Embodiment Construction

[0035] exist figure 1, a filter unit 1 realized as a filter cartridge is shown in a schematic manner, which is inserted into the return or exhaust duct 2 of a barrier system 3, which is preferably realized as a pharmaceutical isolator and includes a processing Room 4. The filter unit 1 has a substantially cylindrical design, and in figure 1 is shown in longitudinal cross-sectional view. figure 1 A central longitudinal axis A is shown, in the present case in the form of a longitudinal center axis, which extends along the direction of longitudinal extension of the filter unit 1 and corresponds to the shown for inserting the filter unit at the barrier system 3 . The insertion direction or axes in the location are coincident. The longitudinal axis A passes through the front opening 6 of the filter unit 1 through which gas (in this case air) can flow axially from the treatment chamber 4 into the interior 7 of the filter unit 1 (when the opening 6 is open), From this interior 7 ...

Abstract

The invention relates to a closure device (28) for a filter unit (1) for the mutual and releasable insertion into a return air duct or exhaust air duct (2) of a barrier system (3), comprising a main body (30), an opening (6) in the main body (30) that can be peripherally bounded by an annular seal (11), a lid (10) that can be switched between an open position in which the opening (6) is open and aclosed position in which it bears in a sealing manner against the annular seal (11) in order to selectively open and close the opening (6) and that has passing through it an imaginary longitudinal axis (A), wherein the lid (10) is connected in an articulated manner to the main body (30) so as to be able to pivot by means of at least one rotary articulation (40) through which there passes a pivotaxis (S). The lid (10) is designed so as to be able to pivot at least double-eccentrically, wherein the first eccentricity arises from the fact that the pivot axis (S) is arranged at a distance (A1) from a plane (E1) in which a closure section () of the lid (10) lies, and wherein the second eccentricity arises from the fact that the pivot axis (S) is arranged at a distance (A2) from a vertical longitudinal mid-plane (E2) which passes vertically through the center of the lid (10) when the latter is in its closed position.

Description

technical field [0001] The present invention relates to a closure for a filter unit intended to be engaged and removably inserted into a return or exhaust duct of a barrier system, the closure comprising: a body; an opening in the body , the opening can be circumscribed by an annular seal at the circumference; a cover, the cover can be shifted between an open position and a closed position, so as to selectively open and close the opening, wherein in the open position the opening is open, in the In the closed position, the cover is in sealing contact with the annular seal and the imaginary longitudinal axis passes through the cover, the cover being hingedly connected to the body so as to be pivotable by means of at least one swivel joint through which the pivot shaft passes. [0002] The invention also relates to a filter unit intended to be removably inserted into a return or exhaust duct of a barrier system. [0003] Furthermore, the invention relates to a barrier system, in...
