摘要： A coupling is provided for a pressure or vacuum fluid system having a bowl and filter head (10, 26) that connect together by relative rotation to engage bayonet coupling formations (32, 34, 94) thereof. When connected together the bowl (10) and filter head (26) have outer walls (16, 104) overlapping with an intervening seal (22) therebetween. A pressure relief valve (38) is provided in one of the members (10). A latch (36, 108) engages at an angular position of said members (10, 26) where the bayonet coupling is established to prevent relative rotation of said members (10, 26) and is prevented from engagement at other angular positions. The latch (36) is decoupled from the valve (38) when in its engaged state but is operatively coupled to the valve (38) when in a disengaged state to open said valve (38), fluid flow therethrough providing an audible warning when a pressure differential exists across the valve (38).

摘要： An assembly is provided of filter bowl (10), cartridge (12) and head (11) in which the filter bowl (10) can be removed after it has descended from the filter head (11) through a distance corresponding to only a minor part of the length of the filter cartridge (12). The cartridge (12) is a push fit into a vertical port (52) in the filter head (11). Flange (18) of the cartridge (12) and slotted buttress (44) of the bowl (12) establish a mechanical connection between the filter bowl (10) and the filter cartridge (12) so that the filter bowl (10) and the filter cartridge (12) are together mountable to and demountable from the filter head (11). The filter cartridge (12) having the support flange (18) that coacts with the buttress (44) is also claimed per se.

摘要： Gas at elevated temperature from a compressor (50) is fed to a first cooling coil (14) and thence to a second cooling coil (18) in chamber (16). The cooled gas at line (20) enters a chamber (22) where water and oil (if present) separate. A contaminant-free stream of compressed gas is further purified at filter chambers (28, 34). A portion of the gas flow, carrying the liquefied water or water/oil mixture is returned via reducing valve (44) to the interior of chamber (16) where it travels up riser pipe (46) in heat-exchanging relationship with the gas in coil (18) and emerges through port (48) as a condensate-free gas stream, the condensate having re-volatilised after passage through the reducing valve (44). The described arrangement minimises or eliminates watery waste and cools the gas stream without the need for a powered cooler or supply of cooling water.

摘要： A filter assembly comprises a cartridge (18) containing a filter or a body of adsorbent material and a filter head (17) into which the cartridge (18) is fitted. The cartridge (18) has an inlet port defined by spigot (22) and a body (24) of porous material in the spigot (22) that can trap liquid droplets entrained in a gas stream entering the head (17). The body (24) of porous material is impregnated with a dye responsive to the presence of liquid trapped by the trapping means by changing colour, as is a wick (26) communicating therewith. Colour change at the wick (28) is viewed from outside the filter head (17) through lens (30). By this means the presence of droplet contamination in the gas stream e.g. by reason of an abnormality upstream of the filter head (17) can either be made visible directly from outside the housing or can be detected by remote sensing means. The invention is particularly, but not exclusively, applicable to the detection of oil mist or droplets in an air stream from a compressor.

摘要： A closed hollow filter canister is provided which may comprise gas-impermeable end walls (94, 96) and a gas-permeable side wall (100). Gas contaminated with liquid is sprayed under pressure through line (90) and flow-restricting orifice (80) into the interior space of the canister where the contaminants become atomised and are retained by the side wall (100). Gas free of liquid contaminants passes into the atmosphere. In a preferred embodiment the gas is air contaminated with water, and the wall (100) is of cellulosic material which becomes wetted with water which gradually volatilises. The filter canister may be used to treat streams (90a, 90b) from a gas compressor (50) and an associated reservoir tank (125).

摘要： A gas and vapour permeable outer layer (17) is provided that has a conductive surface coating, and is used in a filter (1) to reduce the risk of fire and/or explosion. The filter (1) may be used to separate hydrocarbons from a gas stream entering the separator (1) through inlet (11). As the gas/hydrocarbon mixture passes through the matrix layer (9), the hydrocarbons coalesce to form hydrocarbon droplets that are transported in the outer layer (17) to the base of the filter (1), where they can fall under gravity into a sump (not shown). Static electricity is prevented from building up on the outer surface (18) of the filter (1) due to the conductive coating that has been applied thereto and therefore, the risk of fire and/or explosion is reduced.

摘要： A filter element which fits a filter head that is normally arranged for out-to-in gas flow through a filter cartridge has a pipe (32) defining with an upstanding wall of end-cap (16) a gas-tight inlet passage leading to a space (38) within the filter element (10). A return passage for filtered gas is provided by the pipe (32) which extends from an apertured end cap (18) of the filter element through the interior thereof to the first end, said arrangements changing the flow path to in-to-out. In use, in the case of a filter cartridge, it is less prone to give rise to blockages in a drain (55) of the filter housing which is less exposed to contamination with solid matter. In the case of an adsorbent filter, an indicator material can be provided which becomes visible on the exterior surface of the filter element on exposure thereof e.g. to oil droplets.
