Midland Industries AR7 Air Line Regulator 160 Psi 1/4 in

Product Description

The MIDLAND INDUSTRIES AR7 is an inline air line regulator designed to control downstream air pressure in pneumatic systems. Built with an aluminum body incorporating a dynamic rotary flow restrictor, this regulator accepts supply pressure up to 160 psi and allows the technician to dial in output pressure across an adjustment range of 5 to 145 psi. The 1/4-inch FNPT inlet and 1/4-inch MNPT outlet make installation straightforward in standard compressed-air plumbing. At 0.125 pounds, the AR7 is compact enough for tight panel or inline installations where weight and space are limited.

The AR7 is suited for residential and light commercial pneumatic applications where regulated downstream pressure is required. Typical use cases include air tool supply lines, pneumatic control circuits, and compressed-air distribution systems that require stable output pressure regardless of fluctuating supply. The unit is sized for inline installation in 1/4-inch air lines and is appropriate for both shop and field service work where portable or fixed compressed-air systems are in use.

Key Features

• Maximum inlet pressure of 160 psi suits most shop and field compressed-air supplies
• Adjustment range of 5 to 145 psi provides broad downstream pressure control
• Dynamic rotary flow restrictor integrated into aluminum body for consistent regulation
• 1/4-inch FNPT inlet x 1/4-inch MNPT outlet for direct inline installation
• Lightweight aluminum construction at 0.125 pounds minimizes added load on air line assemblies

Compatibility

Designed as an OEM-style inline replacement or new-installation regulator for 1/4-inch NPT pneumatic air lines in residential and commercial compressed-air systems.

Installation Notes

Installation is typically performed by a qualified pipefitter, HVAC technician, or pneumatic systems technician. Depressurize and isolate the air supply line completely before removing or installing any inline regulator. Use thread sealant rated for compressed-air service on all NPT connections and verify all fittings are leak-free before returning the system to pressure. Follow applicable local codes and OSHA compressed-air safety guidelines during service.
