Abstract

An air filter for a clean room or other air-conditioned chamber prevents leakage of unfiltered air into the clean room. Unfiltered air passes into the housing via spigot 1. Air filtered by filter 4 passes through hole 7 into the clean room. Vent hole 2 vents any air outside the filter 4 to an area outside the clean room. The housing has a top plate 3, which presses on the top of the filter frame 4, sides 5 and a bottom plate 6. By detaching the top or bottom plate, the filter can be changed from either side of the housing.

Description

2353959 Patent Application of Albert Robert Lowes, for AIR FILTER HOUSING
INVENTORS NUMBER 92
BACKGROUND-FIELD OF INVENTION
This invention relates to a method making, a filter housing, that where positive -pressure exists within the chamber or room, no unfiltered air is 'Permitted to enter.
BACKGROUND-DESCRIPTION OF PRIOR ART
The disadvantages of Prior art is that irj exceptional. circumstances leakage of unfiltered air into the clean room or chamber can occur, even when super seals are used, and expensive high -precision filter holders are utilized leaks can occur.
OBJECTS AND ADVANTAGES Accordingly, beside the obJects and advantages of reducing the Possibility of a leak of unfiltered air into the chamber or room, the filter holder can be manufactured with moderate cost, also the filter can be changed from the top or bottom SUMMARY OF INVENTION WITH OBJECTS
A general obJect of the invention is to' provide a filter housing where a high degree of confidence in its functionality can be 2 provided, and at same time be inexpensive to build.
DESCRIPTION OF THE DRAWING
Figure one is a schematic drawing incorporating the principles of the present invention.
REFERENCE NUMERALS IN DRAWING I spigot.
2 Vent Hole, 3 Top plate.
4 Filter Frame.
Housing Side.
6 Bottom Plate.
7 Air Hole.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Figure one, shows a filter and housing acordiniz, to the invention, The spigot 1, allows connection to a means to flow air into the housing, vent hole 2, vents any air outside of filter 4, to an area outside of the conditioned chamber or room, top -plate 3, Presses on the top of the filter frame 4, sides 5, connect to top -plate 3, and bottom Plate 6, hole 7, allows filtered air to Pass out of the filter housing into the conditioned room or chamber, various other embodiments will be apparent to those skilled in the art, and could be made without departing from the spirit and scope of the invention as defined by claims that follow.
