Square D Pumptrol Pressure switch for compressed air compressor 9013FHG12J52M1X 95-125 psi With Unloader & On/Off Lever (Paks) 4.6 out of 5 stars 278 $32.90 $ 32 . It would prevent an ac component from exploding but will release refrigerant into the atmosphere and additional contamination to the environment. As air is used and tank pressure drops to a specified ‘cut-in’ setting (approximately 30 PSI below the ‘cut-out’ setting) the contacts close and the motor starts again. When the specified system pressure is reached, a diaphragm inside the pressure switch pushes against a mechanism which forces the electrical contacts apart, breaking the circuit and stopping the motor. Quantity: 2 available / 3 sold. If the pressure switch has a differential adjustment spring, the same principle applies. A pressure switch is a mechanical device that relies on air pressure to control the operation of an electric air compressor. Clockwise will increase the differential and counterclockwise will decrease it. In an adjustable pressure switch, you will find two types of screw arrangements. Air Compressor Pressure Control Switch 4 Ports 95-125 PSI w/0-200 PSI Gauge 150 PSI pop off valve Easy online ordering for the ones who get it done along with 24/7 customer service, free technical support & more. Grainger's got your back. 2 product ratings - MAKITA Air Compressor Pressure Switch Cut off 135 PSI MAC2400 MAC5200 AC700 . When the specified ‘cut-out’ pressure is reached, it forces the contacts apart and shuts down the motor. Free returns. Some of our pressure switches allow you to adjust the top and bottom end settings independently, while others only allow you to adjust the top end setting and the bottom end setting will stay within 25 psi (approximately) of that. Install refrigerant gauges to the refrigerant service valve, found on the large refrigerant line in the … It’s the electric counterpart to the piloted unloader valve which we discussed in a previous blog post. The step-by-step repair guide and video explain how to replace an air compressor pressure switch in less than 45 minutes. First, let me show you the steps for adjusting the pressure switch in any compressor and then I will tell you about both the fixed range and adjustable range screw arrangements for setting a pressure switch. All Rights Reserved. The procedure can be different depending on your air compressor pressure switch type. Air compressor pressure switch with OFF / AUTO selection This is basically an all-in-one solution for small compressors. Easy online ordering for the ones who get it done along with 24/7 customer service, free technical support & more. The pressure switch is an important component on many of our electric models. Reminder. All of the pressure switches used on our air compressors include a pressure switch relief valve which relieves head and line pressure, allowing for easier starts. Wait for the compressor to stop. Caution: Before performing work on any air compressor component, unplug the machine from the power source and drain all pressure from the system. 90 The adjustment spring is used to increase and decrease the cut-in and cut-out pressure settings. Price $152.00. The contacts, which are made from a conductive material (90% silver, 10% nickel), are used to complete the electrical circuit and allow power to the motor. C $36.90. A damaged cut-off switch could prevent an entire ac system from working. We come to your home or office and you can go on with your normal day. If failure of the cut-off switch happens the only safe way out the pressurized refrigerant will have would be through the pressure-relief valve, usually installed on the bottom of the ac compressor.
