Provided is a clean booth in an assembled state, including: a frame; a wall portion that is provided on the frame and forms an internal space; a first unit that is provided on the wall portion and includes a first fan that supplies air to the internal space via a first filter; and a second unit that is provided on the wall portion and includes a second fan that exhausts the air in the internal space.

Provided is an air cleaner that can take a large amount of air in a large space into a dust collector with good efficiency while being lightweight and having easy maintenance. An air cleaner is provided with a drone and a dust collector. The drone has a main body unit and propellers attached to the tips of frames. The dust collector has electric discharge electrodes and a dust collection electrode. The electric discharge electrodes are connected to a booster unit within a central chamber. The booster unit is electrically connected to a control unit in the main body unit. Electric discharge is formed between the dust collection electrode and the electric discharge electrodes, and dust particles in the air are charged and collected by the dust collection electrode.

An air-circulation table for providing filtered air to its users is disclosed, the table including a table top with a working surface and a table base provided below the table top. The table base defines an interior space for housing an air filtration unit. The table top includes one or more air outlet nozzles that are disposed at the working surface to direct filtered air from the air filtration unit toward the users. The table top further includes one or more air inlet vents that are disposed at the working surface to receive return air to be filtered by the air filtration unit. At least one of the one or more air inlet vents are provided closer to an edge region of the table than the one or more air outlet nozzles.

The present disclosure relates to an air conditioning system and method for disinfection of a public facility. More specifically, the present disclosure relates to an air conditioning system and method for disinfection of a public facility capable of sterilizing or inactivating bio-aerosols existing in interior space by using the air conditioning equipment installed in the public facility structures.

An air conditioner includes: an air blower configured to take air from an inlet, and to blow the air from an outlet; a filter configured to purify the air; a first chamber and a second chamber taking the air purified by the filter; a humidification filter provided in the second chamber, and humidifying the air taken into the second chamber; and a divider opening and closing an opening that provides communication between the first chamber and the second chamber, and adjusting a volume of the air taken from the first chamber into the second chamber. The air taken from the first chamber into the second chamber and/or the air taken into the second chamber is blown from the outlet.

Provided is an air conditioning system that maintains a room pressure in a clean room at high accuracy while having a simple configuration. An air conditioning system includes: a fan filter unit including a supply air fan to supply air to a preparation room from a chamber including space above a ceiling of the preparation room; a fan filter unit including a supply air fan to supply the air to the preparation room from the chamber; and a fan filter unit including a return air fan to return the air from the preparation room through the chamber and to exhaust the air from the preparation room, and further includes: a pressure sensor provided in the preparation room; and a control unit to control a return air fan based on a value detected by the pressure sensor.

The disclosed system comprises a primary air curtain system and one or more optional apparel and/or accessory air curtain subsystem components. The primary system and subsystem(s) are configured to create a directionally controlled air curtain effect that repulses, repels, redirects, neutralizes, and/or disperses airborne infectious pathogens, carcinogens, chemicals, and other contaminants away from the body of a user or a surface susceptible to foreign contamination within a protected enclosure.

A grossing station comprising a table and an overhead hood connected to the table. The grossing station further comprising a plurality of interchangeable plates arranged in a trough of the table and a lift system connected to the table. The grossing station also comprises a touch screen controller arranged on a surface of the station, wherein the touch screen controller is in communication with at least one manual toggle switch for overriding an electronic control and monitoring system if a system failure occurs within the grossing station.

Provided is a method for decomposing nicotine in a simple way. A method for decomposing nicotine, according to the present invention, includes a step(a) of irradiating ultraviolet light with a main peak wavelength of 200 nm to 230 nm in a target room allowing smoking to decompose the nicotine.
