In various example embodiments, a fume hood apparatus is disclosed. The fume hood apparatus comprises an enclosure defining a workspace with a windable transparent sash at the face of the hood that is wound around a roller shaft when in a storage state. The apparatus further comprises an air filter assembly, sash position sensors, exhaust and supply air ducting with fans and dampers controlled by a microprocessor, along with a user interface that allows monitoring and control of the various functions of the apparatus.

A workpiece positioning system integrated with a fume extraction device is provided. The system comprises a movable work surface assembly and a manifold. The work surface assembly includes a plurality of work surfaces and a plurality of ventilation ports. Each of the plurality of ventilation ports is disposed on each of the plurality of work surfaces to ventilate the corresponding work zone. The manifold is disposed below the work surface assembly and coupled to a duct system through which fumes produced during welding or cutting are to be transported to the fume extraction device. When a workpiece placed on a work surface is positioned for welding or cutting, the manifold is aligned and in fluid communication with the ventilation port corresponding to the work surface.

A fume hood comprising: a hood a work chamber, and a front wall formed with an opening toward an indoor environment; an air supply system, and an air exhaust system to discharge air that enters the work chamber through a front opening and enters the work chamber through the air supply system, out from the work chamber; the air supply system provided with at least one air supply outlet in an upper portion and a lower portion of the hood, and the air supply outlet supplying air towards the work chamber. The fume hood can reduce energy consumption of air conditioning and suppress overflowing of harmful substances in the work chamber, with a low installation cost and a high consistency of product quality.

An open fume capture and exhaust work station for a laboratory classroom having an air exhaust system that provides unobstructed sight lines for students at the station of the other students and of a classroom instructor. The work station includes an upper table surface providing a plurality of individual work surfaces, a fume extractor extending upwardly from a middle portion of the table surface to an elevation below the student sight lines, a pair of elongated air outlet openings adjacent to opposed sides of the table for directing fan generated opposed airflows to the extractor which defines opposed upstanding air inlet faces and communicates those faces with the air exhaust system creating a pressure drop within the extractor that captures the opposed inwardly airflows and pull the airflows over the individual work surfaces and into said extractor, capturing and removing emissions from spills and experiments on those work surfaces.

A crossflow table having a housing and a work surface. The housing includes an air intake path in fluid communication with the work surface. The air intake path has an intake entrance and intake exit. A filter and blower unit are positioned adjacent the intake exit. An air exhaust path has an exhaust entrance and exhaust exit. The exhaust entrance is adjacent the filter and blower unit. The air intake path and air exhaust path generally extend parallel to one another. The filter and blower unit draw air into the air intake path at the intake entrance and pull the air though the air intake path where the air exhausts into the filter and blower unit at the intake exit. The blower unit then pushes the air into the air exhaust path at the exhaust entrance and forces the air through the air exhaust path and out the exhaust exit. Due to the intake and exhaust paths being generally parallel to one another, the crossflow table is very compact in overall dimensions.

A board shaping support and tool chest allows for the storage, transportation, and mounting of wood shaping tools. The board shaping support and tool chest includes an elongated block with a first storage compartment and a second storage compartment to house tools and materials. A first guide lid and a second guide lid retain the contents of the first storage compartment and the second storage compartment during transportation, as well as support a board to be cut or shaped. A shaping tool, such as a miter saw, drop saw, circular saw or router, is positioned between the first guide lid and the second guide lid during implementation. The board shaping support and tool chest further includes a first guide support and a second guide support to align the board to the fence of a miter or drop saw and prevent the board from kicking out from the saw blade rotation.

A housing assembly for selectively receiving a part includes a platform and a pad fixed to the platform. The pad has a frictional surface for maintaining a position of the part relative to the pad when the part is disposed on the frictional surface. The housing assembly includes a door apparatus coupled to the platform. The door apparatus surrounds the pad. The door apparatus is movable to an open position in which the frictional surface of the pad is exposed outside of the door apparatus for receiving the part and a closed position in which the frictional surface of the pad is concealed inside of the door apparatus. A method of removing particles from a frictional surface of a pad before performing a manufacturing process has a door apparatus disposed in a closed position to present a chamber that encloses the pad.
