An apparatus for producing a clean air curtain to protect a first individual and a second individual from germ transfer between themselves has a housing having an input port and an output port. The apparatus comprises a fan disposed in the housing in communication with the input port to draw air into an input channel through the input port, and in communication with the output port through an output channel to force air from the input channel through the output channel and out the output port. The output channel configured to cause the air forced out the output port to create a laminar flow air curtain. The apparatus has an air filter positioned across the input channel to clean the air drawn through the input port. A method for protecting a first individual and a second individual from germ transfer between themselves with an air curtain.

An air curtain containment system and assembly for data centers forms an air curtain over the server cabinets thereby separating hot air in a hot aisle from cool ambient air. The air curtain containment system includes ducts which include a hot air intake section that receives hot air discharged from servers, which are disposed in server cabinets. The ducts include heat exchangers for cooling the hot air and at least one air curtain discharge section. A housing is coupled to a wall of the ducts, and includes a cooling edge device fan. The cooling edge device fan is disposed along the ducts, and is configured to draw the hot air for cooling through the heat exchangers. An air curtain fan assembly is disposed along the ducts. The air curtain fan assembly expels cold air through the air curtain discharge section, and thereby forms an air curtain over the server cabinets.

An air-based thermal separation system for use proximate rack-mounted IT equipment including: an air circulation system configured to receive input air and generate an output airflow; and an air diffuser system configured to be longitudinally positioned within a hot aisle of a datacenter, the air diffuser system including: an input port for receiving the output airflow, and an essentially-linear discharge port for discharging the output airflow in a generally upward direction to form an essentially-planar discharge airflow.

A gasper module for use in an aircraft. The gasper module including an inlet configured to receive intake air and a first outlet configured to direct a stream of an airflow from the intake air towards a passenger. Also, a second outlet configured to form an air curtain from the intake air between the passenger receiving the direct stream of airflow and an adjacent passenger.

The present disclosure relates to a multi-stage dehumidification system for local area dehumidification of dry room, the system including a main dehumidification part formed to have an inside space that is sealed from outside; a main dehumidifying device for controlling that the relative humidity of the inside of the main dehumidification part is smaller than the relative humidity of the outside of the main dehumidification part; at least one local area dehumidification part that is partitioned within the main dehumidification part, and that has an inside space that is sealed from the main dehumidification part; and a local area dehumidifying device for controlling that the relative humidity of the inside of the local area dehumidification part is smaller than the relative humidity of the inside of the main dehumidification part, wherein the local area dehumidification part includes an opening for entry and exit of objects; a moisture penetration prevention part that protrudes to outside from an edge of the opening; and a first air curtain part that forms a first blocking air flow from one side of an outer opening of the moisture penetration prevention part towards the other side.
