The plate group is housed in the housing region with the a sealing profile engaged with the wall and the contact profiles engaged to the contact elements. The sealing profile or contact profiles are shaped/positioned at variable vertical distances relative to an imaginary extension plane.

A filter module, including a plurality of filter elements for separating overspray from an air flow, the filter module including a reusable and cleanable frame configured as a support structure for components for collecting overspray, and a plurality of components inserted into the frame for collecting overspray, wherein the components for collecting overspray are at least filter elements and linings in the frame, which are configured as disposable, single-use products the filter elements form at least a first filter stage, and all the surfaces of the frame which are exposed to the air flow upstream of the first filter stage are provided with the linings such that the surfaces of the frame are protected against overspray.

Filter apparatus (6) in particular passenger compartment filter apparatus, for example for a motor vehicle (1), comprising a filter element (8) having a filter medium body (9) and a frame (10) surrounding the filter medium body (9), wherein the frame (10) features opposite lateral surfaces (11, 12), a plurality of engagement elements (22a to 22d), and a filter housing (7) featuring, on two opposing wall sections (24, 25), in each case two engagement counter elements (28a to 28d) in which in each case one of the plurality of engagement elements (22a to 22d) can be accommodated in a positive fitting manner, wherein the engagement counter elements (28a to 28d) in each case are designed as a groove in the respective wall section (24, 25) of the filter housing (7) and feature: an insertion section (31) which, when the filter element (8) is mounted in the filter housing (7), permits an insertion movement of the respective engagement element (22a to 22d) substantially along the throughflow direction (L), and a locking section (32) connected to the insertion section (31) and angled with respect to the insertion section (31), wherein a respective engagement element (22a to 22d) is disposed on a respective lateral surface (11, 12) of the filter element (8) when the filter element (8) is mounted in the filter housing (7), extends away from the filter medium body (9), and is held in a respective locking section (32).

A dryer is disclosed. The dryer comprises: a main body including an exhaust port; a first drying chamber disposed inside the main body such that hot air is supplied thereto; a second drying chamber disposed inside the main body such that hot air is supplied thereto; and an exhaust unit for guiding, to the exhaust port, air inside the first and second drying chambers, wherein the exhaust unit includes: a first exhaust path for connecting the first drying chamber and the exhaust port; a second exhaust path for connecting the second drying chamber and the first exhaust path; and a filter assembly separably coupled to the main body, and filtering the air passing through the first and second exhaust paths.

The invention pertains to a filter retaining assembly which is rigid and self-supportive without requiring any additional structural reinforcement. The design maximizes the filter surface to be used for air filtration and increases the filtration efficiency. The invention is also designed to minimize the filter assembly size to fit into the valuable space when the air handling unit physical dimension is constrained. The invention uses integral construction methods to save assembly time and labor by eliminating the need of using alignment holes and fastening each individual frame to construct a conventional filter retaining assembly. The proposed method maintains flexibility of scaling to any filter size and quantity.

An air purifier including a body including a suction port and a discharge port disposed on opposing surfaces thereof, and having an inner space through which air flows from the suction port to the discharge port, a fan disposed in the inner space and having a side surface separated from an inner wall of the body, at least one light source module disposed in the inner space to emit UV light, a power controller mounted on the inner wall and connected to a power source to supply electric power to the light source module, a cover mounted on the inner wall to cover the power controller, and at least one filter disposed in the inner space of the body, in which the cover includes a tilted air flow guide facet to guide tilted to allow air suctioned through the suction port toward the filter.

Disclosed is a filter conditioning unit for cleaning and conditioning high-volume sampling (HVS) filters. The unit includes, among other elements, a filter tray suitable for holding one or more HVS filters, a manifold in which the filter tray is inserted, and an optional enclosure for safety. The manifold is suitable for heating the filter tray and filters therein to a desired temperature while purge gas is introduced to the manifold. Also described herein is a method of using the filter conditioning unit.
