Why use a compressed air regulator?

If you buy a “do-it-yourself” type air compressor, or if you buy any type of air compressor for that matter, check to make sure that it comes with an Air Regulator. If not, purchase one. You will be glad you did!

An air regulator is a gadget that brings down the downstream air pressure. Downstream air is that the air that’s moving from the regulator towards your application.

Compressed air will flow from the compressor reservoir into the air regulator (this supply is named upstream air) and thru a system of an internal diaphragm and springs, the regulator will maintain a continuing downstream air pressure level, despite changes within the upstream supply pressure from the tank.

Recognize that you simply can only use a compressed air regulator to extend the downstream air pressure up to the amount of the upstream supply air pressure. An air regulator won’t enable you to “dial up” the downstream air pressure above the upstream level.

However, if you can figure out how to do that, do let me know, and we’ll both get rich! ;-}

You will want to set the downstream air pressure from your regulator at a pressure level that’s below the lowest air pressure which will be incoming from your air compressor. Here’s why.

The compressor maximum pressure point is that the pressure level inside the compressor receiver at which the compressor shuts itself off. This is additionally alluded to as the “cut out” pressure.

At the point when the cut out pressure is reached, the compressor stops compressing air. When you start to utilize compressed air from the compressor tank, the pressure inside starts to drop, and eventually the compressor will start again. This is the “cut in” pressure point.

As a result, your application, be it an air tool or an air brush, will “see” varying pressures from the tank because the compressor cycles on and off between the two set points.

For most applications, a varying air pressure supply isn’t satisfactory and it’s particularly problematical for people that use compressed air to paint . Despite your best efforts with the air brush, if the availability air pressure is consistently changing, so too will the standard of your work.

This brings us back to the why you’ll always want to own an air regulator installed in the line between the compressor and your application.

If you set the downstream air pressure at a pressure level BELOW the cut in pressure level of the air compressor, in theory, the air pressure to your application should never change. As the air compressor goes through its normal cut-in and cut-out cycle your air regulator ensures that your downstream device will see a gentle , non-fluctuating, supply of compressed air.

This is theoretical only, unfortunately. If your application consumes more compressed air than your compressor can generate, although you’ve got set your air regulator at a “safe” level, eventually the air pressure from the tank will fall below the amount your regulator is about for, and therefore the downstream device will see a steadily diminishing air pressure supply too; this although your compressor may have cut-in, and is attempting urgently to develop a supply of compressed air inside the tank.

This is why you really want to know how much air you need for your application to ensure that your air compressor has enough capacity to oversupply your needs. Check out details of this at ABOUT-air-compressors. com!

Know that air pressure regulators associate with different levels of accuracy with the least accurate being, as you would possibly guess, the least expensive.

Most common purpose compressed air regulators will have an precision of 3-5 PSI, which means that the particular air pressure that your device is being supplied through the regulator will vary with in that range, despite what it says on the gauge.

If you would like more accuracy, choose a precision regulator, and depending on the manufacturer, you’ll be ready to get a downstream air pressure within a .5 PSI accuracy of the pressure reading on the gauge.

General purpose air pressure regulators ordinarily have an operating range in the area of of 0 – 120 PSI. Others are going to be rated for pressures of 0-100 or 0-150 PSI.

You can also get air regulators with a narrower and more specialty oriented range of pressures such as: 0-10 PSI, 0-20, 20-60 PSI then on. At the other end of the size , you’ll purchase regulators which will safely handle many thousands of PSI.

For most do-it-yourself types, a general compressed air regulator with a variety of 0-100 PSI will do exactly fine.
