Couldn't load pickup availability
The PowAir MAXREG HP Regulator is a high-performance pressure regulator offering professional-grade features at an unbeatable price. PI-tested and built with precision, it delivers the consistency, adjustability, and durability serious players demand.
Unlike most regulators that rely on springs, the MAXREG uses shims—offering superior shot-to-shot consistency and virtually no wear over time. You can tune your output pressure easily by removing shims:
-
850 PSI (default)
-
600 PSI (remove 2 shims)
-
450 PSI (remove 3 shims)
The double ASA O-rings enhance air seal and come color-coded by pressure rating (Orange for 300 Bar / 4500 PSI, Green for 200 Bar / 3000 PSI). The fill nipple is equipped with a microfilter to prevent dirt and debris from reaching your tank, and the 20mm micro gauge keeps your readouts clear and compact.
This regulator comes fully loaded:
-
Tool-free pressure adjustment
-
All-black aesthetic on gauge and burst disks

Rubber fill nipple protector

Threaded transport cap
