FILTER MADE OUT OF A COMPOSITE MATERIAL AND A METHOD OF ITS MANUFACTURE Russian patent published in 2004 - IPC

FIELD: filtration.

SUBSTANCE: the invention is intended for a filtration. The filter made out of a composite material intended for removal of particles kept in a gas has a pipe of at least two previously non connected to each other tiers of a filtering material, that tied together combine an integral unit as a layered structure. The tiers may contain either the thermally linked components, for example - bi-component or single- component polymeric fibers, or the components linked by a binder, for example - fibers of cellulose (in particular - the fluffed up cellulose) or fibers made out of a split film, or mixed fibers charged with static electricity and staple fibers. In addition to use in hoses of filters for the vacuum cleaners the new filtering composite may find application in the systems of warming ventilation and air conditioning, in the air filters of cabins of transport vehicles, in the highly efficient filters (so called NERA) and in filters for "clear" rooms, domestic sleeve filters monitoring of air pollutions, in respirators, in face mask for surgeons, etc. The offered filter has an enlarged dust absorbing capacity, it is a multifunctional and multi-component device.

EFFECT: the filter has increased dust absorbing capacity, it is multifunctional and multi-component device.
