A filter and regulator joined top-to-bottom, these filter/regulators trap particles and maintain pressure in your compressed air line. They connect to other SMC units of the same series with joiner clamps (sold separately), so you can customize your air preparation system. The regulator is relieving, so it will exhaust when the downstream pressure exceeds the set pressure.

Aluminum bowls are stronger than plastic bowls. They won’t crack or shatter if dropped.

BSPP threads are also known as G threads.

Joiner clamps create compact, airtight connections between components, even if the pipe sizes are slightly different. They come with mounting brackets.

Compressed Air Filter/Regulators for Double-Acting Cylinders

Push filtered, stable compressed air downstream to your system—even when your double-acting cylinder sends a rush of reverse airflow. These filter/regulators have a check valve that blocks backflow to protect the internal components of the regulator. The regulator is relieving, so it will exhaust when the downstream pressure exceeds the set pressure.

Stacked vertically, these filter/regulators take up no more space than a filter. Use the mounting bracket to attach them to a wall or equipment.
