Spare Air

About

Spare Air — Emergency Air When It Matters Most A dive emergency rarely announces itself in advance. A free-flowing regulator, an out-of-air situation, or a panicked buddy needing to share can happen at any depth, at any point in a dive. Spare Air exists to give you an independent air supply when your primary source fails — not as a substitute for good dive practice or a properly configured primary regulator, but as a genuine backup that may be the difference between surfacing safely and a serious incident. Spare Air's system is compact enough to clip to your BCD without adding meaningful drag or bulk, and refills directly from any full scuba tank in seconds — you don't need specialized equipment or a separate air station. At DiveCatalog.com, we carry the current Spare Air lineup as an authorized dealer. The Spare Air Range 300PK-DG — Standard Air with Dial Gauge The standard Spare Air package: a 3.0 cu ft (85 liters) aluminum, black-anodized cylinder with a balanced single-stage regulator delivering steady air when you need it most, plus a dial gauge for easy pressure monitoring. Includes the Spare Air unit, holster, safety leash, and refill adapter. Refills from any full scuba tank in seconds. 300PK-N and 300PK-NDG — Nitrox Versions The same 3.0 cu ft platform, cleaned and configured for use with Nitrox breathing gases. The NDG version adds the dial gauge for pressure monitoring; the N version is the base unit (gauge sold separately). Both include the holster, safety leash, and refill adapter. 600PK-NDG — Larger Capacity Nitrox The 600PK doubles the capacity to 6.0 cu ft (170 liters), providing significantly more air for a longer ascent in an emergency — a meaningful difference in a genuinely deep or extended dive scenario. Weighs under 4 lbs, still light enough to go unnoticed during a normal dive. Includes the Nitrox dial gauge, holster, safety leash, and refill adapter. Why Buy Spare Air from DiveCatalog.com?
