1.3 OPTIONAL EQUIPMENT
1.3.1 CONTAMINATION CANISTER
The scrubber fan unit can be installed with a contamination canister (2.80.3963). The IHC Hytech
contamination canister removes contamination from breathing gas in enclosed environments. The
special fill of the canister removes all kind of contamination in enclosed environments such as
vomit, urine, feces and sweat.
The following chemical components are eliminated:
• Urea (NH2) 2CO from urine
• Carbon monoxide (CO) from endogenous production
• Acetone (GH3 COCH3) metabolic and from organic waste
• Hydrogen chloride (HCL) from vomit
• Hydrogen sulphite (H2S) from feces/intestinal gas
• Carbonyl sulphite (OCS) from intestinal gas
• Hydrogen (H) from intestinal gas
• Methane (CH4) from intestinal gas
• Carbondisulphite (CS2) from intestinal gas
• Butyric acid (C3H1COOH) from intestinal gas
The contamination scrubber canister contains a special blend of carbon molecular sieves and a
catalyst and is stored in an air tight container. Once the container is opened and the canister is
exposed to the environment it starts to work. The canister lasts for at least 450 hours/person.

NOTE
The duration of a canister is calculated as follows:
450 divided by the number of occupants = hours of duration.
Example: A hyperbaric life boat is occupied by 18 persons. The duration of one canister is 450
divided by 18 occupants = 25 hours.
