Abstract
A filter pack comprises a first housing member (1) having an inlet port and an outlet port (4) for compressed air; the outlet port being connectable to a piece of equipment, for example a spray gun. A second housing member (6) is removably fitted into the first housing member through an opening (5) therein and has a section (8) protruding from the opening. A retaining ring (12) releasably secures the two housing members together. The second housing member is at least partially filled with activated carbon filter material (18). A wall area (19) of the second housing member is formed with an inlet into the interior thereof, and the wall area combines with part of the first housing member to form a chamber (15) in communication with the inlet and outlet ports. The protruding section (8) of the second housing member has an outlet (9) for connection to an airline, the flow path from the inlet port to the outlet of the second housing member being through the chamber and then through the filter material. The outlet may be connected to a breathing mask by way of a regulator assembly (23).
