Review on 💨 Upgraded 95-125 PSI Air Compressor Pressure Switch with Unloader Valve by Chris Quinto

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 stock "fixed on/off" switch with a push button switch that I could adjust and a converter with a built in "auto-off" switch . -in. (This is quite common with pressure switches). Luckily I found this well-known pushbutton switch design on the Revain site; LF10-1H. This switch is a double pole, two position, pneumatically operated switch. The OEM switch for this compressor is simpler; a "single pole, unidirectional" switch connected "in series" with the motor winding. Most importantly, the pressure on and off points are adjustable on the new switch. While the OEM pressure switch for this Porter cable compressor was set to turn on at 125psi and turn off at 150psi (which intimidates me a little), I didn't need that high pressure (don't use it for a nail gun, etc.) And to be honest, it made me uncomfortable when it worked at such a long distance for so long. Small "oil-free" compressors get hot for a long time. And I have other more commercial departments that I trust more; works for a long time. With this pressure switch I was able to set it to turn on at 90psi and turn off at 100psi. While the compressor has its own on/off switch, the LF10-1H has its own built-in "auto or off” switch and relief valve. Both are good "redundant" safety features in combination with a compressor relief valve and an electrical switch. I will post a short video showing how I physically connected the switch to my compressor and showing the wiring that goes to the pressure control switch. I completely removed the factory defective pressure sensor and simply connected the wires going through the switch to the motor coil. I also bought a foot of high pressure hose to replace the line from the regulator manifold which now extends outside the compressor to the switch housing. I have already used a compressor in my workshop to inflate/clean and inflate tires quickly. It works great and I saved money and also upgraded the pressure switch for this compressor. This is a robust design that can be used on a range of small compressors.
