On a Rush? Here Our Best 5 Regulators
The air regulator on an air compressor is a small yet important air compressor component. Its primary function is to maintain consistent air pressure. To get the best output, you must choose your regulator wisely.
Finding the perfect one can be difficult because there is so much research to be done. However, we have done the research for you and compiled a list of the best air compressor regulator options on the market. We have also devised a handy guide to help you know how to make the right choice. Before getting to these, however, it is essential first to understand how a regulator works and what it does.
What Does a Regulator Do on an Air Compressor?
Most air tools and other equipment have a supply pressure that is invariably lower than the compressor’s operating pressure. Because a device operating at seven-bar consumes twice as much compressed air as one operating at three-bar, using a supply pressure regulator to lower the supply pressure saves both money and energy.
The input pressure level of a compressed air system can change based on the system’s configuration. However, when you use a pressure regulator, it will maintain a consistent outlet pressure. You can view the outlet pressure using the pressure gauge on the air compressor.
How Does a Regulator Work?
The airflow across the tank is controlled by a set screw. A screw shaft is attached to a spring, which determines the pressure of the air. This spring is then attached to a diaphragm that moves when there is a change in pressure. To maintain constant pressure, the regulator merely manages the diaphragm’s movement.
Choosing the Right Air Pressure Regulator
Finding the right regulator for your air compressor can be challenging, especially if you don’t know what to look for. This is why we have put together a guide to help you make the right choice.
Operating Pressure Level
You can adjust the maximum pressure output to a certain level using the operating pressure level of your air regulator. Therefore, it is essential that it be compatible with your air compressor.
The regulator can be damaged if the air compressor produces a high pressure that the air pressure regulator cannot bear. You should always choose a higher operating pressure level regulator than the air compressor to prevent this from happening.
Decide Which Type of Regulator is Best for Your Compressor
Some air regulators only regulate air pressure, whereas others filter air using a built-in air filter. These filters work to remove solid particles from the compressed air, and the results are clean, dry air for powering your air tools.
Go for a regulator without an air filter if you have no use for it. However, if you prefer a regulator with an air filter, several options are available.
NPT Size
The NPT size is the size of the regulator’s input and outlet. The compressor will attach to both the input and the outlet. While some regulators have universal sizes that will fit onto any compressor, others must be bought according to the compressor it is to be used for.
To ensure that you purchase the proper regulator for your air compressor, you must compare the NPT size of the regulator with your air compressor.
Additional Accessories
The truth is that despite its build quality, your air regulator will inevitably experience air leakage. Threaded sealants can help you prevent this from happening.
You can buy this thread sealant as an optional extra. However, several manufacturers sell these sealants with the regulator, which can help you save money. When buying your regulator, you can also look for other additional accessories, such as an air filter or pressure gauge.
Some regulators also have drainage options. You can choose from a semi-automatic or manual drain and a polycarbonate bowl or a metal bowl. Other accessories include a metal bracket, metal guard, and Teflon tape.
The Best Air Compressor Pressure Regulator: Our Top 5 Picks
Finding the correct parts for your air compressor can be confusing as many different products are on the market. Fortunately, you don’t have to spend hours reading reviews and specifications, as we have done the research for you. Here are our top five air regulator picks.

2. Nanpu Compressed Air Filter Regulator
This is a great option for those who need a regulator with an air filter. It has an operating pressure of 0 to 145 PSI and is available in eight different NPT sizes, with a five-micron brass filter element that offers outstanding filtration and an extended lifespan.
You also get several accessories with this air supply filter regulator, including a polycarbonate bowl, semi-auto drain, an air coupler plug kit, 0 to 150 gauge and wall-mounting bracket, and thread seal tape. The flow rate of this air compressor regulator is 18 SCFM at 90 PSI.
3. Craftsman D27253 Air Compressor Regulator
The Craftsman D27253 Air Compressor Regulator is a good choice for reliability and consistency. It is one of the most accurate and precise air compressor filter regulators on the market. The product has been designed to handle any outlet pressure. It can be used for a wide range of applications, including regulating compressed air for air tools and other pneumatic equipment.
This air compressor pressure regulator can be used with any kind of air compressor, regardless of its size, which is excellent if you have more than one air compressor that is not used simultaneously.
4. PneumaticPlus SAU320-N03G Compressed Air Filter Regulator Combo
The PneumaticPlus SAU320-N03GFilter Regulator provides pressure control and additional filtration. This is why it is one of the greatest regulator filters on the market. This device not only regulates pressure but also acts as a filter, removing hazardous particles as small as 10 microns. You can choose from a variety of drain and bowl configurations to suit your needs, which is another great feature.
The SAU320-N03G is suitable for a 3/8-inch NPT size. However, the company offers a variety of filter regulators with varying specifications. This product also has a supply pressure of 250 PSI and includes accessories such as a pressure gauge and a bracket.

Final Thoughts
Air regulators are important tools that can help maintain constant pressure in your air compressor. It is essential to check the NPT size and pressure output levels before choosing a pressure regulator and determine whether you would like a regulator that just maintains consistent pressure outputs or whether you would also like additional functions, such as air filtration.

Frequently Asked Questions (FAQs)
The section below answers some of the most pressing filter regulator questions.
Do I Need a Filter Regulator on My Air Compressor?
Many air compressors do need a regulator, whereas others do not. Those that need a filter regulator, or an air pressure regulator typically have one built-in. However, this built-in regulator may wear out with time. In this case, you’ll have to buy an additional regulator for your air compressor to maintain constant air pressure.
What Oil Do You Use in an Air Compressor Pressure Regulator?
SAE detergent commercial petroleum-based motor oil is recommended for use in regulators. If 10wt. or 20wt. oil is unavailable, 10w30 SAE detergent petroleum-based motor oil may be substituted. Synthetic oils should be avoided since they degrade and cause a black grease buildup in the device.
How Do You Adjust an Air Compressor Pressure Regulator?
A pressure regulator is relatively easy to adjust. Simply turn the dial after attaching the filter regulator to the compressor to raise the pressure. Reduce the pressure by turning the dial to the left. You can adjust the pressure to your chosen level by lowering or raising it.
