Filter & Regulator AW1000～5000 Series

Filter and Pressure Reducing Valve Control and filter compressed air

The filter and pressure reducing valve combines a compressed air filter and a pressure reducing valve in one device, thus performing two functions simultaneously. The filter can remove impurities from the compressed air, while the pressure reducing valve controls the required working pressure according to the application. It can ensure high process safety, reduce machine failures, and shorten downtime, so it has become an indispensable component in the air source treatment device.

Product Series

The AW Series air filter-regulator, commonly referred to as a two-in-one unit, is an essential air preparation component installed at the front end of pneumatic automation systems. This innovative design integrates an air filter and a pressure regulator into a single compact unit, delivering two critical functions in one device: compressed air purification/filtration and stable pressure regulation. It replaces the traditional separate assembly of a filter and regulator, and is widely used in conjunction with pneumatic actuators, cylinders, pneumatic valves, and automated tooling equipment. It continuously supplies clean, pressure-stable compressed air to downstream pneumatic components, making it a fundamental core component in fluid automation piping and pneumatic control systems.This series of filter-regulators is extensively deployed across all automated equipment incorporating pneumatic elements, and is particularly well-suited for complete pneumatic valve systems, including: Fluid pipelines: upstream air preparation for pneumatic butterfly valves, pneumatic ball valves, and scotch-yoke actuators Automated production lines, assembly equipment, and pneumatic tooling fixtures Packaging machinery, environmental protection & water treatment equipment, and electroplating/corrosion-resistant complete systems Woodworking machinery, printing equipment, and rubber & plastic machinery Installation Recommendations: Install upstream of solenoid valves and pneumatic actuators. Mount vertically, with the filter bowl facing downward. For applications involving organic solvents or high-temperature splashing environments, a metal protective bowl is recommended.

Product Features

1. Integrated Design – Space-Saving Installation Combines filtration and pressure regulation in a single compact unit, minimizing pipe connections, reducing potential leak points, and simplifying air circuit layout. Ideal for space-constrained installations within equipment enclosures. 2. Dual Purification – Protects Downstream Pneumatic Components Supplied with standard 5μm filter element (40μm optional), effectively removing moisture and solid particulates with high efficiency. Prevents internal wear of cylinders and pneumatic actuators, seal degradation, and valve sticking – significantly extending the service life of pneumatic components and reducing equipment downtime. 3. Relieving Type Pressure Regulator – Precise & Stable Control Features built-in relieving function that automatically vents excess pressure when line pressure rises, ensuring stable outlet pressure. The adjusting knob incorporates a self-locking mechanism to prevent pressure drift caused by vibration. Smooth linear pressure adjustment accommodates both general-purpose and precision pneumatic applications. 4. Extensive Selection – Flexible Configuration Available in various housing sizes with port connections from M5 to G1. Offers both manual drain and automatic float drain options. Choose between transparent PC bowl (for visual level monitoring) or metal protective bowl (impact-resistant and solvent-resistant). Optional accessories include pressure gauge, mounting bracket, and reverse-flow modules.

5. Modular Standard Interface – Universal Compatibility Designed in accordance with industry-standard modular air preparation specifications. Components within the same series can be freely combined and interchanged, ensuring compatibility with most major brands of pneumatic actuators and solenoid valves – facilitating standardized integration in complete equipment packages.

6. Easy Maintenance – Quick Service The filter bowl can be rapidly detached, and the filter element is simple to replace. The transparent bowl allows direct visual inspection of accumulated condensate and element contamination, enabling timely scheduled maintenance.

How To Use And Maintain

1. Before use,check the unit to see if it is damaged during the course of transport,and if the joint part is loose.Then install for use. 2. When installing,pay attention to the direction of airfl ow and keep the unit upright. 3. When the inlet and outlet belts are in reduced connection,the fl ow rate of the units is reduced by 10% approx,With each upgraded class of fi l tering precision, the rate of fl ow will be reduced by 7% approx. 4. For units with a protective cover,make sure cover is fi xed before use to avoid danger. 5. When use the regulator or fi lter & regulator,it is required to adjust the contral hand wheel to the zero position fi rst.Fix the pressure gage and end plug on the corresponding positions of the regulator or fi lter & regulator and ensure they are air-tight(positions of the pressure gage and end plug may be exchanged)Then let in air and adjust to a proper pressure. 6. When using the lubricator,it is required to adjust the oil quantity valve needle to the zero position and add appropriate oil to the level line fi rst. Then adjust to a proper position after letting in required air.Pay attention to the brand and grade of the lubricating oil.Never use spindle oil and lubricating oil containing lower ketone or aromatic hydrocarbon. 7. When using metal tubes for for connection,remember to remove the metal grains,dusts and oil stains in the tubes.
