Midland Industries AR6 Air Line Regulator 150 Psi 1/4 in

Product Description

The MIDLAND INDUSTRIES AR6 is an air line regulator designed to control and maintain downstream pressure in pneumatic systems. The zinc body houses a rotary flow regulator and accepts a 1/4 in FNPT swivel inlet with a 1/4 in MNPT outlet, making it straightforward to integrate into compressed air lines. Operating pressure is rated to 150 psi, with an adjustment range of 5 to 140 psi. Body construction combines zinc, copper, steel, and polymer components. Licensed HVAC technicians, plumbers, and industrial maintenance techs commonly install this type of regulator when consistent downstream air pressure is required for tools, instrumentation, or pneumatic controls.

The AR6 is suited for light industrial and commercial pneumatic applications where regulated compressed air is needed at a point of use. The swivel inlet simplifies alignment during installation in tight or fixed-pipe configurations. Its compact form factor and standard 1/4 in NPT connections make it a common fit for air tool supply lines, pneumatic control circuits, and auxiliary compressed air drops in mechanical rooms or shop environments.

Key Features

• 150 psi maximum operating pressure with 5 to 140 psi adjustment range
• Rotary flow regulator for precise downstream pressure control
• 1/4 in FNPT swivel inlet allows angular adjustment during installation
• 1/4 in MNPT outlet provides standard threaded connection to downstream components
• Multi-material construction: zinc body with copper, steel, and polymer internals
• Compact footprint at 2.2 inches body length

Compatibility

Designed as an OEM-style replacement or direct installation regulator for pneumatic systems using standard 1/4 in NPT compressed air lines rated up to 150 psi.

Installation Notes

Installation is typically performed by a licensed HVAC technician, pipefitter, or qualified maintenance mechanic. Always depressurize and lock out the compressed air supply before installing or removing any regulator. Apply thread sealant appropriate for compressed air service to all MNPT connections. Verify adjustment range meets downstream equipment requirements before returning the system to service.
