About Air Preparation

Wilkerson Modular Compressed Air Regulators

Set and maintain the pressure of your compressed air. These regulators connect to other Wilkerson units of the same series with joiner clamps (sold separately)—even if the pipe sizes are slightly different—so you can customize your air preparation system. They’re relieving, so they will exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after filters.
BSPP threads are also known as G threads.
Mounting brackets (sold separately) allow you to attach the regulator to a wall or equipment.
Joiner clamps (sold separately) create compact, airtight connections between components. All include a wall-mounting bracket, except for clamps in the R90 series.
End block sets (sold separately) allow you to swap out 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 these regulators to stop them from exhausting excess downstream pressure. They’re helpful if you’re using a gas you don’t want automatically released into the air, such as an expensive noble gas.

Wilkerson Modular Compressed Air Regulator Manifolds

Connect two or more of these manifold regulators to meet multiple pressure requirements from a single air supply—set a different output pressure with each regulator. Each regulator has two regulated outlets, one unregulated outlet, and an additional port that can be used for a pressure gauge. Regulators are relieving style, so they exhaust when the downstream pressure exceeds the set pressure. Install in your air line after filters.
Joiner clamps (sold separately) connect manifold regulators to each other and other Wilkerson modular components 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.
Gauges are not included with Series No. 19 manifold regulators.

Wilkerson Modular Compressed Air Filter/Regulators for Particle Removal
and Nylon
Guard

A filter and regulator joined top-to-bottom, these filter/regulators fit in the same space as a filter alone. They provide clean compressed air at your required pressure. Filter has a clear bowl or sight glass so you can see inside to monitor contents. Regulator is relieving style, so it exhausts when the downstream pressure exceeds the set pressure.
Mounting brackets (sold separately) allow you to attach the filter/regulator to a wall or equipment.
Joiner clamps (sold separately) connect the filter/regulator to another Wilkerson modular component with the same series number. They come with mounting brackets.
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 filter/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.
