International Classification:

B01D 4702
B01D 5000

US Classification:

55227

Abstract:

A water washed air scrubber in which the contaminated air is first directed toward the surface of a bath of water and cleaning agent at relatively high velocity to create adequate turbulence to achieve a scrubbing action to remove a majority of the contaminate, and thereafter passed through a filter to remove any remaining liquid and/or contaminate.

Appl. No.:

7/475246

Inventors:

Arnold S. Kaufman - Studio City CA

Assignee:

Renco Systems, Inc. - Glendale CA

International Classification:

F24C 1520

US Classification:

126299R

Abstract:

A roof mountable kitchen grease exhaust blower is constructed with hinged housing elements which can be raised for easy service access to all parts of the unit. Redundant blower drive motors are provided either of which can be easily engaged to the blower wheel in the event of failure of the other. A blower wheel drive belt is equally engageable to either drive motor and changeover from one to the other is easily and quickly made by minimally skilled personnel. The newly engaged drive motor is enabled by a power select switch at the blower control panel.

Assignee:

National Food Service Equipment Fabricators, Inc. - Glendale CA

International Classification:

F24C 1520

US Classification:

Appl. No.:

5/807917

Inventors:

Arnold S. Kaufman - Studio City CA
Robert L. Anderson - Reseda CA

Assignee:

National Food Service Equipment Fabricators, Inc. - Glendale CA

International Classification:

F21C 1508
F23J 1100

US Classification:

126299D

Abstract:

An air ventilation and washing system for extracting noxious or other impure air, such as is present above the cooking surface of a stove having automatically activated electrical and mechanical fire control apparatus selectively responsive to changes in temperature is disclosed. The air ventilation system has a hood structure providing a make-up air distribution plenum through which air is distributed and pressurized for equal distribution of make-up air along the length of the hood structure. A vortex baffle is provided in the hood between a make-up air cavity and an exhaust cavity to cause efficient mixing of room air and make-up air from the exterior, while protecting personnel from exposure to the exterior make-up air, and a vortex chamber causes the mixing of the make-up air and room air with contaminated air from the stove.

Appl. No.:

7/475223

Inventors:

Arnold S. Kaufman - Studio City CA

Assignee:

Renco Systems, Inc. - Glendale CA

International Classification:

F24C 1520

US Classification:

126299D

Abstract:

A roof mountable kitchen grease exhaust blower is constructed with hinged housing elements which can be raised for easy service access to all parts of the unit. A container collects grease draining from a discharge scoop and has a flotation separator for harmlessly eliminating water while retaining grease. Grease containment edges on the discharge scoop contain and collect grease being carried by the exhaust air stream along inner scoop surfaces. The discharge scoop has a curved bottom wall to encourage gravity flow of grease collecting on the scoop surfaces towards a drain opening.

Appl. No.:

6/628290

Inventors:

Arnold S. Kaufman - Studio City CA

Assignee:

National Air Systems, Inc. - Glendale CA

International Classification:

F21C 1508
F23J 1100

US Classification:

126299D

Abstract:

Improved air flow characteristics are obtained in a ventilating hood of the make-up type used over cooking surfaces by providing an air distribution panel comprising a panel frame to which is mounted a duct which serves to partition air flow between a first path exterior to the duct and a second path through said duct. A first air flow restricting screen is mounted to the panel frame externally of said duct for restricting air flow through the first flow path, and a second air flow restricting screen is mounted within said duct for restricting the air flow therethrough. The duct includes an internal wall surface which is angled towards the first flow path so as to direct air flow through the duct into merger with air flowing through the first flow path.
