摘要： A compact respiratory protective device fitted with a mouthpiece or mouthpiece assembly that retracts, pivots or rotates into the depth of the device to reduce size when packed. This reduction in size also permits the depth of the downstream air channel to be increased while still producing a compact device. This increase in the depth of the downstream air channel maximizes the efficiency and capacity of the filter assembly and reduces the inhalation resistance of the device. The reduced breathing resistance enhances usability.

摘要： A respiratory protective device in which a face piece (11) is located within the volume of a filter canister (10). The filter canister (10) can be in the form of a hollow section or sections which fit around all or part of the face piece (11) or on either side thereof. Contaminated air that has been purified in the filter canister (10) is ducted in an airtight manner through a hollow assembly (18) into the face piece (11).

摘要： A filter unit for use in a filter box assembly, the filter unit comprising a particulate filter layer and a gas filter layer, the particulate filter layer being configured to bias towards the gas filter layer, exerting pressure thereon. There is also described filter box assemblies (including a duel filter assembly) comprising the filter unit, and a respiratory protective device comprising the filter unit. Also described is a method of manufacturing a filter unit with a gas filter layer and a particulate filter layer, wherein a force is applied to the particulate filter layer causing it to fix the gas filter layer in place. Also described is a method of manufacturing a dual filter assembly wherein a casing is twice reversibly attached to and detached from a support surface, filter units being added to the casing when the casing is attached to the surface.
