Q01 Series Core. Robust proportions, open geometry.
INSIDE THE Q01 SERIES CORE
Lateral retention keeps the inflation assembly compact, frees space for larger buttons, and simplifies maintenance.
Metered air addition through the usable stroke keeps fine inputs clear and readable.
Two-stage actuation. HI-FLOW beyond a deliberate tactile threshold.
Poppet-retained O-ring. Conical seat. Progressive exhaust across four flow levels with higher capacity.
Progressive control. Deliberate HI-FLOW access. Oversized tactile controls.

DUTY-GRADE BUILD.
SECOND-GEN PISTON. Q-SHIFT DUAL-STAGE. BROADER OPERATING RANGE.
Q01 series introduces Q-Shift dual-stage actuation, gating HI-FLOW behind a deliberate second-stage step for capacity on demand.
Built on a Second-Generation Piston Architecture, it maintains a gradual, stable response as deposits build. Edge Lock System keeps inlet access compact and direct. Driven Seal Exhaust brings a smoother, more progressive release response to the system. Oversized 25 mm controls deliver positive tactile indexing and confident input under gloves.
A broader operating range, oversized actuation surfaces, and more control where it counts.

across a smooth ramp with four flow levels, plus a 350 L/min HI-FLOW stage.
Edge lock
RETENTION SYSTEM

Lateral locking keeps the inlet compact, supports larger buttons, and simplifies service access.

Exhaust Actuation Load: 3.0 kg
Firm, controlled venting input.

Exhaust Range & Progression
across a smooth ramp with four flow levels.
DRIVEN SEAL
EXHAUST SYSTEM

Driven seal exhaust. Poppet-retained O-ring, conical-seat sealing for improved stability.
PATENTED SYSTEM

A deliberate tactile threshold within the inflation stroke gates access to an extended second stage, preserving progressive control.
AVAILABLE SYSTEM CONFIGURATIONS
Specify your setup. Each HYDPRO Tek Range series is offered in three Actuation Core configurations: Metal, Technopolymer, and Non-Magnetic. Non-Magnetic also available to Military & Defence specification on a program basis.

Extended Mount Compatibility
Engineered for cross-platform integration, HYDPRO Power Units are available in T23 and T25 Mount Standards, specifically configured for 23.6 mm (0.93 in) and 25.4 mm (1.00 in) corrugated hoses.
CRAFTED FOR DEPTH. DRIVEN BY PERFORMANCE.
ITALIAN ENGINEERING.
PREDICTABLE CONTROL.
Each HYDPRO device is engineered and manufactured in Italy: one chain from raw material to release. Polymer families are selected for constant immersion, precision-drawn brass runs on in-house CNC lines, and every device leaves built, tested, and signed off under one roof.


Built to integrate. True to your setup.
Whatever the field runs, HYDPRO builds to it natively: every established mount standard, thread, and host geometry, covered from the factory. Your setup stays as it is, integration stays clean, and the response repeats: the same command, the same result, on every dive.
Proven by divers. Refined by decades.
Four decades in the water stand behind the current generation. What wears, what binds, what drifts out of tune comes back from real dives to the bench, and the next revision answers it. Control you can feel, refined one generation at a time.
