RS PRO B49G Pneumatic Regulator, 5μm, Automatic

Introducing the range of RS PRO Filter Regulators, designed as a robust and high-quality pneumatic regulator with a combined air filter that’s ideal for maintaining constant output pressure and clear air flow in a wide range of pneumatic applications. By using a filter and regulator combination, it ensures that the flow of liquids and compresses air can be precision controlled, while at the same time removing dirt and impurities which provides clean, safe and reliable air flow. The robust housing ensures optimum performance and is easy to connect and install, saving on valuable time and resource.

Pneumatic filter regulators, sometimes also referred to as pressure regulators, are devices used to regulate air and maintain a stable source of pressure for a wide range of process control equipment. High pressure enters the regulator through an inlet and into the valve chamber where an adjustable knob operates a spring to generate a force, causing the valve to open. This applies pressure to a piston that causes the valve to close until the required amount of pressure is maintained and regulated. The combination of a filter ensures that any air or liquid that is regulated is filtered and clean, helping to prolong the life of pneumatic devices. Filter regulators are used in a wide range of devices and pneumatic equipment and are commonly found in areas such as:

• Industrial automation


• Medical and dental


• HVAC
