Abstract
A filtration assembly particularly for filtering fluid media such as compressed air is formed with a housing defining a fluid inlet and a fluid outlet and with a filter unit arranged within said housing to have the fluid media to be filtered flow therethrough. The filter unit is formed of a plurality of interchangeable filter elements joined together to form the filter unit by connecting devices including a head cover and a bottom cover arranged between juxtaposed ends of adjacent filter elements to mount said filter elements together in fluid tight relationship. The head cover is formed of a recess into which the bottom cover extends with a sealing ring being arranged in said recess in fluid tight engagement between the head cover and the bottom cover.
Claims7
A filtration assembly for filtering fluid media, particularly compressed air, comprising:
- housing means defining a fluid inlet and a fluid outlet;
- a filter unit arranged within said housing means to have fluid media flowing between said inlet and said outlet pass therethrough;
- said filter unit comprising a plurality of generally cylindrical filter elements each having an upper end and a lower end, said filter elements being joined together with the upper end and lower end of each adjacent filter element juxtaposed to form said filter unit as a generally hollow cylindrical body;
- seal means mounting said filter unit within said housing so that substantially all fluid media flowing between said fluid inlet and said fluid outlet passes through said filter unit;
- connecting means located at said juxtaposed upper and lower ends of said filter elements operatively mounting said filter elements together;
- said connecting means including a head cover having a central aperture mounted at the upper end of each filter element and a bottom cover having a central aperture mounted at the lower end of each filter element, with said head covers and bottom covers being positioned between adjacent filter elements to join said filter elements together;
- said connecting means including a closure for the lower bottom cover and groove passage means formed in each of said head covers and bottom covers, said groove passage means defining a flow path for liquid impurities to drain from said filter elements and to pass between adjacent filter elements.
