A fume evacuation system is designed to remove smoke, fumes, and particulate from a metal-working or other application. The system may include a cart-type base unit or may be incorporated into a fixed or semi-fixed installation that uses suction to draw air (e.g., containing smoke, fumes, and particulate) away from the metal-working application. The fume evacuation system includes a hood that creates an arduous flow path and varying velocity profile, which cools and separates any particulate matter in the suctioned air. The arduous flow path may include multiple sharp turns created by an inner deflector component and an inlet tube. The inlet tube may further contain baffles to cool particulates from the suctioned air.

A fume extraction apparatus (1) comprising an extraction pump, and the apparatus comprises a first interface (12) for connection to a process equipment, and a second interface (10) for connection to a system controller, wherein the apparatus comprises an intraconnection (15) to enable signals to be communicated between the first interface and the second interface.

A low-emission hot-in-place asphalt recycling equipment train system is disclosed, which comprises at least three heating units, a milling unit, a centralized hot mix heating unit, a mixing unit, and compatible paving and compacting units. The hot-in-place asphalt recycling equipment train system realizes stepwise uniform heating of pavements, recycling of heat energy, centralized treatment and discharge of fumes, centralized and uniform hot mix heating of materials without causing damage, simultaneous metering and feeding of required materials at multiple points, and on-site mobile batch mixing.

A cleaner system for an MRI magnet room. The system includes a base vacuum and/r steam unit configured to supply vacuum and/or steam, the unit disposed outside the MRI magnet room. A hand-held or portable dispensing unit is substantially free of magnetic material so that it is safe to use inside the magnet room. A tubing system for conveying vacuum and/or steam from the base unit to the handheld unit, the tubing system including a magnet room portion configured for disposition inside the magnet room and free of magnetic material. A communication link is configured to communicate control signals generated by user manipulation of a control panel to the base unit.

A building panel may be installed below a slab in the construction of buildings. The building panel supports the slab and also provides a ventilation layer that may be depressurized to eliminate or reduce infiltration of radon gas into the building. The ventilation layer may comprise channels which provide a two-dimensionally interconnected void. Ventilation panels which include collars for connecting to ventilation systems may be provided. The panels may be installed directly on compacted soil. The building panels may additionally provide sub-slab insulation and/or a capillary break for water drainage. In some embodiments the building panels are formed substantially entirely of thermal insulating material such as rigid polystyrene foam. In an example embodiment the panels are approximately 4 inches thick and have a grid of intersecting channels formed on an underside of the panels.

The disclosure provides a multi-function ductless enclosure apparatus. Its main purpose is to be used as a paint spray booth to capture excess paint, pass it through filters with the use of a fan and then exhaust the ensuing clean air out, back into the room air. This booth is foldable and light weight and can be moved to a different location in minutes. It can also be transformed to serve many other applications with the use of a few accessories thereby saving the end user from having to have several booths (saving counter space) and also saving him from having to spend a lot of money buying many booths for different applications.

The present invention is a method of retrofitting a refrigeration unit, which contains dirty condenser coils, for more efficient operation. The method first comprises cleaning the dirty condenser coils of the refrigeration unit which are contained in an enclosure within such refrigeration unit having an opening. When the coils are in a cleaned condition the enclosure holding those coils is then covered with a non-vented cover that comprises an air-cleaning blower mounted on the outer surface of the cover over an orifice in the cover communicating with the enclosure to supply cleaned air to the enclosure containing the condenser coils.

Disclosed is a system for suctioning braking particles from a friction braking system of a vehicle, the suction system including a negative-pressure source, a suction mouth, a filter, a pneumatic circuit connecting the suction mouth to the negative-pressure source, and a control unit configured to control the negative-pressure source, the suction system also including a pressure sensor for measuring the pressure prevailing in the pneumatic circuit, the control unit controlling the negative-pressure source so that the pressure in the pneumatic circuit reaches or tends to meet a predetermined negative-pressure setpoint, and an associated method.

The present invention provides an UV cleaning device of a glass substrate, comprising a lamp box, an UV lamp positioned above inside the lamp box, a transparent shield positioned under the UV lamp, a humidifier positioned under the transparent shield and a power exhaust device under the transparent shield and opposite to the humidifier; in usage, the glass substrate is conveyed to be inside the lamp box, and UV light generated by the UV lamp irradiates on the glass substrate through the shield to clean the glass substrate and a humidity and an oxygen content inside the lamp box are adjusted with the humidifier to make a surface of the glass substrate adsorb one layer of water molecules. The electrons generated as the UV light cleans can be gradually conducted and led out with water molecules to effectively restrain the accumulation of the electrostatic to reduce the phenomenon of electrostatic damage, and meanwhile, the increase of the oxygen content makes the concentration of the activated oxygen atoms increases along with. Accordingly, the result of cleaning the organic objects with the UV light is promoted.
