The invention relates to a filter module for trapping overspray from booth air laden with overspray from coating facilities, particularly from painting facilities, having a module housing, in which a filter structure (88) is accommodated and which has a module inlet (74) and a module outlet (76), wherein the filter module (40) is designed in such a manner that it is swapped for an empty filter module (40) once a limit loading of overspray is reached. The filter module (40) comprises a recyclable reusable structure (112) of one or more reusable components that can be thermally regenerated and therefore the filter module (40) can at least partially be thermally regenerated. The invention also relates to a trap having one or more filter modules of this kind, a coating facility for coating objects (14) and to a method for operating a coating facility.

An air cleaning or purifying system includes a main air cleaner or purifier having an upper seating surface that is at least partially flat and at least one portable air purifier having a base configured to be seated on re lifted from the upper seating surface. The main air purifier and the portable air purifier may each have a filter and a fan. The air main and portable air purifiers may operate together. The portable air purifier may be moved to another room, or may be seated on the main air purifier such that various combinations of air purifying modes and air purifying capacities may be performed.

Mist and vapor eliminating filters, devices, methods of filtering aircraft air using the devices, and systems including the devices, are disclosed.

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.

An air cleaner includes a first air cleaner having an output part, a second air cleaner configured to be electrically connectable to the first air cleaner, a power adapter detachably provided to supply power to the second air cleaner, a first input terminal provided in the second air cleaner and configured to be electrically connected to the output part, a second input terminal provided in the second air cleaner and configured to be electrically connected to the power adapter; and a switch configured to electrically connect the first input terminal to the output part or to electrically connect the second input terminal to the power adapter.

A filtering apparatus having a housing with lateral, upstream and downstream walls, and a top plate disposed at a significant angle to incoming overspray air to accelerate and guide the particulate-laden air. The angle of the top plate directs the air upstream and away from the filters so the larger solids impact the top plate and wall and adhere, removing paint from the air. Larger solids too massive to turn while accelerating through an opening into an entry chamber collect on the upstream sidewall and the highly filtered air flows toward filter units disposed downstream of the entry opening. Lighter solids that flow downstream are removed by the filtration media. An overhang of the angled top plate reduces flow into the filter units of collected solids.

An air filter arrangement (A) includes at least two frames removably attached to each other, each one of the at least two frames delimiting one of at least two spaces/volumes (V1, V2, V3) and all of the at least two frames together defining an air flow path (V1-V2-V3) passing through each one of the at least two adjacent/contiguous spaces/volumes (V1, V2, V3), wherein the space/volume (V1, V2, V3) of one frame of the at least two frames includes a first air filter (F1), the space/volume (V1, V2, V3) of another frame of the at least two frames includes a second air filter (F2), and the space/volume (V1, V2, V3) of one frame of the at least two frames includes an air moving unit (M1). A combined air filter arrangement (CA) may include at least two such air filter arrangements.

The present disclosure relates to a method for making a ceramic mini-tube configured for use in a fluid modification system. The method involves using an electrospinning system to receive a quantity of precursor solution. The electrospinning system creates an electric field which causes the precursor solution, when emitted, to be stretched into a fiber jet. The fiber jet is deposited on a collector resulting in a fiber mat. The fiber mat is removed from the collector, wherein the fiber mat is formed into a shape. The fiber mat is further processed so that the fiber mat retains a desired shape. A heat treatment operation is then performed to convert the fiber mat into a ceramic structure having the desired shape.

The present disclosure relates to a modular fluid modification system having an outer container configured to permit a fluid flow there into at a first location, and to allow the fluid flow to exit the container at a second location spaced apart from the first location. A plurality of fluid contacting elements is housed in the outer container. The fluid contacting elements each form an independent filtering or reactor element. Each fluid contacting element includes a plurality of openings formed in a grid or lattice-like pattern.

The present disclosure relates to a fluid modification system having a container structure and a plurality of independent, ceramic elements. The ceramic elements may be arranged in random orientations and contained in the container structure, thus causing a fluid flow entering the container structure at any given cross-section location to flow over the surfaces of a first subplurality of the ceramic elements, and through the porous walls of a second subplurality of the ceramic elements, before exiting at a second location of the container structure. Each one of the ceramic elements has at least one of a nanofibrous or nanoporous microstructure to enable internal flow both through a wall structure thereof, and over and around the wall structure to affect performance.
