What is ExtendAir® Cartridge (EAC)?

ExtendAir® is the brand name for Micropore's CO2 absorbent filtration cartridges and canisters.  Micropore uses the same basic chemistry found in granule CO2 absorbents, calcium hydroxide and a small amount of potassium and sodium hydroxide (chemical composition information can be found on material safety data sheet). Micropore blends these chemicals along with a small amount of polyethylene (plastic binder) into a molded sheet of material with raised ridges on one side and flat sheet on the other side of the material.  The sheet is then wound (rolled) on a plastic center core to a cylindrical cartridge meeting diameter and height requirements specific to the ExtendAir® capable rebreather.  Cartridges are kept tensioned as a cartridge roll of material with a heat-staked clear film wrap.  The EAC features high CO2 absorbent performance (liters CO2/lb absorbent) and low resistive effort (reduced work of breathing for the diver) in addition to adding safety via its molded sheet and elimination of caustic dust entering the breathing loop.
 

MODE Cartridges come in case of (4) cartridges.
 

Diver Features and  Benefits Include:

Diver Safety: 70% less caustic even after 5 minute flood

No Dusting, No Spillage: 

    • No absorbent gets in the breathing loop.

    • Platform friendly (submarine, rib, ships quarters, etc.)

    • Eases maintenance logistics: no more perforated screens getting clogged

Storage: Absorbent can be stored with rebreather instead of separately in bulk containers; single-use packaging also reduces wasted absorbent

Reduced Diver’s breathing workload

Excellent tolerance to storage, shock, vibration

No settling: Consistent scrubber duration; no absorbent bypass or channeling
