PowAir HPA Tank Regulator MAXREG 300 Bar / 4500 PSI - Black

HPA Regulator MAXREG for Bottle 300 Bar / 4500 PSI by PowAir

HPA regulator MAXREG by PowAir is designed for reliability, safety, and top-level performance of HPA weapons. With PI certification, it meets strict European standards and delivers a working pressure of 300 Bar / 4500 PSI. The default output pressure is 850 PSI, adjustable via shim system to 600 PSI or 450 PSI. Unlike spring-based models, MAXREG uses washers for longer lifespan and consistent performance. Orange O-rings indicate the 300 Bar version; green ones are used for 200 Bar systems. Both versions feature dual colored O-rings for improved sealing and easy identification. The build includes a micro fill nipple with filter, a 20mm black micro gauge with PowAir logo, and protective parts such as a rubber nipple cap and plastic thread cover. Delivered in a sturdy printed box, ready for bottle installation. For a fully functioning HPA system, you still need a low-pressure regulator like MaxFlow by EPeS.
