Appl. No.:

8/415610

Inventors:

David M. Kaiser - Santa Paula CA

International Classification:

B01D 4600

US Classification:

95273

Abstract:

A process, and apparatus for practicing the process, for removing hazardous material collected on a cleanable HEPA filter in a manner which protects operating personnel from exposure to that hazardous material comprising use of a bag composed of high efficiency filter material, the bag being positioned within a vacuum container having a removable lid. The bag has an open top which extends out of the container during the cleaning operation, the container being closed by a removable lid. The system allows the lid to be removed and the bag sealed and extracted from the container without shutting off the vacuum generated flow of air.

Appl. No.:

7/659280

Inventors:

David M. Kaiser - Santa Paula CA

International Classification:

B01D 4604

US Classification:

55 96

Abstract:

Contaminated air is drawn from a relatively enclosed dirty air space and filtered to remove both contaminants and other particulate materials. A main mechanical filter is positioned between the dirty air space and a surrounding environment which is to be protected from contamination. An exhaust fan is positioned on the output side of the main filter, to create a partial vacuum within the dirty air space. An irradiation device is positioned on the output side of the main filter. A secondary vacuum system is utilized to create a secondary vacuum that is substantially stronger than the partial vacuum applied to the main filter, and the secondary vacuum is applied to successive selected portions of the air input side of the main filter for creating a reverse air flow to clean contaminants and other particulate materials which are being continuously deposited there. Within the secondary vacuum system air is circulated through at least one filter element that is located remotely to the dirty air space, and the thus filtered air is then dumped back into the air input side of the main filter. Accumulated particulate material is removed from the remote filter from time to time, without entering the dirty air space itself.

Appl. No.:

8/016756

Inventors:

David M. Kaiser - Santa Paula CA

International Classification:

B01D 2917
B01D 2970

US Classification:

55283

Abstract:

A self-cleaning air filter is formed by placing a flexible filter bag in an upside-down position with its open end firmly supported. Air to be cleaned is pulled upwardly through the bag. When the air stream is shut off, the bag collapses, discharging accumulated particulate material into the space beneath it.

Appl. No.:

7/911279

Inventors:

David M. Kaiser - Santa Paula CA

International Classification:

B01D 4604

US Classification:

55294

Abstract:

An air flow system for removing airborne particulate material includes a bank of filters through which air is moved in one direction, thus depositing particulate material on an air input side of the filters. A vacuum head associated with a secondary vacuum system is intermittently applied in a reciprocating movement to selected portions of the air input side of the filters for cleaning them, while the remaining portions of the filters continue to operate in the normal manner without interruption. Both the filters and the vacuum head are provided with integrally formed interengaging guide means which facilitate this operation.
