SMC AW20 Air Filter & Pressure Regulator

Overview

The SMC AW20 Air Regulator is a high-quality industrial filter/regulator combination unit designed to prepare compressed air for pneumatic systems. This modular pneumatic component integrates two essential functions — filtration and pressure regulation — into a single compact housing, reducing installation space and piping complexity. 

SMC’s AW20 series conforms to international standards and is widely adopted in automation systems, machine tools, packaging machinery, and other industrial applications where clean, consistent air pressure is critical for reliable performance and longevity of pneumatic actuators and valves. 

Key Functions and Advantages

• Air Filtration: Removes particulate contaminants and condensed moisture from compressed air with fine filtration (typically ~5 µm), protecting downstream pneumatic components from wear and malfunction. 

• Pressure Regulation: Precisely controls output pressure within a specified range (often 0.05-0.85 MPa depending on configuration), ensuring stable air delivery for sensitive pneumatic systems. 

• Space-Saving Design: By combining a filter and regulator in one unit, the AW20 series minimizes panel footprint and simplifies installation. 

• Easy Maintenance: Transparent bowl guard (on many variants) allows visual inspection of trapped contaminants and easy manual drainage or replacement. 

• Flexible Port Sizes: Offered with multiple connection thread options (e.g., G 1/8, G 1/4, NPT) to match diverse pneumatic line layouts. 

Industrial Applications

The SMC AW20 Air Regulator is widely used in areas requiring controlled pneumatic power, including:

• Factory automation and control systems

• Pneumatic actuators and tooling

• Packaging equipment and assembly lines

• Material handling systems

• Air supply panels and compressed air distribution units

  In these environments, using a reliable filter/regulator like the AW20 helps maintain consistent system performance while reducing maintenance costs and downtime. 

Installation & Integration

Installation is straightforward — the AW20 can be mounted individually or as a part of larger FRL (Filter-Regulator-Lubricator) assemblies. Many variants support panel mounting or bracket attachments, and optional gauges or condensate drains may be fitted for enhanced monitoring and maintenance convenience.
