Tamper-Resistant Compressed Air Regulators
Prevent unauthorized adjustment and unintentional pressure changes with these regulators. Use them in your air line to adjust and maintain the pressure of your compressed air. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install in your air line after filters.
Regulators with a key lock provide an extra level of security. Set your pressure, lock it, and remove the key to prevent further adjustment. They have a universal lock so you can use the same key for multiple regulators.

Festo 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. They have a locking head to prevent unintentional pressure changes. Install in your air line after filters.
Joiner clamps (sold separately) connect the regulator to another Festo 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.

Compressed Air Regulators for Air-Powered Tools
Designed for installation directly to your air-powered tool, these regulators maintain the set air pressure.
Relieving regulators exhaust when the downstream pressure exceeds the set pressure. Regulators with a collar adjustment have a screw lock to prevent unintentional changes or tampering with the set pressure. Turn the collar to adjust the pressure.

Festo Modular Compressed Air Filter/Regulators for Particle Removal
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 and have a locking head to prevent unintentional pressure changes. Filter has a clear bowl or sight glass so you can see inside to monitor contents. Regulator is nonrelieving style, so it does not exhaust excess downstream pressure.
Joiner clamps (sold separately) connect the filter/regulator to another Festo modular component with the same series number. They come with mounting brackets to attach the filter/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.

Parker Modular Compressed Air Filter/Regulator/Lubricators (FRLs)
A Parker filter, regulator, and lubricator are combined to provide clean, lubricated compressed air at your required pressure. They come with a safety lockout valve for one convenient unit that's ready to use. The valve can be locked in the shut-off position to prevent accidental start-up when servicing equipment. Regulator is relieving style, so it exhausts when the downstream pressure exceeds the set pressure. Filter and lubricator have a clear bowl so you can monitor the contents inside.
Stacked filter/regulator/lubricators require less horizontal space than inline FRLs. The filter and regulator are joined top-to-bottom with the lubricator on the side.
Mounting brackets allow you to attach the filter/regulator/lubricator to a wall or equipment.

Compressed Air Filter/Regulator/Lubricators (FRLs)
for Lubricated and Nonlubricated Applications
With one outlet port before the lubricator and one after, these filter/regulator/lubricators work in systems that require lubrication in some lines but not in others. A stacked configuration requires less horizontal space than inline FRLs. The filter and regulator are joined top-to-bottom with the lubricator on the side. They come with a safety lockout valve for one convenient unit that's ready to use. The valve can be locked in the shut-off position to prevent accidental start-up when servicing equipment. Regulator is relieving style, so it exhausts when the downstream pressure exceeds the set pressure. Filter and lubricator have a clear bowl so you can monitor the contents inside.
