Husky tank rated at 150 psi but shuts of at 135psi Normal?
PRV and unloader valve on Husky air compressor
I have a 26 gallon 150 psi oil less compressor. The tank builds pressure up to 135 or 130 and shuts of is this normal. Also their is a little lever that pushes a pin down and release the all the air if the compressor is off. also on auto but turns motor back on once it reaches 100 psi is this normal. picture of lever attached just bought it kinda of lost
Howdy... if there's anybody that needs to read the Home Compressor cover to cover, it may be you. :-)
When you say the tank is rated for 150 PSI, do you mean the plate on it says maximum pressure 150 PSI?
The tank pressure has no bearing on the normal cut in and cut out pressure settings of the air compressor.
That yours is cutting in at 100 PSI and cutting back out at 130 PSI is normal.
The unloader valve opens when the compressor stops. If all the air bleeds out of the tank when that happens, that typically means your tank check valve has failed.
Essentially, everything you need to know about your air compressor is on the pages of this site. The eBook simply puts it all in one place.
13 gallon, 1.7 HP Husky continually runs
by Chris Hardwick
My 13 gallon, 1.7 HP Husky continually runs. I replace the valve on bottom of tank that took care of a leak.
Compressor no cycling off after it reaches desired tank pressure
Chris, if your air compressor runs, builds pressure normally, and then the air pressure in the tank bypasses the normal air compressor cut out setting, and continues to run, almost always, this indicates a failed pressure switch.
Air compressor shuts off at 60 psi
I have a Husky 32 gallon, 110v, 1.8 hp, 5.5 hp peak Air compressor. It fills to 60 psi and shuts off and will not turn back on for 20 minutes.
When I drain the pressure, towards the end, it reads 0 psi on the tank guage but pressure is still being released.
The other guage, used to measure the pressure in the hose does not register anything.
I suspect it could be the pressure sensor inside of the tank but this is just somewhat of an educated guess.
Also, this is a fairly new machine. No dust, dirt or any dirty greasy things located anywhere on the machine.
Any suggestions as to whats causing this? The guy I bought it from said he replaced the pressure switch, which is what leads me to assume its the sensor inside the tank.
Hi Brian. Thanks for writing in.
I am a bit puzzled by your compressor specs... "Husky 32 gallon, 110v, 1.8 hp, 5.5 hp peak Air compressor." I don't think your compressor can be both 1.8 HP and 5.5 HP, and I don't believe you can run a 5.5 HP motor from a 120 VAC supply line.
Having said that, I also am a bit confused about the sensor in the tank? To the best of my knowledge, no compressor has a sensor in the tank. The tank pressure is read both by the external gauge, to show us what the tank pressure is, and by the mechanism of the pressure switch, that reacts to the tank pressure, and turns on the motor when the pressure drops to the cut in level, and turns off the motor when the pressure in the tank gets to the cut out pressure level.
You say your compressor... "It fills to 60 psi and shuts off and will not turn back on for 20 minutes." In this 20 minute time frame, are you using any air, or is the air in the tank set at 60 PSI, and then, 20 minutes later, the compressor starts again?
I believe that 60 PSI is too low to be a normal cut in pressure level, and also way to low for the compressor to shut off.
The symptoms suggest to me that it is still the pressure switch that is the problem, either a bum switch, one that's wired incorrectly, or one that has wrong settings.
When you say you drain the pressure, towards the end, it reads 0 psi on the tank gauge but pressure is still being released, how long does this last? Your tank drain may have a small obstruction that slows the air flow near zero pressure, but since the gauge likely has a 0-5 PSI accuracy range, it could show zero and still have some little air draining for a few seconds.
Husky 6 gallon portable - my air pressure does not exceed 30 PSI
by Ron Utley
(Payson, Arizona, USA)
My four year old Husky 6 gallon portable, model H1506F has a high volume leak near the ???unloader valve???. This is where the electrical incoming lines and the gauge's maniford are located. The leak is between the top of this ???relay??? device and the roof of the housing of the compressor.
Is this relay device one assembly or can it be separated for individual replacement parts?
I only removed the compressor housing and started compressor to look for leaks. No other parts were removed.
Sorry that I don't have any pictures to send.
Thank you for any help that you have, Ron utley
Ron, start with going to the Valves Page, and click the link to the Check Valves Page.
From your description, it sounds to me like your check valve may be stuck in an open position, or debris is blocking the operation.
This would be my first step in resolving your compressor problem.
