I have a DeVelbliss model PRFB5020VP-1 and the discharge line from the head of the compressor to the air tank valve snapped. I have been trying in vane to find a way to fix it after paying $150 for it. I ordered nylon pneumatic easy push hose and connections, but I have been unable to find the brass fittings for the head and where it connects to the pressure valve on the top of the tank. Do you have any suggestions on where I might find these or a work around so I can get this compressor up and working?
I have a Craftsman air compressor Model No. 919.152813 that utilizes an A.O. Smith AC motor S# K56A28B23 that starts up but under pressure stalls the motor resulting in a humming sound.
It build to about 25 psi before the motor bogs down and stalls.
I have the compressor plugged into 220v 4 prong outlet on it’s own circuit with a 30amp breaker. I’m using a 3ft dry cord from home depot with the neutral wire capped off. I have replaced the pressure switch/unloader valve, the check valve, and both valve plate assemblies. I checked both capacitors and visual they don’t seem to be bad. Can anyone help me out?
hi can you please help .have not got a clue what make hoping some one will know .my problem is the motor stalls at 3 bar the actual compressor jams ..let some air out and it’s possible to restart ..
My Husky compressor will turn on and charge up to 150 psi. Once I start to use it and get it down to 90 psi my compressor will not recharge the air it needs to keep going. What do you think is going on? I’ve had to deplete it completely and then restart the compressor for it to fill back up again.
Hi.. .I have a 60 gallon Kobalt compressor that is having problems…
Pressure switch and unloader valve are new.
Symptoms:
It starts fine and although gauge does not read pressure in the tank, it seems to be building some.
When it reach 20 you can feel the pump starts to work harder and when it gets to 30 PSI, the motor cant push it anymore and the velt stars to slip…
When turning it off… all the ir is being bleed through the unloader valve until everything is empty.
Would you think a faulty check valve could be the problem?
Hello, I’m a uni student and need some guidance for my grad project. Is it possible to use a compressor or pump to pull carbon dioxide gas from an incinerator (after cooling process) and then inject that gas it into a tank? Any help is welcome, thank you!
I have an old MF Master Elite Compressor. I’m in search of 2 tiny screws that secure the pressure gauge cover to the gauge itself or a completely new gauge. Also, the brass valve (see photo) leaks when I shut off the compressor. I don’t know what it is and was hoping someone could identify it – and possibly know where to get a new one.
Thank you,

This might be a dumb question but I cannot find any information about this online. My replacement capacitors are slightly smaller than the originals which cause them to be a little loose under the cover housing. If the caps vibrate and the 2 spade connectors touch the metal cover housing, can I be electrocuted? My spade connectors are not covered. Are they suppose to have a protective cover or something?
I just purchased and installed a 034 Sanborn pressure switch on my compressor. When I turn the switch to the off position, the unloader valve stays open and leaks all of the pressure out of the tank. Is there an adjustment for this?
I picked up an old air compressor pump, tank and motor last night. Pump is a Buckeye ball bearing model v20-6c serial 6266. im looking for any info i can get on this pump. Any help would be greatly appreciated.
thanks, mike
BRA7180V (7.5HP/80 gallon/175psi) air compressor. What is the little lever on the backside of the pressure switch box? I just picked up the air compressor and had my electrician hook everything up. It works great but I’m puzzled about the little lever on the back of the pressure switch box. It can be moved to the vertical or horizontal position–but I’m hesitant to mess with it. I do notice the pressure switch shuts off at 150psi and I believe mine is rated to 175psi. Any guidance since I don’t have a manual?
Does my twin cylinder oil free Pro Air II 6 hp 60 gal. made by DeVilbis need regular lubing? It’s in a soundproof box, but starting to get louder. Cant get to it unless I dismantle the box, so am asking for specific places it might need lubricant. What oil is recommended for that?
Thanks!
I have a Sullivan d1850 air compressor while using it it suddenly lost air pressure and the motor revved up freely
I have a 2003 Porter-Cable consumer compressor (model CPF234005-2). The regulator adjustment seems to have frozen, at around 50 psi and I cannot change it to get air gun pressures. The tank gets to full pressure. As it happened, my 18 ga nailer also failed, so I purchased a combo kit. The regulator seems to be part and parcel of the manifold, and a replacement seems to be over $100. Is there a cheaper and safe way to rig a regulator, gauge and outlet so I can use this as a spare compressor?
Many Thanks
David
