💨 Upgraded 95-125 PSI Air Compressor Pressure Switch with Unloader Valve Review

This is a direct replacement for the OEM source Lefoo. My old compressor started running intermittently and tapping that switch kept it running for a while. There are two differences to my original. The pressure solenoid on the side is straight and not at right angles so I had to reposition the valve to get it out. The original had strain relief on the power cords that went on each side, while this one only has protective shields. The cable to the motor doesn't need a strain relief like the…

Just installed on my 1985 Craftsman 919.176311 12 Gallon 1 HP Compressor. Really close to the original Furnas Electric CAC-4220-1 switch. The original discharge tube was bolted on and even had the same thread size as the nut and no bending of the tube was required. Here's what you need to do: Purchase the shortest 1/4NPT nipple you can find for redundant mounting. Unscrew the original wire tabs from the Furnas switch and screw them onto the Lefoo. Pull the rubber cone plugs out of the Lefoo…

I have a 125psi compressor that stopped turning on when the pressure dropped to a low of 95. I re-roofed a garage. Such a pain! Bought and delivered on the third day. I took a photo of the old ESC's wiring before I removed it so I know where the power cord and motor wires are. It took me a while to replace the old one because I had a leak on several air line threads. I removed the air ducts, cleaned the threads and wrapped them with new Teflon tape. Then I turned on the controller, which took…

MY FIX WORKS GREAT. but I wouldn't recommend doing what I did unless you are familiar with pneumatic and electrical systems (a safety concern). but it works fine. When I first started looking for an OEM replacement pressure switch for my porter 150 psi 6 gal cable. Pancake compressor, I've seen that while it was only about $12 at several locations, it was also ordered from the factory. So the price was a moot point. With experience in instrument building and repairing, I decided to replace the…
