Air Compressor set up for a small shed

by Paul

Hello, my name is Paul and I am trying to set up a paint booth in a small 12'X12' shop for painting lures.

My compressor is a 5hp 25 gallon Craftsman oiless compressor.

However, it is very loud! and I would like to build a small room or area for it just outside my shed so that I do not have to deal with as much noise.

Is this doable or can the lines freeze and cause me issues in the winter months?

The compressor currently has a regulator and water trap at the unit.

I was just thinking of running a line directly into the shed after the water seperator and over to my booth. At the end of the line, incorporating another regulator and water trap.

My shed will not be heated all the time...only when I will be painting in it. Would this be an issue?

Any suggestions or advice would be greatly appreciated and helpful before I begin on this project.

Thank you,

Paul Fec

Put a door from the workshop into the insulated compressor shed so heat from the workshop can get to it.

Otherwise, adding a filter at the discharge of the compressor will remove free water but will not remove water vapor that will condense in the lines and freeze once it hits the temperature of a PA winter!

More filters are always better than less as vapor condenses in air lines all the time. The length of the line and numbers of elbows will affect the amount of water. See the pressure drop page for details, as well as reading about the desiccant driers, and the pages on plumbing a compressor that cover all of this already.

That is essentially what my plans were, but only I'm adding a small addition onto the shed for the compressor due to saving the space inside the shed. My biggest concern was for the freezing of the air lines. I plan on adding two filters...One at the compressor and one at the end before my fitting for my airbrush hose. I am also considering another tee and supply between the compressor and the airbrush booth for general use/tire filling/etc.....would you recommend another filter near that supply fitting?

Thank you Bill

Canot be done?
by: Bill

No, I'm not saying that. It depends on how much money you want to throw at the correct solution.

It were me, I'd put a wall around the compressor in the heated part... and draw air in from the outside, as it says on some of the pages.

So Bill, are you saying it cannot be done? I will search the site as well, thank you very much!

Locating compressor is small shed

Hi Paul...

Yes, installing an air compressor in a shed that is unheated, particularly through what could be very cold PA winters, is not good.

Not only will you have a problem with your air lines possibly freezing, your air compressor might not start at all if it's too cold, though I note that yours is oilless, and as such, the motor would not have to deal with frozen oil too.

See the location and installing pages on this site for information about sound deadening. See the pages that refer to water problems for solutions to water in the air lines and to help deal with air lines that move from cold to hot locations.

Answers to pretty much everything you asked are already on the pages on this site. Use the search box on the sitemap page for help in finding them.
