When every second counts, search and rescue and emergency teams need a fast, reliable way to inflate lifeboats. NRS Rapid Fill Kits attach to standard air tanks to inflate boats in less than three minutes. Inflation time varies depending on overall size, but on average it can inflate a raft in less than 3 minutes. The heavy duty hose can withstand up to 5,000 PSI. Includes a Leafield pressure valve adapter that will work on C7 and D7 valves. As an added precaution, the threadless valve adapter can be quickly released in case of over-inflation. The SCBA Quick Fill Kit screws onto a standard SCBA tank thread. the Scuba Yoke quick fill kit fits standard scuba tank threads. The DIN quick fill kit fits European style scuba tank threads. SCBA and Yoke kits include a flow restrictor fitting to limit airflow for added safety. Flow reducer fitting integrated into the DIN quick fill kit. Kits include a hose, valve adapter, and tank connector. An air tank is not included. NRS quick fill kits only work on standard tanks. If your service uses a quick-release adapter, these will not work without aftermarket additions. Recommended for professional use only. Risk of injury and damage to inflatable structures is high.
