It can be very dangerous to increase the pressure output of your pump. Also, be aware that by creating this “artificial demand”, you are going to increase your consumption costs and run the risk of destroying the compressor pump.īefore adjusting your pressure switch, check to make sure your regulator is adjusted properly. However, you need to be careful not to exceed your equipment’s safety ratings. Maybe you are doing a lot of work with hardwoods or you are working on a project that needs more torque.ĭialing up the pressure switch can help you “cheat” that little extra power from your compressor. Increasing the settings can allow you to get more pressure from your existing machine. Can you turn up the pressure on your compressor? Risks and Dangers This can be handy if you have an oversized compressor and are using it for a job that doesn’t need the added pressure. If you don’t need as much pressure, dialing the switch back can make your compressor more efficient, reducing costs and maintenance. If the pressure builds to a dangerous level, unplug your compressor immediately.īack to Top ▲ Why would you lower the pressure?Įfficiency also comes into play. Maintain a minimum of 20-PSI pressure range between cut-in and cut-out.Ĭaution: It is possible to set the cut-out pressure so high that the compressor doesn’t turn off, and runs until the safety valve engages, the motor burns up, or the tank ruptures. Adjustment is the same: unplug the compressor and turn the set screw one rotation inward to get a higher pressure level and is turned counter-clockwise to get a lower pressure level. Ideally, the cutout pressure point is set about 20-40 psi higher than the cut-in pressure. If you need to make further adjustments, unplug the compressor before doing so to avoid electrical shock.Ĥ. Plug-in the compressor, and, if there is air in the tank, you can use the drain valve to release pressure (or simply attach a blowgun to your compressor and bleed off air) to observe the new cut-in pressures. Turning it counter-clockwise causes it to cut in sooner - at a lower pressure.ģ. Dialing it in causes the compressor to kick in later - at a higher pressure. In most cases, I find the cut-in pressure screw to be closest to the compressor motor. Before setting the cutout pressure point, you need to-first-set the cut-in pressure point. Make sure you have unplugged the air compressor, and remove the cover off the pressure switch.Ģ. When the pressure of the air tank drops to 0.5-0.6mpa, the pressure switch is automatically connected and started.Steps To Adjusting The Air Compressor Pressure Switch:ġ. When the exhaust pressure reaches the rated pressure of 0.7MPa, the compressed air will be automatically shut down under the control of the pressure switch. The compressed air passes through the function of the exhaust valve, the exhaust pipe, the check valve (check valve) and the air storage tank. Precise Air Pressure Regulator G3/8", input 10bar, output 0.1-8bar. During the compression stroke, due to the reduction of the volume of the cylinder, Due to the change of the pressure in the cylinder, the air enters the cylinder through the air filter (muffler) through the intake valve. The compressor is directly driven by the motor, which causes the crankshaft to rotate and the connecting rod to cause the piston to move back and forth, causing the change of cylinder volume. GE-208 adjustable pressure switch is a mechanical controller, the work. In this process, the compressor can rest to protect the air compressor. There is a pressure difference between them. For example, when the compressor starts to turn on, pump air into the air tank, and when the pressure reaches 10bar, the air compressor stops or unloads, When the pressure lows to 7bar, the air compressor starts to start again. When the air compressor is commissioned in the factory, adjust it to the specified pressure according to the customer's needs, and then set a differential pressure. It can make the air compressor stop and rest by adjusting the pressure in the air tank, which has a protective effect on the machine. The Pressure Switches is mainly used to adjust the start and stop state of the air compressor.
