Optimize your pneumatic systems with our versatile filter-regulator combination units. These compact devices deliver clean, precisely regulated compressed air, protecting your valuable equipment, enhancing operational consistency, and simplifying your air preparation setup.
Combines essential air filtration and pressure regulation into a single unit, significantly saving installation space and reducing piping.
Delivers clean, particulate-free air at a stable, precisely controlled pressure for optimal performance of downstream equipment.
Fewer components to install and maintain means reduced setup time and lower long-term operational costs.
A filter-regulator (FR) unit efficiently combines an air filter and a pressure regulator into a single, compact housing. Compressed air first enters the filter section, where solid particles and condensed moisture are removed. The cleaned air then passes to the regulator section, where its pressure is precisely controlled and stabilized to the desired setpoint before being delivered to downstream pneumatic devices.
Advanced filter elements provide excellent removal of water, oil, and particulate matter, ensuring high-quality compressed air.
High-sensitivity diaphragms and precise adjustment mechanisms ensure stable output pressure with minimal fluctuation.
Constructed with quality materials to withstand industrial environments, offering long service life and reliability.
Clear bowls for visual inspection of condensate, easy-to-use drains, and simple filter element replacement.
E.g., G1/8, G1/4, G3/8, G1/2, G3/4, G1, NPT options.
Standard levels (e.g., 5µm, 25µm, 40µm); finer options available.
The adjustable output pressure range (e.g., 0.05-0.85 MPa).
Maximum allowable inlet pressure.
Rated airflow at a specified pressure (e.g., L/min, SCFM).
Polycarbonate (standard) or metal (for higher pressures/temperatures).
Manual, semi-automatic, or fully automatic drain.
Availability of integrated or port for external pressure gauge.

A compact and essential unit for home workshops using smaller compressors and air tools.
Always de-pressurize the system before performing any maintenance on filter-regulator units.
A filter-regulator (FR) unit combines two essential air preparation functions into a single, compact device:
Essentially, it provides clean, pressure-controlled air to pneumatic components.
Most filter-regulators have an adjustment knob on top. To set the pressure:
Always set the pressure to the minimum required for the application to save energy and reduce wear on components.
Standard filter-regulators typically provide particulate filtration. The most common filtration ratings for general-purpose FR units are:
These units also remove bulk liquid water through cyclonic separation and baffles. However, they do not typically remove oil aerosols or very fine sub-micron particles. For oil removal or higher purity air, separate coalescing filters or activated carbon filters would be needed in addition to or in place of the standard filter section.
Yes, a filter-regulator (FR unit) only provides filtration and pressure regulation. It does not add lubrication to the air stream.
If your downstream pneumatic components (like certain air tools or older cylinder designs) require oil mist lubrication for proper operation and longevity, you would need to add a separate lubricator unit downstream of the filter-regulator, or use a combined Filter-Regulator-Lubricator (FRL) unit.
Using an FR unit alone in a system that requires lubrication will result in those components running dry, leading to increased wear and premature failure.
This refers to how the regulator handles excess downstream pressure:
Most general-purpose filter-regulators will feature a relieving-type regulator.
