One of several important components of an air compressor is the pneumatic-regulator unit. When you get a completely new air compressor that is often used in handheld pneumatic or air tools, a filter-regulator device is already mounted on it. Typically, many bargain air compressors only mount an air-regulator without the filter to cut cost, however in certain reputable brands like IngersollRand compressor. They are actually outfitted with modular air filter-regulator device as normal accessory.

All air-driven devices including pneumatic actuators, valves and air-tools maintain a preferred working pressure to work and to function appropriately. Too small will cause them to not work properly or stop operating, too high pressure will cause the gasket seal to burst and leak. It's necessary to establish the pressure just before hooking up your preferred air-tools, if you unintentionally link a tool that meant to have 85 psi to a 200 psi outlet it can be really deadly and may explode or damage the tool itself.

This is where the compressor regulator will come into action. The air-regulator maintains the pre-specified pressure before proceeding to the system. If the pressure from the compressor tank increases the air regulator will still keep the predetermined pressure. The air regulator can only stop the air pressure from exceeding the ideal pressure however it can't compensate it if the pressure from the air tank loses down below the desired pressure. Just in case the pressure from the second side grows, it has a built-in release valve that enables it to bleed the unwanted pressure up to the point it reaches the set pressure. It has a huge knob on top of it that can be turn to change the pressure output.

A pressure gauge is normally provided to keep track of the output pressure. Without the gauge it will be impossible to adjust the regulator unit since that you have no way of knowing just how much pressure is present on the secondary side. In some compressor equipments you will find 2 sets of gauge that is for the input and the secondary side.

In case you buy a regulator component, you should be aware of the capacity of the regulator you want to buy. The size is designated by the flow rate capacity. As the flow rate capacity raises the port size also increases, it is actually directly proportional to one another. So, you can also apply the port size as the basis of the regulator device sizing. For example, if your present regulator component has a " port, then you should purchase a " regulator component. The regulator device is not commonly offered in most hardware stores.

You can perhaps obtain them in appliance stores who sell air compressors. Some certain suppliers also offers them, like SMC who markets pneumatic valves, actuators and compressor components like filter, regulator, air-dryer, main line filter and after coolers. Other pneumatic providers for example Festo, Bosh, CKD and Bimba also manufacture them.
