PneumaticPlus SAR400-N04BG Compressed Air Pressure Regulator, 1/2" NPT

Description

The PneumaticPlus SAR400-N04BG is a general-purpose, relieving-type compressed air pressure regulator — commonly called an air compressor regulator — built to reduce high, fluctuating supply pressure to a stable, usable level downstream. Rated at 180 SCFM through 1/2" NPT ports, it holds your set pressure steady as demand rises and falls, protecting tools and delivering consistent performance across your shop or production line. The relieving design is the safest, most common choice for compressed air: if downstream pressure ever climbs above your setpoint, the regulator automatically bleeds off the excess to protect your equipment. A push-to-lock adjustment knob lets you dial in any pressure across the 0-150 PSI regulating range and then locks it in place, so vibration and busy hands on the shop floor never knock your setting off target. Maximum supply pressure is rated at 250 PSI. As a dependable general-purpose air line regulator, it suits air tools, spray equipment, actuators, cylinders, and everyday pneumatic machinery — anywhere a clean, controlled working pressure keeps equipment running its best. Every SAR400-N04BG ships ready to install with a 0-160 PSI pressure gauge and a panel/wall mounting bracket, so there is nothing extra to source. It is precision manufactured in Korea to ISO 6953 standards and backed by a 1-year limited manufacturer warranty and responsive PneumaticPlus support — giving professionals, contractors, and industrial buyers a regulator they can specify with confidence.
