095277000 | Moving filter | 7 |
20110094382 | REDUCED PRESSURE DROP COALESCER - A coalescer includes fibrous media capturing droplets of the dispersed phase, coalescingly growing the droplets into larger drops which further coalesce and grow to form pools that drain, and adapted to reduce pressure drop thereacross by increasing dispersed phase drainage therefrom. | 04-28-2011 |
20120055339 | Gearbox and Self-Renewing Air Filter - An improved gearbox and a method and apparatus for renewing a sheet-type filtering material in a flowing fluid inside a conduit such as for replacement of filters for Heating, Ventilating, and Air Conditioning (HVAC) by applying a force to a force transferring device to ultimately cause movement of a roll of sheet-type filtering material. The method includes attaching one end of the sheet-type filtering material to a gathering roll; stretching the sheet-type filtering material across the conduit and using the force from the force transferring device to rotate the gathering roll, thereby causing a movement of the sheet-type filtering material, in the direction of fluid flow, to the gathering roll thereby advancing the sheet-type filtering material, such that clean filtering material is exposed to the fluid flow. | 03-08-2012 |
20120085237 | PASSIVE FAN FILTRATION SYSTEM (PFFS) - An apparatus that attaches to a ceiling fan and extracts allergens and impurities from the air. The apparatus hangs off the front edge of the ceiling fan paddles [blades] and covers up to | 04-12-2012 |
20130174735 | APPARATUS AND METHOD FOR REMOVING DIRT FROM GAS FLOW - The disclosure relates to a gas permeable wall for preventing dirt present in a gas flow from passing through the gas permeable wall with the gas flow. In order to minimize maintenance, the gas permeable wall is a circumferential wall of a cover, and an outlet from the cover is provided for passing on gas having entered the cover through the circumferential gas permeable wall. A support is provided for attaching the cover rotatably to a device, and a drive unit is provided for rotating the cover. | 07-11-2013 |
20130291727 | HOT GAS FILTRATION SYSTEM - A filtration system particularly suited for removing a particulate material from a hot gas includes a housing, a collection system including at least one collection belt, a cleaning system to clean the collected particulate material from the at least one collection belt, and a removal system for removing the collected particulate material from the housing. | 11-07-2013 |
20140083295 | Filter Assembly with Dynamic Filter Media - A filter assembly for removing particles from air flow across the filter assembly with a frame around a perimeter of the filter assembly, dynamic filter media for removing particles from air flowing from an upstream side of the filter assembly to a downstream side of the filter assembly that passes from a clean filter media storage chamber to a used filter media collection chamber within the frame on a second side of the filter assembly. The dynamic filter media is moved from the output from a turbine shaft modified by a gearbox to drive a set of drive traction rollers. | 03-27-2014 |
20140260983 | GAS FILTRATION SYSTEM - A filtration system for removing a particulate material includes a housing having an air stream flow path communicating between an inlet for incoming polluted air containing particulate material and an air outlet for emitting clean air filtered by removing the particulate material; a filter media collection system provided in the air stream to collect the particulate material, the collection system including at least one spool of filter media; and a filter media cleaning system provided to clean the collected particulate material from the filter media. | 09-18-2014 |
