055383000 | WITH REMOTE FAN OR PUMP AND UNCONFINED FLOW TO SEPARATOR | 10 |
20090031684 | Filtration apparatus - An automatic air filtration apparatus that beneficially controls air circulation in an area to be filtered and removes large amounts of airborne particles and other contaminants from an environment is provided. A hollow frame is formed from screen material having sheet-like filter media disposed across the frame; the filter media is beneficially provided in roll form. The filter media extends off of a supply roll, over the screen frame, and is received on a “take-up” spool. Fans direct opposing streams of air out both lateral ends of the filtration apparatus, thereby creating a suction effect toward the center of the apparatus. Dust particles, contaminants and other debris in an environment are directed back to the filtration apparatus to be collected on the filter material. | 02-05-2009 |
20090133368 | Exhaust conduit and adapter mounting for portable oxygen concentrator - An exhaust conduit and adapter apparatus for mounting to a pair of exhaust outlets mounted oppositely on the base of a portable oxygen concentrator includes an opposed facing pair of substantially unshaped hollow conduits wherein each conduit has an inlet end and an outlet end. The inlet ends are separated by a distance equal to a separation distance between the pair of exhaust outlets. The outlet ends are mounted to each other in fluid communication with a junction having a single outlet. The inlet ends are adapted for mounting to the pair of exhaust outlets so that, when so mounted, hot exhaust from the oxygen concentrator flows through each conduit and out through the junction and the single outlet of the junction. An outflow conduit is mountable to the single outlet of the junction for outflow of the hot exhaust from the single outlet to a remote location, remote from a patient using the oxygen concentrator. | 05-28-2009 |
20090188218 | AIR TREATMENT SYSTEM - An air treatment system includes features for maximizing efficiency and effectiveness. In one embodiment, a sensor air passage utilizes a low pressure region created by the blower to draw air through the passage. In another embodiment, a filter frame includes a plurality of connectors formed integrally with the filter frame. In another embodiment, a screen is positioned adjacent to the blower intake. The screen includes a plurality of angled strands oriented in a particular direction. In another embodiment, a remote control holder is formed integrally with the housing. In another embodiment, a gasket is positioned between the blower and the housing, forming a seal between the blower and the housing. | 07-30-2009 |
20110192124 | DUST COLLECTOR - The dust collector of the present invention includes a main body and a hanging device. The main body includes a shell, a dust container, a sieve element and a suction device. The shell defines a first chamber and a second chamber therein, and the shell is formed with an inlet and an outlet. The inlet communicates with the first chamber, and the outlet communicates with the second chamber. The dust container defines a receiving space communicated with the first chamber, and the dust container stands on a ground surface. The sieve element is disposed on the outlet. The suction device is adapted to draw air from the first chamber into the second chamber. The hanging device is adapted to hang the shell on a wall. As such, the dust collector will be steadily positioned. | 08-11-2011 |
20120000169 | Dust-Filtering Apparatus for a Computer - A novel dust-filtering apparatus for a computer is disclosed. In one embodiment of the invention, the dust-filtering apparatus causes an inflow of air into a filtering chamber by using an air fan which is operatively connected to a DC power source. The inflow of air into the filtering chamber is cleaned and filtered by a first side of a filtering medium which is located on one side of the filtering chamber. A second side of the filtering medium faces a cleaned air evacuation chamber, which has at least an opening to allow the cleaned air to evacuate outwardly from the dust-filtering apparatus. In one embodiment of the invention, the dust-filtering apparatus is designed to be inserted into a drive expansion bay of a desktop computer, with a door on a front side of the dust-filtering apparatus for easy removal of the filtering medium. | 01-05-2012 |
20120151886 | SELF CLEANING FAN ASSEMBLY - This patent pertains to self-cleaning fan assemblies. One implementation includes electronic components positioned in an enclosure. This implementation also includes a fan assembly that is configured to impart rotational force on air to move the air from outside the enclosure to inside the enclosure and around the electronic components. The fan assembly is further configured to separate contaminants from the air based upon differences in density between the contaminants and the air. | 06-21-2012 |
20120192533 | DEVICE FOR FILTERING THE INTAKE AIR OF AN INTERNAL COMBUSTION ENGINE HAVING VENTILATION MEANS - A device for filtering intake air of an internal combustion engine, including at least one filtering element including an inlet for air being treated, a first clean air outlet toward the engine, and a second air outlet toward the outside, and a ventilation mechanism driving the air from the second air outlet. The ventilation mechanism includes a fan wheel driven by a turbine set into motion by a gas flow taken from the engine. | 08-02-2012 |
20130000265 | BLOWER AIR SUCTION DEVICE - A blower air suction device of a motor vehicle air conditioner includes a blower with a vertical arrangement consisting of a blower motor, a blower rotor, and a blower opening, wherein the blower is ensheathed by a blower scroll, and an air inlet housing with a fresh air opening formed in a front wall and with an ambient air opening. The installation of blower is suspended, that is, with the blower rotor under the blower motor, and the air inlet housing is arranged in the process beneath the blower. | 01-03-2013 |
20130031880 | CAR DUMPER DUST CONTROL SYSTEM - An apparatus for rotary dumping of rail cars, including a backside airflow diverter, a backside hood for removing contaminated air from the back side of the pit and at least two baffles on a rotational frame, the baffles each presenting a leading edge that contacts the backside airflow diverter during at least a portion of rotational motion. At least one air intake is positioned to pass through the upper surface of the backside diverter into the backside hood at a location where pressure in the backside hood is maintained at a substantially neutral or negative level even when pressure in the material receiving pit is increased by a down rush of air caused by the exit of the load from the railcar. | 02-07-2013 |
20130118137 | FILTER MOUNTS FOR A PORTABLE FAN AND METHODS FOR MOUNTING A FILTER TO A PORTABLE FAN - A filter frame is removably attachable to a box fan. The filter frame is adapted for receiving a standard HVAC-style filter for removing contaminants from air flow induced by the fan. In this manner, a cost-effective means for filtering a flow of air is provided for residential and commercial settings. The filter frame is adaptable to a variety of standard box fan types of different styles and dimensions. The frame is configured to accommodate standard filters, such as those readily available from retail hardware stores and home centers. | 05-16-2013 |
