All pneumatic motion requires clean and dry air with enough flow to provide the required pressure. The process of filtering, regulating and lubricating compressed air is known as air prep. Facilities need air prep at centralized compressors; additional air prep is advantageous at the machine level also.
For industrial pneumatics systems, air preparation (often called "air prep") is a fundamental and often underappreciated necessity. Clean air at the proper pressure is needed for reliable system operation, and for reducing maintenance costs and downtime.
Pneumatic air filters, regulators, lubricators, soft start/dump valves and air relief valves are available in a wide variety of port sizes to meet a broad range of pneumatic air supply filtration, air regulation and compressed air lubrication applications. The modular design of these products allows stand-alone applications and also enables easy field assembly for combining compatible air prep components.
Combination air-prep units offer multiple functions in a single easy-to-install device, typically including a filter regulator, shutoff, pressure gauge and lubricator.

Particulate and moisture separation air filters are used for cleaning incoming compressed air sources. Coalescing filters can remove water and oil mist.
Particulate filters and coalescing type filters available offer:

Pneumatic air supply lubrication can increase speed, slow wear and reduce leakage in and around operating components.
Lubricators start at
Control valves are manually or solenoid operated valves used to shut off upstream pressure and relieve downstream pressure. Soft-start valves gradually increase air pressure downstream when energized, and quickly dump downstream pressure when de-energized.
Valves start at
Lockout valves are critical components in any safety lockout/tagout system, ensuring that downstream systems can be depressurized for maintenance or other purposes.

Precision combination filter and regulators are ideal for systems that require clean, accurate instrument air in industrial environments.
Mounting components for air prep units make installation easy and clean. Quickclamp and mounting brackets are available for Norgren units, and L-, T- and U-brackets for NITRA units allow for installation just about anywhere, even in locations with limited space.
