Embodiment Construction

[0041] figure 1 A compressor 1 is shown comprising a compressor element 2 with a gas inlet 3 and a compressed gas outlet 4 . The compressor element 2 is driven by a constant speed motor or a variable speed motor 5 .

[0042] In the context of the present invention, compressor 1 should be understood as the entire compressor arrangement, including compressor element 2 , all typical connecting pipes and valves, the casing of compressor 1 and possibly a motor 5 driving compressor element 2 .

[0043] In the context of the present invention, a compressor element 2 is to be understood as a compressor element housing in which the compression process takes place by means of a rotor or by a reciprocating movement.

[0044] Furthermore, the compressor element 2 may be selected from the group consisting of screws, teeth, jaws, scrolls, rotating vanes, centrifuges, pistons.

[0045] back now figure 1 , the compressor 1 further comprises a separation vessel 6 arranged on the compressed ...

Abstract

The present invention is directed to a filter assembly comprising a housing (15) and a filter cartridge (10), whereby the housing comprises (15) a housing inlet (16) and a housing outlet (17), the filter cartridge (10) comprising a filter inlet (11) fluidly connected to the housing inlet (16) and a filter element (12) provided between a top cap (18) and a bottom cap (19), whereby the bottom cap (19) comprises the filter inlet (11), whereby the top cap (18) and the bottom cap (19) create a circular or predominantly circular guiding system, and whereby the bottom cap (19) farther comprises a first part (19a) that receives the filter element (12) and a second part (19b) that is connected with a mating surface (20) of the housing (5), characterised in that the second part (19b) comprises a first circular section (21a) and a second section (21b); and that the first section has another shape than the second section (21b), such that the bottom cap (19) cannot rotate in relation to the matingsurface (20).

Description

technical field [0001] The present invention relates to a filter assembly comprising a housing and a filter element for separating liquid from compressed gas, the filter element being disposed within the housing, the housing comprising: [0002] - a housing inlet adapted to be fluidly connected to a compressed gas outlet and [0003] - the housing outlet from which the purge gas is recovered, [0004] The cartridge includes a filter inlet fluidly connected to the housing inlet and a filter element disposed between a top cover and a bottom cover also forming part of the cartridge, the bottom cover including the filter inlet, wherein The top cover and the bottom cover form a circular or predominantly circular guide system for mounting the filter element, and wherein the bottom cover further includes a first portion that receives the filter element and is connected to a second portion of the mating surface of the housing. Background technique [0005] Liquid separation filte...
