    Clean Room Precision Compressed Air Regulators

    When precision and cleanliness are critical—such as semiconductor manufacturing and food processing—these regulators are cleaned and bagged in an ISO Class 3 clean room to prevent contamination. They deliver steady air pressure to generate precise, repeatable movement. A locking adjustment knob secures your settings to prevent accidental changes. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after filters.

    Clean Room Panel-Mount Pressure-Regulating Valves for Air and Inert Gas

    Maintain contaminant-free standards in clean room environments. These valves come cleaned and bagged to Fed. Spec. Class 100 and ISO Class 5 clean room standards and have a 316 stainless steel body with a smooth finish to resist dust collection. They automatically reduce a high, variable inlet pressure to a lower, stable output pressure. Valves have threads below the adjustment knob and come with a panel-mount nut. Adjust the outlet pressure within the range.

    Clean Room Compressed Air Filter/Regulators for Particle Removal

    Image of Product. Front orientation. Compressed Air Filter/Regulators. Clean Room Compressed Air Filter/Regulators for Particle Removal.
    Assembled, inspected, and packaged in a clean environment, these filter/regulators come sealed in antistatic double bags. The filter and regulator are joined top-to-bottom to fit in the same space as a filter alone. They provide clean compressed air at your required pressure. The filter has a clear bowl, so you can see inside to monitor contents from every direction. The regulator is relieving style, so it exhausts when the downstream pressure exceeds the set pressure. Run a tube from the open drain port to a disposal point, such as a drain pan or waste system.
