Air regulators control the supply, pressure or chemical composition of air in pneumatic controllers, transmitters, transducers, valve positioners, air cylinders and other pneumatic control systems.

Air regulators are a vital part of many operating units, such as power plants, chemical laboratories, hospitals and other units where air plays an important role in day-to-day activities.

Some important parameters you must consider before purchasing an air regulator are:

1. Inlet air pressure
2. Flow rate and capacity required
3. Operating temperature range
4. Type of regulator depending on the application: an air pressure regulator, an airflow regulator or an air filter regulator

Action Steps
The best contacts and resources to help you get it done

Buy air regulators from manufacturers

Once you have identified your requirements, buy an air regulator that is most suitable for your application. For example, an air filter regulator is the best option for applications that require clean and pure air.

I recommend: You can buy a miniature precision air regulator from ControlAir, a reputable manufacturer that offers a variety of brass and steel air regulators. You can also choose from different air regulators on sale at Parker Hannifin, another supplier of air pressure regulators. Air Logic provides subminiature air regulators and modular air regulators suitable for medical and other industrial applications. For electronic air regulators, browse the products offered by SMC. Furthermore, Graco manufactures low-pressure air regulators for spray guns used in metal finishing industries.

Buy an air regulator from air regulator distributors

You can compare different industrial air regulators along with their prices at distributors' websites.

I recommend: Air Inc. offers various industrial air regulators, including precision and instrument regulators. Industrial Specialties Mfg. distributes air pressure regulators such as nickel-plated brass regulators and miniature precision regulators. For an air compressor regulator, go to Every Air Compressor, a distributor of air compressors and accessories. Ellis Kuhnke Controls provides air pressure regulators, airflow regulators and other pneumatic products.

Buy a custom air regulator

If the standard products available in the market do not meet your specific requirements, opt for a customized air regulator.

I recommend: Generant is a custom manufacturer of air pressure regulators for cryogenic applications. Bosch Rexroth is a reputable automation controls and equipment provider that offers customized self-relieving air pressure regulators. Tescom is another custom manufacturer that supplies explosion-proof electronic air regulators. You can buy a customized miniature precision air regulator at Marsh Bellofram, a manufacturer of all types of air regulators. Sizto Tech supplies customized aluminum air pressure regulators. Pneumadyne designs and manufactures pneumatic regulators and valves as per your requirements.
