Abstract
A vent filter (1), preferably for a pure liquid storage tank, comprising a cylindrical shell (2), at least one compartment (A) for accommodating granular filter material (3), said at least one compartment (A) defined between an inner peripheral surface (4) of the shell (2) and a pair of spaced apart separator plates (5) arranged in the shell (2) such that the spacing of the separator plates (5) in the axial direction of the shell (2) can be changed and fixed so as to apply a pressure on the granular filter material (3) in the at least one compartment (A). An air inlet (6) and an air outlet (7) are respectively arranged to allow a flow of air through the granular filter material (3) in the at least one compartment (A).
Claims15
A vent filter, comprising:
- a cylindrical shell;
- at least one compartment for accommodating granular filter material, said at least one compartment defined between an inner peripheral surface of the shell and a pair of spaced apart separator plates arranged in the shell such that the spacing of the separator plates in the axial direction of the shell can be changed and fixed so as to apply a direct pressure on the granular filter material in the at least one compartment;
- and
- an air inlet and an air outlet respectively arranged to allow a flow of air through the granular filter material in the at least one compartment;
- said vent filter further comprising a support member extending in an axial direction of said cylindrical shell and a locking mechanism for allowing fixing of at least one of the separator plates in a plurality of defined positions in the axial direction of the shell on the support member.
