Husky Compressor /Adding an extra tank

by Al

I just purchased a Husky 6 gallon pancake air compressor delivering 2.5 scfm @ 90psi,1.5hp. I tried it out on my 1/2 drive impact gun and I was able to loose lug nuts with no problem, but by the 4 lug the compressor started up again. My impact gun is rated at 4.2cfm at load. I was wondering if this compressor was good match for my impact gun. The compressor manual or box doesn't specify its cfm. Also I wanted to add a portable air tank as aux tank to expand my storage capacity. I was looking at adding maybe an 11 gallon tank, but I noticed that most tanks say 125psi max, and only found a 5 gallon tank rated at 135psi.My compressor runs at 135 psi. I wanted to know if I could use the 125psi tank or would that be dangerous, and just use the 5 gallon rated at 135psi.This setup which I have will be used occasionally when working on my car (DIY).I've asked a great deal, your feedback will be appreciated.

Hi Al:

A lot of good questions, and all of them are answered if you want to take the time to wander the website and find the pages that apply to them. ebook The Home Compressor will be released end of this week, and it answers all of the questions in one book, making it easier to find the answers.

Any air compressor can run any air tool. With some high demand air tools, the tool run time will be measured in seconds though, due to the air compressor being too small to supply the high demand tool.

If your need is to do more work with an air tool without waiting for the compressor to catch up, you need a bigger compressor. Or, your small one will work fine, you will just have to wait for the air to catch up.

Adding a tank will help improving your tool run time. Here is info on that.

I am surprised that the add-on air tanks you have found are only rated for 125 PSI. Find an industrial compressor shop to find ones with higher pressure rating. You can find them rated for up to 1,000's of pounds of pressure. If a tank is specced for 125 PSI, do not put 135 PSI in it. You are only asking for trouble.

I had pretty much the same question. Thank you for answering my query too Bilal.

compressor capacity

Hi I read the above comments and agree a 2 nd tank will artificially extend tool run time some what.

the best is to get a compressor rated to supply your tool. If your tool uses 4.2 CFm then get a compressor rated for 5 cfm minimum or greater is better. At 5 CFm the compressor will almost be running constantly when you are using your tool.

You should be able to contact the manufacturer about CFM ratings for compressors. Any reputable compressor should have CFm listed on it at a given pressure.

Basically your current compressro is NOT sufficient to run an air tool that uses 4.2 CFm if it puts out only 2.3 CFM. end of story.

My friend also bought a husky that is a 60 gallon that supplies 10.2 CFM at 90 PSI.

I hope my feed back helps.

Husky 3 Gallon Trim Plus won't start...

by Mel
(Honolulu, Hawaii)

Husky 3 Gallon Trim Plus won't start... about a year old with very light use, probably 7-10 hours total.

Power switch lights up but compressors doesn't start up. It makes doesn't make a sound, there is no humming.

Power source is fine and has not been a problem in the past.

Bill says...

Mel, thanks for the info about the power supply. It's often that that causes the problem. Since yours is clean, and you are not using an extension cord (which causes problems too) then, have you drained the tank to zero PSI with the compressor unplugged?

If not, do that. If you drain it and plug it in and it starts, it could be the unloader valve.

If still nothing, can you put a multi-meter on the line from the switch to the motor to see if power is flowing, with the tank empty of air to be sure that the pressure switch has tripped to on?

If no power is flowing it's likely the switch.

Post a comment here with developments, would you?

Husky tf2912 compressor overloads?

by Colin

Husky tf2912 compressor (Photo:

Husky tf2912 compressor (Photo:

my compressor spins freely but seems to be binding and causing the motor to overload and trip the breaker on the compressor. there is a metallic squeek as it compresses. oil level is good and clean.

ideas before i pull it apart?
Lots of ideas Colin. If any are good is the question!

You checked the belt alignment, I'm sure, and that the air compressor belt has the proper tension?

If so, then bleed the tank down, then pull the line from the pump to the tank. Start the compressor. Any change?

If it runs without problems then I would suspect that the tank check valve may be an issue, and disassembling and cleaning of that would be in order.

If the squeaking continues and the compressor motor overload continues, then I would be looking at the pump itself.

That is if the squeaking is coming from the pump head area and not the motor.

Any results?

I isolated the pump from the tank and it seemed to run fine. I removed the check valve and serviced it and put it all back together and it overloaded again. I will try using a new check valve next. I also noticed that there seemed to be excessive vibration in the belt before the motor overloads. Coud the bearings in the motor or crankshaft be going out? I also noticed that there isnt squeaking anymore since the check valve was addressed.

Husky compressor H1820F will not build pressure and not stop running



it started by billing pressure and not stop running a sounding louder. now its don't stop running and don't bill pressure but stop running when i pull the pressure switch off.
In order the for the compressor to stop automatically, the pressure in the tank must reach the cut out pressure setting of the pressure switch.

Start by looking at the troubleshooting section, and follow the link to the page about why air compressors run but don't build pressure.

Have a look at the checks you can do, then add a comment here with what you found.
