Pro-source NR200-01N Air Regulator 1/8 Npt 170 Psi

Product Description

The PRO-SOURCE NR200-01N is a miniature compressed air regulator designed to control and maintain downstream air pressure in pneumatic systems. Built from aluminum, it accepts a 1/8 inch NPT port connection and handles inlet supply pressures up to 170 psi. The regulated output range spans 2 to 120 psi, making it suitable for precision pressure control in tight spaces where a full-size regulator will not fit. A built-in relief function vents excess downstream pressure when the set point is reduced. Flow capacity reaches 53 CFM. HVAC technicians, pneumatic system integrators, and maintenance professionals install this regulator inline on compressed air lines feeding tools, actuators, or control components.

The NR200-01N fits applications requiring compact, reliable pressure regulation in both light industrial and commercial settings. Its miniature form factor suits panel-mount assemblies, manifold stations, and inline installations on small-bore pneumatic lines. The 1/8 inch NPT threading is standard across a wide range of pneumatic fittings and valves, simplifying integration into existing compressed air circuits. No pressure gauge is included, though the gauge port thread size is 1/8 inch NPT if a gauge needs to be added. The unit is rated for use with compressed air only and operates at temperatures as low as 14 degrees F.

Key Features

• Miniature form factor fits tight panel and inline installations
• Pressure regulation range of 2 to 120 psi with a 170 psi maximum supply pressure
• Built-in relief function releases excess downstream pressure automatically
• 53 CFM air flow capacity supports most light-duty pneumatic tool and actuator circuits
• Aluminum body construction for lightweight, corrosion-resistant service
• 1/8 inch NPT gauge port allows optional gauge addition without additional adapters

Compatibility

Designed as an OEM-style replacement or new-install miniature compressed air regulator for pneumatic systems using 1/8 inch NPT connections and requiring a maximum supply pressure rating of 170 psi.

Installation Notes

Installation should be performed by a qualified pneumatic or mechanical technician. Depressurize the air line fully and lock out the compressor before installing or removing the regulator. Use thread sealant appropriate for compressed air service on all NPT connections and do not overtighten fittings into the aluminum body. Verify downstream pressure with a calibrated gauge after installation to confirm the regulator is set to the required output pressure before returning the system to service.
