SUPPLY LINE OUT OF COMPRESSOR BLOWING OUT

by JAVIER
(CAGUAS,PUERTO RICO)

I HAVE AN 150 PSI 60 GALLON UPRIGHT COMPRESSOR. THE SUPPLY LINE LEADING OUT OF THE COMPRESSOR KEEPS BLOWING UP SENDING FITTINGS AND THE SUPPLY LINE EVERYWHERE. I USE 1/2" O.D. PLASTIC LINE AND AND PLASTIC QUICK CONNECT FITTINGS. THIS HAS NEVER HAPPENED BEFORE.

Javier, do I understand correctly that you have a 1/2" plastic air line plugged in to an instant fitting on the discharge line from the air compressor?

When you say plastic, do you mean polyethylene, or do you mean PVC?

If you are using PVC as an air line... stop. PVC does not have the pressure capacity for compressed air.

I suggest you change the plastic lines to rubber/vinyl hose that is made for compressed air.

If I have it wrong, please post a comment here to help me better understand your compressor plumbing problem.

Cheers,

Bill

stinky air lines?

I have a funny smell in my air.

I have checked the air coming out of the compressor and it seems fine.

I think the problem is in the lines. Is there a way to clean out the lines (soapy water, simple green) or do I need to replace the lines?

The compressed air that comes out of an air compressor is likely filthy, may have mold, dust, water vapor and free water, so that the inside of the hose might be a mold paradise, and compressed air passing through those lines can pick up foul odors.

Having said that, you are not supposed to breathe air coming out of a compressor. I wonder what your shop size is like (really small?) if you can smell the compressed air.

What are your air lines made of? If they are rubber vinyl hose, and you feel it worthwhile, then sure, rinse them out. Maybe use an ounce of bleach in a gallon of water or some such, let the entire air line sit in a bucket of water with bleach, and make sure all the air in the lines is out so the whole hose gets rinsed.

Maybe vinegar and water...? I don't know, since I am no expert on cleaning out the inside of air lines.

Or, replace your air lines with industrial polyethylene tubing which is fairly inexpensive, or get new hose if the problem is really bad and you have the budget.

Anyone else have some ideas for this questioner?

Thanks,

Bill

If we use 3 machines then Air compressor air get divided?

We have one production line which uses compressed air of 7HP. We use 10HP 300 Ltrs air compressor? but i want to ask whether the compressed air is getting divided?

Hello Girish.

Compressed air will always flow from high pressure to low, and take the fastest path as it tries to get back to atmosphere pressure levels.

If you have machinery plumbed in series from the air compressor, and the first machine in the sequence uses more air, then the bulk of the compressed air will flow to that machine.

If the first machine uses up as much air as the compressor can produce, then no air, or very little, will flow further down the line to the other equipment.

This is why you want to plumb your air mains in a ring.

Please visit the link "Plumbing" from the nav bar, and read all these pages, for much more information on plumbing your plant.

Cheers,

Bill
