The diverter has an input port proximate to a midpoint of a top of the diverter and diverter exit ports proximate to an outer perimeter of a bottom of the diverter.

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.

An air purification module which purifies introduced unpurified air and discharge purified air, includes a first filter supporter extending in a first direction and having a penetrating shape including a first hollow region, a first filter which is supported by the first filter supporter and penetrates a side portion of the first filter supporter, a second filter supporter extending in the first direction, having a penetrating shape including a second hollow region, and disposed in the first hollow region, a second filter which is supported by the second filter supporter and penetrates a side portion of the second filter supporter, and a light source module disposed in the second hollow region.

A portable air purifier may include a housing having an accommodation space formed therein and including an inlet through which air is suctioned and an outlet through which air is discharged, a filter installed at an inside of the housing that faces the inlet, a fan module installed at the inside of the housing that faces the outlet, a filter case in which the filter is detachably installed and which is disposed between the filter and the fan module and configured to guide movement of air from the filter to the fan module, and a sanitizing portion mounted on the filter case and configured to irradiate sanitizing light toward the filter.

Modular air filter assemblies having a configurable inlet, a configurable outlet, and a configurable mounting assembly are described herein. The modular filter assembly includes a tube extending along a central axis between a first end and a second end. The tube defines a curved surface. The modular filter assembly further includes an inlet extending radially outward of the curved surface relative to the central axis. The modular filter assembly includes two or more brackets. Each of the two or more brackets are configured to attach to a curved surface of the tube at a plurality of radial orientations relative to the central axis.

Modular air filter assemblies having a configurable inlet, a configurable outlet, and configurable mounting assembly are described herein. The modular filter assembly includes a tube, an aperture extending through a wall of the tube, an end cap at a first end of the tube, an outlet cap at a second end of the tube, and an inlet cap. The tube extends along a central axis from a first end to a second end and is configured to receive a filter. The inlet cap is configured to be fastened to the aperture in a first configuration and a second configuration, different from the first configuration. The inlet is in communication with the aperture in each of the first configuration and the second configuration.

The paint apparatus includes a paint booth having an upper chamber in which a painting operation is performed and a lower chamber placed below the upper chamber; a receiving portion 2 that receives air discharged from the paint booth; a filter module 3 attachable to and detachable from the receiving portion 2 and including filter portions 31 and 32 that trap paint mist from air that passed through the receiving portion 2, a filter inlet portion 33 that receives an inflow of air from the receiving portion 2, and a filter outlet portion 34 that discharges air from which the paint mist was trapped by the filter portions 31 and 32; and rails 6 that guide the filter module 3 to an attached position at which the filter module 3 is attached to the receiving portion 2.

The invention relates to a device for filtering air and creating an overpressure in a closed or semi-closed space, comprising at least one housing, comprising at least one air inlet and at least one air outlet, at least one ventilator for taking in air in particular via the at least one air inlet, at least one filter for filtering air which is drawn into the device, wherein the at least one ventilator and the at least one filter are received within the at least one housing and wherein the at least one housing is configured such that air drawn into the device by the at least one ventilator is pushed through the at least one filter towards the at least one air outlet.

A flat-filter filter element for filtering fluid has at least two areal filter medium bodies arranged axially adjacent to each other and arranged to be flowed through axially by the fluid sequentially. The filter medium bodies each have an outer circumference. A common circumferential lateral strip frames the filter medium bodies at their respective outer circumference. The filter medium bodies include a downstream filter medium body and an upstream filter medium body. The common lateral strip has a protrusion section that extends from the downstream filter medium body axially to the upstream filter medium body. A circumferential molded element is arranged at the upstream filter medium body. The common lateral strip is embedded at least partially in the circumferential molded element. The filter element is arranged in a filter housing of a filter system and the circumferential molded element seals first and second housing parts of the filter housing.
