A method for preparing decontamination measures within a room located in a building and used by people includes a planning acquisition step. Therein, a plurality of regions of use within the room are identified, and for each region an expected use intensity is determined based on previously determined parameters. In a subsequent planning implementation step, for each region of use, proceeding from the expected use intensity, a suction means assigned to said region of use and having an associated supply air volume flow is specified. In a method by carrying out the decontamination measures, while the decontamination measures are being carried out, operation of individual suction means is adjusted to an actual use of the assigned region of use by people, and a suction volume flow suctioned by the suction means in question is specified, between a minimum value specified for the suction means in question, and a maximum value.

Disclosed is an air umbrella apparatus including an air suction pipe having an air suction hole in an upper end thereof, a water collection pipe disposed concentrically with the air suction pipe and having an upper end coupled to a water-collection-inducing pipe for guiding rain or snow downward, an exhaust pipe disposed concentrically with the water collection pipe and having an upper end coupled to an exhaust-guiding pipe for guiding air outward, a communication pipe coupled to the air suction pipe, the water collection pipe, and the exhaust pipe for communicating the air suction pipe with the exhaust pipe, and a blower disposed between the exhaust pipe and the water collection pipe for the introduction and exhaust of air. The exhausted air forms an air curtain having a predetermined area above the exhaust-guiding pipe, thereby preventing rain and snow from falling from the exhaust-guiding pipe.

The disclosure relates to an apparatus for reducing the quantity of solid particles in ambient air. A predefined treatment area is delimited at least in part by an enclosure. The enclosure is at least partially non-physical and formed by at least one air curtain that can be produced by an air flow generating device. At least one air filter device, which is connected in terms of flow to the ambient air of the treatment area is designed to filter solid particles directly out of the ambient air of the treatment area.

Disclosed is an airborne contaminant abatement apparatus comprising an air mover having an air mover inlet and an air mover outlet and configured to create an airflow when operating; a filter disposed in fluid communication with the airflow and configured to remove airborne contaminants therefrom; a supply air passage disposed in fluid communication with the air mover outlet and a vent; the vent disposed along at least a portion of a boundary of a plurality of spaces to be occupied, wherein the vent is configured to accelerate the airflow passing therethrough to create an air curtain extending from the boundary; a return air passage configured to receive the airflow at a return port and direct the airflow to the air mover inlet.

A gas curtain device for a load port includes a casing, a holding unit, a gas-permeable plate, and fastening units. The casing defines an inner space and including a flange that defines a gas outlet in spatial communication with the inner space. The holding unit is disposed in the casing, and defines a ventilation opening. The plate is positioned between the holding unit and the inner flange, and has holes. A curtain-forming gas is introduced into the inner space, and sequentially flows through the ventilation opening and the holes to be discharged from the gas outlet to form a gas curtain. The fastening units connects removably the holding unit and the plate to the flange.
