    Abstract: A local air cleaning apparatus (1) is provided with a push hood (2) having an air flow opening face (23) for blowing out a cleaned uniform air flow and a guide (3) provided on a side of the push hood (2) having the air flow opening face (23), the guide (3) extending from the side thereof having the air flow opening face (23) toward a downstream side of the uniform air flow to form an opening face (31) at a downstream end portion thereof. The push hood (2) is arranged such that the uniform air flow blown out from the air flow opening face (23) passes through the inside of the guide (3) and then collides with an air collision face (W) on a downstream side of the opening face (31). The opening face (31) of the guide (3) is spaced apart from and opposed to the air collision face (W) to form an open region between the opening face (3) and the air collision face (W).

  • Patent number: 8961642
    Abstract: A filter device for separating paint overspray from a raw gas flow containing overspray particles is provided, including at least one filter element, to which at least a part of the raw gas flow is feedable, and a clean gas chamber, to which the raw gas flow filtered by the filter element is feedable as a clean gas flow. In the event of a filter rupture at at least one filter element of the filter device, contamination of the clean gas side of the filter device and regions downstream of the filter device of a painting installation containing the filter device is kept as low as possible through use of at least one safety filter arranged downstream of the at least one filter element and associated with the clean gas chamber such that at least part of the clean gas flow is filterable in the event of a filter rupture.

  • Patent number: 8961638
    Abstract: A dust-collecting apparatus is described that includes a lift-off door assembly that provides access to the interior of the dust-collecting apparatus while minimizing the adverse effects on the normal operation of the apparatus by maintaining a proper seal between the interior and the exterior of the apparatus. In particular, the lift-off door assembly includes a top plate, a door frame, and a bottom plate. The top plate is secured to the door frame. Lift clips are provided about a perimeter of the bottom plate and are secured to the bottom plate. Lifting ends of the lift clips are positioned over an outer portion of the door frame, such that when a lifting force is applied to the top plate, the top plate, door frame, and bottom plate are lifted together via the lift clips to move the lift-off door assembly from the closed position to the open position.

  • Publication number: 20150033683
    Abstract: A fume hood, which comprises a plurality of peripheral inclined drainage channels for receiving condensed grease that is gravitationally delivered thereto from a region of the fume hood thereabove. One of the drainage channels continuously extends into an adjacent drainage channel therebelow to provide a single passageway that delivers the received grease to a single grease collection hole. Each of the drainage channels comprises a surface along which the received grease flows and which slightly extends inwardly into a hood interior from a bottom edge of a corresponding wall of the hood, and a border element which extends vertically above an inward edge of the drainage channel surface to a sufficient height which prevents the flowing grease from spilling into the hood interior.

  • Patent number: 8940065
    Abstract: A ductless laboratory hood apparatus includes a housing defining an interior work chamber, a filtration chamber, an access window opening into the work chamber from an ambient laboratory environment, and an exhaust outlet opening from the filtration chamber into the laboratory environment, a filter system disposed between the work and filtration chambers, and an air circulation system for creating and directing an airstream to flow from the laboratory environment through the access window, the work chamber, the filter system, the filtration chamber, and the exhaust outlet to return into the laboratory environment. The filter system has both a main filter whose constituent material is highly efficient but is also degradable if exposed directly to laboratory processes, and an attenuation filter disposed between the work chamber and the main filter to intercept and attenuate laboratory processes that potentially degrade the main filter, thereby preventing degradation of the main filter.

  • Patent number: 8936671
    Abstract: An aircraft has a ventilation system that employs a plurality of nozzles positioned in a cavity between a sidewall of the aircraft cabin and a section of the aircraft fuselage. The nozzles receive a supply of ventilation air and direct jets of air from the nozzles, through the cavity and into the aircraft cabin. The jets of air produced by the nozzles create low-pressure areas in the cavity. At least one return air opening in the cabin sidewall communicates the low-pressure areas with the cabin interior, whereby the low pressure areas draw air from the cabin interior into the cavity where the drawn air is entrained with the jets of air produced by the nozzles. Devices inside the cavity remove suspended impurities from the air drawn into the cavity. In this manner, the ventilation system filters or sanitizes the air drawn through the system.
