摘要： Air filtration systems and methods which intentionally use collected dust to enhance air filtration performance, use air flow rate control to optimally maintain electro-mechanical efficiency and media permeability, use high velocity discharge to "throw"clean air to preferable workplace areas, and use a cylindrical drum design for pleasing appearance and practical features. The systems and methods are particularly applicable as modular filtration units to textile processing environments, but are suitable for more general applications as well.

摘要： A gas borne particle filtering apparatus having a filter medium (13) with inlet and outlet openings (11, 12) in a staggered sawtooth cross-sectional configuration (140, 141) in a casing (10) for the filter medium positioned such that the gas passes along and between the sawteeth on both sides of the filter medium is described. A screened belt or support (14) for the filter medium is described. The apparatus is particularly suited to cleaning heated or cooled air in a confined work space in a factory containing small micron sized particles so that the air can be recycled.
