Breathe underwater.
No tank required.
Battery-powered surface air that floats above you — up to 10 hours and 29 m on a single charge. Charge it at home, carry it with one hand, dive all day.
Your air supply floats above you.
A sealed, battery-powered compressor rides on the surface and sends clean, oil-free air down a coil hose to a standard regulator. Nothing on your back but a light harness.
A CATL lithium pack powers a brushless, oil-free compressor inside a self-righting hull that resets in one second if flipped.
63–160 L/min of filtered air flows through a kink-resistant coil hose, 12 to 30 m long.
A familiar second-stage regulator delivers air on demand. Swim, hunt or work — for hours.
Four depths. One idea.
Every WOLACH shares the same oil-free air path, CATL battery and 2-year warranty. Choose by how deep and how long you dive.
How deep do you dive?
Drag to your usual depth. We'll show which systems are rated for it — rated, not lab-tested, because that's the number you should plan around.
From reef walks to working shifts.
Reef & recreation
Unhurried hours on shallow reefs without watching a gauge.

Scuba Tank vs. Tankless Hookah Diving: The Complete 2026 Comparison
Cost, bottom time, depth, safety and logistics — an honest, side-by-side look at when a surface-supply system beats a tank, and when it doesn’t.
How Deep Can You Go With a Hookah Diving System?
Rated depth vs. tested depth, why hose length is not depth, and the no-decompression limits that still apply.
