In a laboratory hood system having a housing with an access window opening into an interior work chamber for performing laboratory processes, and an air circulation system for creating an air flow from the laboratory environment inwardly through the access window into the work chamber for preventing hazardous materials from escaping into the laboratory environment through the access window, one or more air intake control devices are disposed in a selected location or locations at the access window to overcome any tendency for air turbulence to occur. The air intake control device has an air flow channel extending from an air intake opening to the laboratory environment to an air discharge opening to the work chamber, with a constriction in the channel for causing a venturi-effect increase in air velocity while flowing through the channel to promote non-turbulent air flow entering the work chamber at the selected location or locations.

A local cleaned air supply device includes: a power supply unit, a control unit, and a freely rotatable cleaned air supply unit. The cleaned air supply unit, which includes a fan driven by driving electric power, and of which a height position, a swing angle in a left-right direction, and a tilting angle can be freely adjusted, is configured so that air drawn therein is cleaned by passing through a pre-filter and a main filter and is then discharged toward a front side thereof from an air discharge opening. The cleaned air supply unit also includes a sighting unit that visualizes a range in which high cleanliness is guaranteed in a space on the front side of the cleaned air supply unit. The sighting unit includes a plurality of laser emitting units that output laser beams, to surround the range, toward a front side of the air discharge opening.

Various embodiments are directed to a diffuser headband system. The system may include a diffuser headband formed from an elastic material coupled to a sanitized air generating source that produces sanitized air. The diffuser headband may form a substantially oval shape and include an elastic tube attached to the elastic material. A first portion of the elastic tube may be perforated to include a group of air outlet holes spaced along a surface of the elastic tube. A second portion of the elastic tube may include an inlet that receives the sanitized air from the sanitized air generating source. The air outlet holes receive the sanitized air from the inlet and expel the sanitized air to provide an air shield that encircles a person's body wearing the diffuser headband. The air shield blocks viral aerosol droplets from entering or leaving an airspace occupied by the person wearing the diffuser headband.

Provided is a local clean zone forming apparatus which has an excellent operability and can provide an excellent clean air space without restricting the installation location or the purpose of an operation. In the local clean zone forming apparatus, a pair of push hoods having air blowing surfaces between which an airflow alignment mechanism is formed to form uniform airflows, are disposed so that the uniform airflows discharged from the push hoods are opposite to and collide with each other in a positional relationship wherein the air blowing surfaces are parallel to each other, and the centers of the air blowing surfaces are not directly opposite to each other; and the uniform airflows are obliquely discharged at an angle with respect to the air blowing surfaces.

A safety cabinet includes an operation stage on which an operation is performed, an operation space in which an operator performs the operation, a front panel disposed in front of the operation space, an operation opening connected to the operation space, exhausting means that suctions air from the operation opening and exhausts air in the operation space outside the safety cabinet through air purifying means, and visualizing means that visualizes an air flow in the operation space.
