| 20090249956 | AIR FILTRATION MEDIUM WITH IMPROVED DUST LOADING CAPACITY AND IMPROVED RESISTANCE TO HIGH HUMIDITY ENVIRONMENT - A filtration medium is disclosed for use in air filters used in heating, ventilating and air conditioning systems. The medium contains at least one nanofiber layer of fibers having diameters less than 1 μm and at least one upstream layer, the medium having sufficient holding capacity for dust particles that efficiency loss and pressure loss across the medium are minimized during use. | 10-08-2009 |
| 20090266233 | Filter Bag for a Vacuum Cleaner and also Use Thereof - A filter bag for a vacuum cleaner made of a composite material comprising at least three layers, at least two layers which comprise a nonwoven fabric layer and at least one nonwoven fibre layer being connected by a weld. | 10-29-2009 |
| 20100043637 | Filter Assembly and Method - A filter assembly having a filter head having inlet and outlet ports and a top cap having a substantially curved, non-planar flange portion, the non-planar flange sealingly received within the filter head such that the filter head is divided into inlet and outlet partitions. In some embodiments, the flange portion has a generally s-shaped cross-sectional profile. The flange portion incorporating a modified venturi for improved flow of both inlet and outlet streams through the filter assembly. | 02-25-2010 |
| 20100300292 | Smoke And Fume Removal Assembly With Dual Suction Modes - A fan assembly is adjustable between two suction modes by alternating the position of the fan assembly on a flat surface, such as a table top. The fan assembly has two separate suction openings, one smaller than the other, which are selectively sealed by the flat surface. The suction openings are bounded by planar edges of an air guide that protrudes outward from a fan casing of the assembly. In one position, a first suction opening is unobstructed by the flat surface while the second suction opening is either partially obstructed or substantially sealed by the flat surface. In another position, the second suction opening is unobstructed by the flat surface while the first suction opening is substantially sealed by the flat surface. | 12-02-2010 |
| 20110197766 | Building air filtration system - An air filter system and an air filter therefor are provided for use in a building with first and second zones separated by a wall-door system having a wall with a door therein. Weatherstripping is mounted between side and upper edges of the door and a door frame in the wall and between the lower edge of the door and the threshold region of the floor to substantially seal against air flow between the door edges and the door frame and floor when the door is closed. An air flow permitting opening is provided in the wall-door system, sized to permit a controlled amount of airflow between the first and second zones when there is a pre-determined pressure differential between said zones. An air filter is mounted in such opening. | 08-18-2011 |
| 20120174787 | FILTER HAVING FLOW CONTROL FEATURES - A system including, a filter having an exterior surface, wherein the exterior surface contains a three-dimensional surface morphology. | 07-12-2012 |
| 20130192467 | TWO STAGE DUST COLLECTION TRAILER WITH HEPA FILTRATION - A central mobile air collection and treatment platform to establish and maintain a negative air pressure environment in a designated structure. Multiple stage air filtration stations within a central vacuum source combine general dust filtration, collection and disposal with inline multiple particulate HEPA filtration in a high volume self-contained mobile platform configuration for adaptable multi-venue staging. | 08-01-2013 |
| 20140069276 | Process Equipment Contaminant Removal - A method and system remove contaminants from a vapor. In one embodiment, the system includes a contaminant removal system having a vacuum box. The contaminant removal system includes a contaminated vapor from process equipment is introduced to the vacuum box. The contaminated vapor includes steam and hydrocarbons. The vacuum box includes a water removal device. The water removal device removes water from the contaminated vapor to provide water and a reduced water vapor. The contaminated vapor is introduced to the vacuum box below the water removal device. The water and the reduced water vapor are removed from the vacuum box. The water removal device is disposed in the vacuum box at an elevation below an elevation at which the reduced water vapor is removed from the vacuum box. | 03-13-2014 |
| 20140283689 | METHOD AND DEVICE FOR THE DECANTATION OF OIL CONTAINED IN A GAS STREAM - In this process, a gas stream containing the oil to be separated is circulated between an inlet zone and an outlet zone, and a calm vacuum zone is created where the oil is recovered and evacuated, after having been captured. According to the invention, the gas stream is passed in contact with a porous media, one face of which is in contact with the calm vacuum zone. The drops of oil are thus captured by the porous media and sucked through this media to arrive in the calm zone. This process is applicable to decanters of oil at impacters and also to cyclone separators, in particular in the automotive field. | 09-25-2014 |
