An airborne pathogen extraction system that provides for continuous airborne pathogen particle extraction from a specifically targeted area in a room or a specifically targeted area proximate to a user. The pathogenic particles are filtered and/or disinfected before the air is returned proximate to the originating location, or are directed an area away from the user(s). The airborne pathogen extraction systems and methods lower the chances of contagion or infection from airborne pathogens, such as viruses.

An air frame system includes a frame body defining one or more openings and a plurality of air passages along an inner periphery of the one or more openings. The air frame system further includes a light assembly removably coupled to the frame body outside an outer periphery of the one or more openings.

A safety cabinet includes a work space where work is performed; a front panel disposed in a front surface of the work space; and an air cleaner that cleans air to be supplied to the work space. An imaging device is disposed on one side surface side of side surfaces of the work space, and a connection opening is disposed on the other side surface side facing one side surface.

A sash system includes a sash, a counter-weight coupled to the sash by a coupling member, a locking mechanism coupled to at least one of the sash and the coupling member, and a controller coupled to the locking mechanism. The locking mechanism is transitionable between an open configuration where the locking mechanism does not inhibit movement of at least one of the sash and the coupling member, and a locked configuration where the locking mechanism inhibits movement of the at least one of the sash and the coupling member. The controller is configured to control operation of the locking mechanism to selectively transition between the open configuration and the locked configuration based on a condition of the sash. The sash and the counter-weight are configured such that when the locking mechanism is in the open configuration, the sash lowers due to gravity.

A testing apparatus including a base and a preheating unit arranged on the base is provided. The preheating unit includes a gas generator, a blocking mechanism and a heating device. The gas generator is configured to discharge air toward the base to form an air wall. The blocking mechanism is located above the air wall and forms a heat preservation space with the air wall. The heating device is arranged in the heat preservation space.

A system for air decontamination in a three-dimensional space described herein includes an air inlet for drawing in air, an air outlet for administering filtered air, and a filter device for filtering air prior to administration through the air outlet, the system is configured to draw air in a substantially vertical laminar flow from a ground of the space to the air inlet. A filter device for filtering ultrafine particles from a gas described herein includes a first filter medium for absorbing polar liquids but not ultrafine particles; in fluid communication with a second filter medium for absorbing ultrafine particles; and a gas outlet, the first filter medium is configured to allow vaporization of the absorbed polar liquids; the device is configured to guide the gas from the first to the second filter medium and through the second filter medium; and the second filter medium forms the gas outlet.

A portable packing table having a temperature-controlled work area is provided. The table defines a chamber for dry ice or like substance and has a surface on which an open-topped upright chimney is mounted for receiving a flow of conditioned air from the chamber and for defining a temperature-controlled work area therein. A fan unit is connected to the table for forcing a flow of ambient air into the chamber, and a control unit is connected to the fan unit for automatically controlling operation of the fan unit to maintain air temperature within the chimney within a set temperature range.
