ZHONG AN 1/4″ NPT Air Pressure Regulator with Gauge

The ZHONG AN 1/4″ NPT Air Pressure Regulator with Gauge (Model AR-2000) is designed to precisely regulate and maintain constant air pressure within pneumatic systems. Operating within a pressure range of 0–145 psi, this control valve enables users to adjust and monitor working pressures effectively, ensuring connected equipment receives the required air pressure to perform correctly. The unit features an adjustment mechanism where you hold the spin button, pull it up, turn the rotary button to set the desired pressure, and press down to lock the setting in place. By helping to keep operating pressures under established limits, this regulator supports optimal tool performance and contributes to the longevity of your pneumatic equipment.

Engineered for practicality and convenience, this lightweight air pressure regulator is straightforward to install and remove within your existing setup. The included steel bracket provides added stability for the assembly while protecting the integrated pressure gauge during operation. Whether paired with an air compressor, air spray gun, or other pneumatic devices, this valve helps manage airflow reliably across various workshop tasks. The comprehensive kit includes the air pressure regulator itself, a pressure gauge, and a matching metal bracket to facilitate a secure installation.

Technical parameters for this model include an air inlet size of 1/4″ NPT and a rated flow of 550 L/min. It is built to handle a proof pressure of 217 psi (15 bar) and a maximum working pressure of 145 psi (10 bar), with an operation temperature range spanning 40–140 °F (5–60 °C). For ongoing maintenance, the manufacturer suggests the use of ISO VG32 Turbine 1 Oil for lubrication. This professional-grade accessory offers a dependable solution for managing compressed air systems and maintaining controlled pneumatic pressures during your projects.
