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. Review: Home compressor regulator - Update 10/19/2022: I contacted the company and spoke with Richard who wanted me to check and see if it was installed backwards (air flow). I was pretty sure that was not the issue since I just piped my garage and installed two other filter/regulators without any issues. Well, went home and checked it and sure enough it was installed backwards. Switched it around and pressurized the system and all is good, no leaks. This does seem to be a well-made product and I expect it to last quite a long time. Customer service is what usually separates one company/seller from another and they were quick to respond when contacted. I'm glad it was a simple fix and I didn't have to go through the returning or refund to purchase another one. Purchased this for my home compressor that I just completed the max line install. This thing leaked from day one. I lowered the pressure and locked it down which stopped the initial leak. This system isn’t used much at the moment so a few weeks went by and today I aired up the compressor and this thing started leaking like crazy. I guess I’ll try to contact the seller and look into a refund or replacement. I know there are always bad items no matter who manufactures something so hoping this isn’t a real quality control issue. We will see how this goes. I’ll post back if this gets handled or not. Review: Great regulator great price - This is the second regulator I’ve bought from Pneumatic Plus. Very happy with both regulators. Heavy duty feel to them and they appear to be well made. No leaks after install and pressure gauges measure pretty accurate. I can’t see spending hundreds of dollars on a top of the line regulator for just being a home hobbyist and amateur bike builder. I’ve tried a number of different regulators for my 60 gallon Ingersoll Rand Compressor most have resulted in failure after a few months even as little as 1 day. If I need any more regulators in the future Pneumatic Plus will be my first choice.
