摘要： A filter housing adapted to be mounted in an air ventilation system, which filter housing has: an upstream air entrance opening defined by an air entrance opening frame, a downstream air exit opening defined by an air exit opening frame and located opposite of the air entrance opening, a rear wall extending between and attached with the air entrance opening frame and the air exit opening frame, a front opening opposite to the rear wall, the front opening being defined by a front opening frame, and a cover sealing the front opening when the cover is closed; a movable filter holder arranged within the housing and arranged to receive a filter through the front opening; and two clamping mechanisms arranged at opposite first and second walls of the housing, which first and second walls extend between the entrance opening frame and the exit opening frame, each clamping mechanism being connected with the filter holder to clamp the filter in a clamped position. Each clamping device has a release device engaged with the filter holder, and is arranged for releasing the filter from the clamped position to a released position by moving the filter holder. The release device has a handle arranged at the front opening. Each handle is arranged to be in a locked state when the filter is in the clamped position, unlocked by being pulled out a distance, and then rotated to a release position in order to release the filter.

摘要： There is provided a frame assembly 200 adapted for installation in a filter housing of an air handling system. The frame assembly is arranged having a frame 210 which is adapted to receive a filter unit of a predetermined size. The frame assembly further comprises a clamping mechanism 230 arrange for clamping the filter unit. An actuator 231 of the clamping mechanism is arranged at a front member 211 of the frame and is operable between an open and a closed position while activating the clamping mechanism to clamp the filter unit. An actuator element 232 facing a back member 212 of the frame is arranged such that a free distance between the actuator element and the back member during operation of the actuator corresponds to the predetermined filter unit size, thereby enabling operation of the actuator only if an inserted filter unit abuts the back member of the frame.
