Questions and Answers for Powermate 105 - 135 psi Pressure Switch

A:  Yes, this 034-0226RP pressure switch can be used with either a 120 volt or 240 volt operation. It is factory preset to kick on at 105 PSI and kick off at 135 PSI. The Full Load Amperage rating is 26 amps and the Locked Rotor Amperage rating is 156 amps.

A:  Yes, it can be used for 110 or 220, but you gotta know what you are doing with wiring to set it up. Terminals are marked for load and line.

A:  Yes that’s what it is made for my compressor is 4 horse 60 gal

A:  yes

A:  This pressure switch has 4 ports.

A:  Yes, 4 ports. Mine was installed with 1st to the tank, 2nd to the gauge, 3rd to the pressure relief, and the 4th was capped because I have a 60gal tank with a large outlet on the side of the tank.

A:  As long as you have a1/4” npt outlet hole on the tank.

A:  WAITING FOR ANS.

A:  Yes. As long as the pressure range lines up similar to the old one. Pressure switches have a specific range that they are set to and cannot be adjusted.

A:  Clip it close to the existing, or look for set screw on old switch and remove the old fitting, it is a push on fitting with locking jaws. Be sure to round the hose when pushing back in.

A:  There is a collar on the fitting where the tub is inserted, push the tube into the fitting, then press the collar into the fitting, and the tube should release. Hopefully someone didn’t add glue when the installed it last time.

A:  Please call technical support line at 888.895.4549 for assistance

A:  I had the same problem my original switch the problem was a bad check valve on the tank it was leaking once the pressure is up to cut out the switch just releases the pressure between it and the pump should be just short blast

A:  The issue is not a defective pressure switch, the issue is the one way check vlv that holds the air in the tank on your air compressor. When the air compressor builds up to the kick out pressure & shuts off, air should come out of the bleeder vlv on the pressure switch for a few seconds & then stop draining. This is relieving the head pressure off of the pump. The one way check vlv in the top of the tank (or in the manifold asy, depending on the style) should hold the air in the tank. Since your unit is draining down to the kick in pressure, that indicates an issue with the check vlv. Pls feel free to contact us at 888 895 4549 if you have further questions.

A:  Your switch is not the defective part. Your tank has a check valve, and that check valve is leaking the pressure out of the tank. The check valve keeps pressure in the tank, and you switch unloads the pressure in the pipe between the pump and said check valve, so when it restarts, the pump can spin up to speed more easily.

A:  May take a little re-piping but its pretty universal

A:  Unfortunately we are not familiar with the Central Pneumatic compressor. The 034-0226RP kicks in at 105 psi & kicks out at 135 psi The FLA Rating is 26A - 240V, LRA rating is 156A-240V. If the specifications are the same as the pressure switch on your model, it should work as a replacement.

A:  STEP AWAY FROM THE COMPRESSOR! RISK OF FIRE/iNJURY/DEATH In all seriousness, if you are mot confident doing the wiring, you shouldn’t be doing it. There are risks and hazards associated with incorrectly instead wiring.

A:  I didn't have instructions that detailed. Take pictures mark your wires correspondingly, it's not that difficult. Oh yeah unplug it first or disconnect the power (DUH)

A:  The markings on this pressure switch are LINE (incoming power) and MOTOR, (interconnect cord from the motor to the switch). This switch does not have a positive or negative. Your incoming power attaches to the TOP connections marked LINE, the interconnect cord from the motor connects to the BOTTOM connections marked MOTOR. Thank you.

A:  No, it is not included.

A:  Yes, it has an unloaded valve that uses a push-to-connect style small black plastic tube.

A:  Yes it has the unloader valve. I purchased this FOR the unloader valve which had gone bad on mine.

A:  This switch is adjustable. They sell different pressure rated switches, so they may have one that matches your pressures exactly right out of the box.

A:  This pressure switch we do not recommend for you unit. If you call our technical support line at 888.895.4549 we can see if there is one we can offer to you that might work after we get a few more details for you.

A:  As long as you equal or go below your max pressure then you should be okay. I also believe you can adjust the max pressure. similar to a water pump pressure switch.

A:  All of our pressure switches include the bleeder vlv, it will not include the copper tube or any other components.

A:  My compressor is a 2005 Husky, and uses a black plastic tube to release head pressure when it shuts off. Most of the time the plastic tube and copper tube are different dimensions. You may need to a different switch, or switch your copper tube to the plastic tube (and of course the fitting on the othe rend of the tube.
