years using industrial pneumatics and I am a firm believer in running the distribution lines at full pressure and only regulation atthe point of use.

Do this, plumb your regulator with a qd plug on the inlet and a coupling on the out. Then you can put it inline anywhere you have a QD. Put it at the compressor and see what it does. Then move it to the end of the line at the tool and see how it behaves. You might have an AH HA moment.

no neat sig line

Not sure what size the line is... and does it go to a different building in the backyard?

There will be a pressure drop through the tubing / pipe / hose.

If the tubing / pipe / hose is large and fairly straight, the pressure drop may be negligible.

If the tubing / pipe / hose is small with a lot of turns you may be surprised, perhaps even shocked, at the pressure differences.

So you may set the pressure at the compressor to 90 psi... but after running the air through a small line only have 70 psi at the tool.... make sense?

The hose is 1/4"npt just to stay consistent with the pressure switch . It changes to 1/2" for the down tube that goes down the wall .

It is about 55ft away roughly . Both compressor and back line are in the same building . Just came outside of garage ran straight to the copper tubing that came down to quick connect .

I unfortunately already purchased the unit . Due to cost it was cheaper to get an all in one regulator and filter combo .

I will check pressure drop once setup at compressor end and tool
End as mentioned above.
