Air Gas Filters
No matter what the industry, contamination of gas stream such as compressed air and natural gas can dramatically increase maintenance costs and even shut your process or plant down. That’s why leading companies all over the world rely on R.P. Adams steam filters to prevent clogging and friction wear caused by slime, rust, pipe scale, solid as well as airborne particles including dirt, oils, carbon, and moisture. R.P. Adams high-performance GP Filters, you simply can’t find more effective or reliable filtration to protect sensitive process equipment such as control valves and pneumatic tools. Just what you’d expect from the pioneer of advanced filtration technology.

Two-Step Separation Guarantees Maximum Filtration
Gas is directed in a tangential flow around the element and against the inside wall, providing centrifugal separation of larger particles and droplets. Contaminants are captured in patented vertical slots located on the filter’s side walls. A gas flow interrupter at the bottom of the unit improves draining efficiency and reduces condensate pick-up from liquid collected before the drain. The gas is then diffused through the Poro-Stone tube to achieve maximum filtration.
The Poro-Stone element and corrosion-resistant cast ductile iron filter body on sizes 1/2” to 3” withstand temperatures up to 650ºF. For sizes 4” and larger, a combination of fabricated carbon steel and cast iron is furnished. Units also are available in stainless steel construction.
Meeting Industry Standards
GP are designed for, and can be certified to meet the requirements of Section VIII, Division 1, of the ASME code.
Design Pressures to 500 PSIG
GP Filters are capable of handling pressures up to 500 PSIG. Standard units with design pressures of 150 PSIG and 3200 PSIG are available from stock.
Inline Process Connections Easy Installation
Inlet and outlet connections are in line with process piping to simplify installation.
Five Micron Filtration
The Poro-Stone element is capable of nominal five micron filtration, making it suitable for removal of cellular structures such as bacteria and slime.
Durable Tube Construction
Filter element is an aluminum oxide with silica bond inert ceramic structure which provides superior durability to handle the toughest applications. There are no moving parts. The Poro-Stone tube is directly attached to the filter cover which makes it easy to remove and replace the element.
Cleanable Filter Element
The Poro-Stone element can be cleaned and reused for years of effective filtration.
Unlike other filter cartridges, the Poro-Stone element will never collapse, even when plugged, to fully protect your process and processing equipment.
Protects Sensitive Instrumentation and Pneumatic Equipment
Prevents clogging and friction wear caused by dirt, pipe scale and entrained water or oil. Filters can be used at the point of use, or in the main process stream.
When near fog conditions are a problem, two GP filters in series can provide superior demisting and filtration
The GP filter can serve as an excellent flame arrester to protect expensive equipment.
