SMC 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. Use joiner clamps (sold separately) to connect them to other SMC units of the same series, so you can customize your air preparation system. These regulators come with one regulated outlet on their back and one unregulated outlet. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after filters.
Joiner clamps (sold separately) create compact, airtight connections between components. These clamps 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.
End caps (sold separately) seal off any unused pipe ports on SMC modular systems. They attach with a joiner clamp (not included).
Mounting brackets (sold separately) allow you to attach these regulators to a wall or equipment.

Compressed Air Regulating Manifolds

Use a single air supply to meet the pressure requirements of multiple applications—connect one of these manifolds to your air line, and then set a different output pressure for each station. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install in your air line after filters.
Style A manifolds are good for small air-powered tools and pilot plants where low flow and precise control are important.
