Wilkerson Modular Compressed Air Regulators

Adjust and maintain the pressure of your compressed air. All regulators are relieving style, so they exhaust when the downstream pressure exceeds the set pressure. Install in your air line after filters.
Mounting brackets (sold separately) allow you to attach the regulator to a wall or equipment.
Joiner clamps (sold separately) connect the regulator to another Wilkerson modular component with the same series number. They come with mounting brackets to attach the regulator to a wall or equipment.
End block sets (sold separately) allow you to swap out filter/regulator/lubricator components without unthreading your air line connections. The blocks remain connected to your pipe while you replace components between them.
Fit a nonrelieving diaphragm assembly (sold separately) to the regulator to stop it from exhausting excess downstream pressure. This is helpful if you are using a gas you do not want released into the air automatically, such as an expensive noble gas.
