Corrosion-Resistant Compressed Air Regulators

With Knob

Made with a corrosion-resistant housing, these regulators withstand harsh environments where standard regulators would break down and fail. Use them to adjust and maintain the pressure of compressed air. These regulators are relieving, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after filters.

316 stainless steel regulators stand up to harsh chemicals and chlorides, so they're often used in facilities that manufacture semiconductors, chemicals, and paper. Their housing and bowl meet NACE (National Association of Corrosion Engineers) standards for performance in corrosive environments.

Mounting nuts (sold separately) let you attach the filter/regulator to a control panel.

Corrosion-Resistant Compressed Air Filter/Regulators for Particle Removal

Opaque with
Manual
Drain

Built to resist corrosion, these filter/regulators withstand harsh environments that would cause standard filter/regulators to break down and fail. The filter and regulator are joined top-to-bottom, so they fit in the same space as a filter alone. They provide clean compressed air at your required pressure. The regulator is relieving, so it will exhaust when the downstream pressure exceeds the set pressure.

316 stainless steel filter/regulators stand up to harsh chemicals and chlorides, so they're often used in facilities that manufacture semiconductors, chemicals, and paper. Their housing and bowl meet NACE (National Association of Corrosion Engineers) standards for performance in corrosive environments. Add mounting nuts (sold separately) to attach them to a control panel.
