Avon Protection FM61 CBRN Filter Pair 

These low profile filters are supplied as a pair and are designed with bayonet quick fit for use only with the FM50 mask.

• The twin filter design significantly reduces breathing resistance and improves weight distribution.

• The filters provide protection from CB agents, toxins, and a number of Toxic Industrial Materials/Chemicals (TICs/TIMs) such as particulate matter including radioactive hazards, chlorine, hydrogen sulphide, sulphur dioxide and organic vapours with a boiling point above 65°C.

• FM61 Filters can be replaced without breaking the protective seal through self-sealing connections.

Construction materials

a) The canister body is made of Noryl, a Polyphenylene ether/polystyrene synthetic thermoplastic polymer. It produces a very robust product, providing extreme durability against shock and impact in operational use. The canister body is black in colour.

b) Gas adsorption is by activated charcoal granules impregnated with metallic salts of copper, zinc, molybdenum and silver to react chemically with agents such as hydrogen cyanide and cyanogen chloride. Excellent protection is provided against physically adsorbed gases such as the nerve agents (“G” and “V” series), mustard gases, phosgene and chloropicrin (see overleaf).

c) The high efficiency particulate filter element is made of PTFE, PET/PE fibres.

d) The FM61 Filter is non-ferrous and non-magnetic.
