Compact 0.5L aluminium cylinder with triple-filter and fluorescent pressure gauge. DOT and CE certified, airline-approved when disassembled, with three refill methods.
Brief Emergency Air Supply - thanks to 0.5L portable cylinder
A half-litre 6061 aviation-aluminium cylinder stores compressed air that typically yields about 6-10 minutes of breathable supply depending on depth and breathing rate. Small diameter (6cm) keeps overall package compact.
Provides a short, dependable breathing window for quick underwater tasks such as mask-assisted inspections, brief rescues or hull cleaning during short stops.
Cleaner Breathing and Easy Monitoring - with triple-filter system and fluorescent pressure gauge
A triple-filter arrangement captures particulates before inhalation while a fluorescent pressure gauge presents remaining pressure clearly in low light. Both systems are mechanical and require no electronics.
Helps reduce the risk of inhaling contaminants and lets users check remaining air at a glance, improving safety during short dives.
Portable and Refillable - thanks to airline-friendly disassembly and multiple refill options
Design allows safe disassembly for travel and supports refilling via electric compressor, manual pump, or transfer from a larger bottle at 3000 Psi / 200 Bar / 20Mpa. Refill flexibility suits different field situations.
Easier to transport and top up between sites, making the kit practical for mobile teams and remote tasks where full scuba facilities are unavailable.
