A virus elimination assembly for sterilizing air includes a base that is hollow. An intake vent is pivotally coupled to the base to direct air into the base. A canister is coupled to the base and the canister is in fluid communication with an interior of the base. A filter tray is slidably positioned in the canister and a filter is integrated to pass air therethrough. A blower tray is slidably positioned in the canister and a blower is integrated therein to blow air when the blower is turned on. A light tray is slidably positioned in the canister and a light emitter is integrated therein to eliminate viruses and bacteria. An exhaust vent is pivotally integrated into the canister to direct the air that has been sanitized by the light emitter out of the exhaust vent.

The present application proposes an air cleaner including a blower configured to inhale air from an outside, filter the inhaled air, and discharge the filtered air; a flow adjusting device disposed above the blower, wherein the flow adjusting device is configured to inhale the air discharged from the blower, adjust a discharge direction of the inhaled air and discharge the air therefrom to the outside in a adjusted direction; and a guide member having one end passing through an upper surface of the blower and received in the blower, and the other end connected to the flow adjusting device. The guide member is configured to retract into an interior of the blower or extend from the upper surface of the blower to induce position change of the flow adjusting device. The angle defined between the upper surface of the flow adjusting device and the upper surface of the blower increases or decreases primarily based on an extent to which the guide member extends from the blower.

In a method for operating a surface treatment installation, overspray produced in a coating booth is taken up by an air stream and carried to one or more one-way filter modules, in which overspray is separated. Once a limit loading with overspray is reached, a one-way filter module is exchanged for an empty one-way filter module. Depending on the nature and characteristics of the overspray, the one or more one-way filter module(s) may be chosen from a set of different one-way filter modules. A set of filter modules for use in a surface treatment installation is provided having various filter modules formed as exchangeable one-way structural units with a module housing and a filter unit. The module housings of the various filter modules have the same-connection module inlets and the same-connection module outlets and at least the filter units of two different filter modules are formed differently.

A filter assembly including a plurality of filter modules, wherein each filter module in the plurality of filter modules includes a frame, a filtration element coupled within the frame, and at least one mating feature. The at least one mating feature of each filter module is configured for selective engagement with the at least one mating feature of another filter module such that the plurality of filter modules are coupled together in a serial arrangement.

In order to provide a filter system for separating off contaminants from a stream of untreated gas that contains contaminants that is of simple construction and is operable efficiently, it is proposed that the filter system should include the following: a base construction through which the stream of untreated gas is guidable and which includes at least one filter module receptacle for receiving at least one filter module, and at least one filter module which is selectively arrangeable on and/or in the at least one filter module receptacle and/or removable therefrom, wherein the at least one filter module includes a plurality of filter element receptacles for receiving a plurality of mutually independent filter elements.

A housing main part of a filter housing has an element receiving space and an adapter chamber. A filter element is inserted into or removed from the element receiving space through a lateral mounting opening. A pre-separator module and the filter element are arranged behind each other along the main flow axis of the fluid to separate an outlet from an inlet of the filter housing. The adapter chamber accommodates the pre-separator module and/or the filter element. The adapter chamber is arranged at an axial end face of the housing main part and is open axially toward the element receiving space and, axially opposed thereto, toward the environment. The mounting opening is surrounded by a cover receiving rim that extends across the adapter chamber. A part of a connecting device within the housing main part is used to attach the pre-separator module to the housing main part.

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.

A stackable air treatment device is provided and includes a base, a cover, a plurality of air treatment modules modularly stackable between the base and the cover in groups of one or more to form a stack with the base and the cover and a blower configured to move air from an exterior of the stack into the stack and out through the cover. Each air treatment module in the stack is configured to purify, clean, and/or condition the air moved by the blower.

The present disclosure generally relates to an air filtration system, an air filtration device, and an air filtration module for removing ultra-fine particles (UFPs), pathogens (e.g., viruses, bacteria, etc.), volatile organic compounds (VOCs), oxides or odors. The systems, devices, and filter modules of the disclosure perform at enhanced filter and power efficiencies. An air filtration system is provides that includes a docking base for receiving a removable, portable air filtration device in fluid communication with the docking base. In certain embodiments, the air filtration system further includes the removable, portable air filtration device. The portable air filtration device may optionally include an air filtration module.

A general-purpose air sterilizing system destroys activation of air-borne pathogens, designed with different embodiments. The methods used to build the apparatus allows destroying airborne pathogens like bacteria, mold, mildew, allergens and deactivates viruses such as SARS CoV-2. The apparatus supports air circulation system that contains filter which comprising array of Ultraviolet (UV) Light Emitting Diode (LEDs) of 262-nm wavelength, AKA UVC, are used.
