HOUVAN 0.5L Mini Scuba Tank, Green, Tank Only (No Inflation Equipment) — 3000 PSI, DOT Certified with 5KG Valve

The HOUVAN Mini Scuba Tank is a DOT-certified 0.5L reusable pony bottle that provides a compact backup air source for shallow diving, underwater shooting, and emergency rescue situations.

Compact and engineered for portability, this HOUVAN 0.5L scuba tank is built from aviation-grade aluminum with a food-grade silicone mouthpiece and a 5KG explosion-proof valve. Designed for short-duration use, it gives divers a measured reserve of breathable air in shallow water operations and can also serve as a convenient tool for boat inspection, treasure hunting, or rapid-entry rescue work. The tank meets DOT certification and offers multiple inflation options to suit different users and environments.

How much air does the 0.5L HOUVAN tank actually provide?

Tested at 200 bar, the 0.5L HOUVAN mini tank can supply roughly 35 full breaths under controlled shallow conditions. Real-world performance varies with breathing rate, diver skill, depth, and temperature—so monitor the gauge and plan conservatively.

• Nominal capacity: 0.5 liters (3000 PSI / 200 bar working pressure).
• Approximate breaths: ~35 at 200 bar in testing to 16 ft depth.
• Actual duration depends on exertion, depth, and individual breathing.

What safety features and materials are included?

The bottle body is precision-machined from aviation-grade aluminum and uses a food-grade silicone mouthpiece for hygiene and comfort. A 5KG explosion-proof valve and DOT certification improve safety, and the valve’s fail-safe will release gas at specified overpressure limits; any damaged safety components must be replaced before use.

• Aviation aluminum construction for strength and corrosion resistance.
• Food-grade silicone mouthpiece for user comfort and cleanliness.
• 5KG explosion-proof valve (replace if damaged) and DOT certification.

How do I refill the HOUVAN mini tank?

HOUVAN offers several inflation methods so you can choose based on convenience and available equipment. Certified divers can top up at dive shops; HOUVAN also provides an adapter for fast fill, a portable compressor option, and a manual hand pump as a backup.

• HOUVAN filling adapter: quick fill in about 4–8 seconds when used with an appropriate source.
• HOUVAN air compressor: fills in roughly 11 minutes for field or home use.
• Hand pump: 25–30 minutes; recommended as an emergency backup only.
• Working pressure rating: 3000 PSI / 200 bar / 20 MPa.

What depths and activities is this mini tank suitable for?

The HOUVAN 0.5L is intended as a short-duration reserve for shallow-water tasks and emergency breathing support. Manufacturer guidance frames primary operation around shallow depths (up to 16 ft), with the tank usable as an emergency backup at greater depths when planned accordingly.

• Primary recommended shallow use: up to 16 ft for regular operations.
• Backup/emergency use: may be used to support brief ascents from greater depths with caution.
• Typical activities: leisure snorkeling, underwater photography, boat or hull inspection, shrimp catching, treasure hunting, and rescue entry.
• Removable bottle head and valve allow air-side transport compatibility with airlines—verify current airline rules before travel.

Who this product is for: The HOUVAN Mini Scuba Tank is aimed at experienced divers and trained first-responders who need a lightweight, DOT-certified pony bottle for short emergency air reserves or specialized shallow-water tasks. It’s also suited to underwater photographers, boat technicians, and recreationists who require a compact, refillable air source—provided users follow filling, inspection, and depth guidance and only operate within their training and local regulations.
