The regulator is the brain of your HPA setup. It takes 3,000+ PSI from the tank and delivers a stable working pressure to your engine — get this wrong and the rifle never shoots right.

HPA tanks store air at 3,000 PSI for aluminium tanks or 4,500 PSI for carbon fibre. HPA engines run on a fraction of that — typically 60 to 140 PSI depending on the platform. The regulator is the component that bridges those two pressures and holds the output stable shot after shot. A regulator that drifts even 5 PSI under rapid fire will give you visibly inconsistent FPS readings on a chrono and unpredictable hop performance in the field.

Three regulator families cover the UK market. The HK Army Hostile range (V2, XLP, and the latest LPR variants) is the paintball-derived workhorse — tournament-proven, externally adjustable, and the most common regulator on UK speedsoft rigs. The Wolverine Storm (Cat 5 and Cat 9) is built specifically for airsoft, with output ranges and adjustability tuned for the lower-pressure engines used in MTW and Article platforms. The Airtac AT200 is our value pick — solid build, reliable output, and a price point that suits a first HPA setup.

Pair the regulator with the right tank, the right line, and the right engine for your platform. If you're unsure what output pressure your specific rifle wants, the HPA tech service can set this up for you before dispatch.

💡 Titan Forge tip: Match your regulator to your engine — Wolverine INFERNO engines run happily at 90-100 PSI, GATE PULSAR runs lower. Set output too high and the engine wastes air; too low and you get partial cycling. The right pressure is the one the manufacturer specifies, not the highest your regulator can deliver.
