Husky air compressor volume for sprinklers

by Aron
(Minnesota)

Hi Bill,


I currently have a 26 gallon Husky air compressor that is rated at 5.0 cfm at 40 psi and 4.0 cfm at 90 psi. For most of my projects this works just fine.

However, I recently began wanting to service and blow out my sprinkler system that I designed and installed a few years ago. I'm finding that I don't quite have the volume to blow out the zones as well as I would like.

I also don't have the $2K to buy a new compressor that has 15-20 cfm at say 65-70 psi so I'm in search of an alternative.

If I were to add another 26 gallon tank to my existing compressor, would that give me more volume and if so, how would I determine what that cfm is?

I do realize that by doing this, it would take my compressor longer to recharge but on the flip side, it would take longer for it to run out as well. Do you think this is a viable option or should I keep using the one tank and buy a bigger motor?

The formula is there

Aron, see the sprinkling page.

The formula for figuring out the amount of air you need is there for you.

Well enough to blow them out. Ideally 10-20 cfm. Do u think adding another 26 gallon tank would achieve what im seeking?

Volume for sprinklers

No question that another tank will give you greater volume.

How much do you need?

If you see the pages on this site about blowing out sprinklers, the answer is there for you.

For intermittent seasonal use, it may not make any sense to acquire a larger compressor just for that.

question about 32 Gal 660800AJ

I have a 32 Gal 660800AJ. After compressor fills to set pressure, and after pressure is used down, it will not come back on. Wonder if it is the check valve. Thank you for advice.

Husky compressor won't restart
by: Bill

Not an unusual problem, Willy.

It would be good to know if the unloader valve is working.

Empty the tank, start the compressor, let it run up to cut out pressure, and then monitor the unloader as the compressor shuts off to be sure it works.

Let us know as a comment.

WHAT TYPE OF PAINT GUN CAN I USE WITH A HUSKY 1.5 HP?

155 PSI MAXI,3.4 SCFM@40PSI 2.5 SCFM@90PSI
I NEED TO PAINT BASEBOARDS AND DOORFRAMES

Really quite a simple answer. You need to get a paint gun that will handle the viscosity of the paint you plan on using, with an air and pressure demand that is equal to or less than the output of your air compressor.

If you get a paint gun that uses 40 PSI at 35 CFM to paint with it won't work properly since you say your compressor puts out 3.4 CFM at 40 PSI.

Note that I use CFM for after compressor air flow measure, and SCFM for the measurement of free, uncompressed air.

Read the pages on SIZING on this site for more details.

Cheers,

Bill

Mike, this has been addressed in detail on the troubleshooting page no air out of hose.
