HDRX-030
The HDRX-030 is the workhorse of the MEYER range: a 3-litre, 300 bar Type IV cylinder at 1.6 kg — roughly a third of the aluminium equivalent — with no limited lifespan (NLL). It flies on fuel-cell and pneumatic UAVs, rides on robotics and UGV platforms, backs SCBA and rebreather rigs, and feeds mobile labs and test benches, filling daily for years without a retirement date.
Like every classic HDRX it is underwater-rated, matt black, and available in dedicated variant part numbers: -MIL for STANAG 2897 Class A non-magnetic EOD/MCM configuration and -HE with the MEYER sealed liner for helium service with no measurable permeation.
