摘要： A fume hood control system includes a fume food. The fume hood includes a first baffle, a sash and a hood enclosure positioned within an environment. The hood enclosure includes a plurality of sidewalls forming a work chamber, a first aperture configured to permit an airflow between the environment and the work chamber, and a second aperture configured to permit the airflow between the work chamber. The sash is configured to at least partially cover the first aperture. The first baffle is configured to direct a path of the airflow within the work chamber. The first baffle is transitionable between a first number of positions. The fume hood control system includes a controller configured to determine, via a sash sensor, a current position of the sash. The controller is further configured to determine, via a baffle position sensor, a current position of the first baffle. The controller is further configured to control the operation of the first baffle to transition between the current position of the first baffle and an updated position of the first baffle in response to the current position of the sash, the current position of the first baffle, and one or more pressure measurements.

摘要： A cleaning booth has a handheld blaster, which emits a pulsed electromagnetic wave that is produced by a wave source. A fiber-optic cable feeds the wave from the source to the blaster. An operator can aim the blaster toward a part that rests on a movable table in the booth. When the operator actuates the wave source, a radiation beam from the blaster ablates anti-reflective coating residue from the part. The cleaning operation can be performed in a same room as the anti-reflective coating process equipment.

摘要： Sample contamination is suppressed by strengthening the air barrier of a work opening portion. A safety cabinet includes: a work room; a front surface door covering a part of a front opening portion of the work room; and a work opening portion on a lower side of the front surface door allowing a worker to work with his or her hand in. An intake port suctions air in the work room and outside air through the work opening portion on a front surface side of a workbench in a lower portion of the work room. A straightening plate drawing an air flow and a linear light source are provided on the work room side of the front surface door and above a front portion of the work room.

摘要： Embodiments of the invention provide an intake apparatus for a local ventilation system. According to at least one embodiment, the intake apparatus includes a connection opening, a hood configured to connect an intake opening larger than the connection opening, an intake duct coupled to the hood while communicating with the connection opening, and an intake fan which is installed at a peripheral portion of the intake opening so as to generate an intake air current in the direction of the connection opening. According to at least one embodiment, the intake fan is provided multiple in number in the circumference direction of the intake opening to generate an intake air current flowing from the intake opening to the connection opening, and a mixed flow prevention body is formed protruding in a partition shape from the intake opening to the intake duct along the inner side of a corner of the hood, and a plurality of lattice exhaust guide flow passages are disposed on straight lines and are isolated from each other, and an air current alignment lattice is installed in the inner space of the intake duct for the lattice exhaust guide flow passage to be disposed in the longitudinal direction of the intake duct.

摘要： Disclosed is a work booth safety system for an automotive body repair shop including a work booth with a ventilation system for evacuation of polluted air and an entrance closed or opened by a door or drape. The work booth is configurable into three different work modes: 1) For preparative dent repair, the entrance is kept open and electrical sockets and compressed air supply is deactivated. Ventilation air flow is mainly directed in a horizontal direction and evacuated through a wall ventilation outlet duct. 2) For spray application of a body sanding foundation, the entrance is closed and electrical sockets are deactivated, the compressed air supply is activated, and the ventilation air flow matches that of work mode 1. 3) For welding, the entrance is closed and electrical sockets are activated. The compressed air supply is deactivated and the ventilation air flows vertically upward through a roof ventilation outlet duct.
