Steps to Air Compressor Pressure Switch Adjustment If you’re rehabbing your air system, you may want to include Teflon tape if you’re replacing piping with threaded connections or need to replace gauges. DO NOT spray flammable liquids on the pressure switch while it is hooked up to an electrical current! Similarly, a bit of sandpaper or steel wool is handy if you need to clean up the switch contacts due to corrosion. Depending on how long it has been since you’ve adjusted the pressure switch, you may need to use dielectric grease or an electrical solvent to get the set screw to move. If the compressor and lighting in the area are hardwired into a breaker, you’ll need to throw the breaker, so make sure you tape it off and have alternative lighting available to be able to see what you’re doing. You’ll need a screwdriver or wrench, depending on the type of air pressure switch that you have on your compressor. Generally speaking, the adjustment process needs very little in terms of tools and materials. Similarly, if the drain water from your drain valve is rusty, you may want to have your pressure tank inspected before adjusting the pressure up, as that can be a sign of corrosion within the tank. You may also want to inspect the pressure switch relief valve so that you know that it will blow off extra pressure instead of causing a blow-out if you turn the maximum pressure too high. 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. 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.
