![]() However, if you’re undertaking these operations at the end of the day regardless, it may make sense to bleed pressure off of the system first, especially if you’ll be testing the cut-in at a lower pressure than you currently operate at. You don’t need to open the drain valve, as the lack of current at the electrical contact will prevent the pneumatic pressure switch from running the compressor pump. Turn off the air compressor and if possible, pull the plug to avoid accidental shocks to yourself, your crew, or any bystanders in the area. Because the pressure switch will control the electrical current to the compressor motor, it’s vital that you follow safety measures, including wearing personal protective equipment. Air Compressor Pressure Switch Adjustments: Precautions + Required Tools Safety PrecautionsĪir compressors often work on an electrical circuit, which makes it important to take appropriate safety precautions. In this article, we’ll take a look at the steps that are taken when you are adjusting your air compressor’s pressure settings at the switch, including appropriate safety precautions to take to prevent an accident, what kind of tools you’ll need to get the job done, and the steps required to make the changes to your air pressure switch. It’s much simpler to change your system’s line pressure, where a pressure regulator is adjusted to adapt the pressure in your feed lines that go to your tools. This is a different process than changing the line pressure for your system and should not be confused. In this situation, being able to adjust your air compressor switch is an important part of operations. Similarly, you may need to adjust the breadth of the pressure range in which your air compressor will operate. These settings are the pressure at which your air compressor switch, a mechanical device, will turn on to increase air pressure or turn off when the higher pressure that is set is reached. However, sometimes you have to replace the switch with a new pressure switch that has been set to different cut-in pressure and cut-out settings. At Advanced Air & Vacuum, we always recommend having a professional look at your manufacturing sector air compressor to see what the system will bear, or if any other upgrades would need to happen before pressure switch adjustment takes place. This is especially important when you’re considering adjusting the higher pressure end of your switch, because the rest of the system may not be rated to higher pressures and turning up the pressure can damage it if the rising pressure doesn’t trip a faulty safety valve and tank pressure gets too high. For the most part, operating within this range, especially the cut-out pressure setting, is the best way to operate your air compressor. The cycle continues as long as the air compressor cut off switch is in use.Your electric air compressor is designed to operate within specific air pressure ranges, with pre-set cut-in pressure and cut-out pressure setting options. As air is used and tank pressure drops to a specified ‘cut-in’ setting (approximately 30 PSI below the ‘cut-off’ setting) the relay contacts close and the motor starts again. When the specified system pressure is reached, a relay will control the electrical contacts apart, breaking the circuit and stopping the motor. When the compressor is plugged into the air compressor system, the motor starts and the air compressor begins to pressurize. Compared with the mechanical switch, it has the characteristics of simple operation, clear display, anti-vibration, and high control accuracy. The air compressor cut-in and air compressor cut off switch can automatically control the relay output according to the pressure in the tubing. Intelligent air compressor pressure switches made by LEFOO pressure control are instruments of pressure measurement, display, and control. A new pressure switch is usually more precise than repairing an old one, while adjustable digital pressure switches give you more convenience when using them. ![]() In pressure switch manufacturer, Picking the right air compressor pressure switches depending on what the air compressing system is. ![]() There are numerous types of lefoo pressure switch for air compressor cut off switch that come on the market.
