Abstract
Abstract An apparatus for the recovery of contaminated air and water from a flow system. The apparatus provides a high efficient compartmentized stacked design embodying removable filters that first effect a moisture separation and then air borne particle filtering, with such functions separated by a fluid collection tank. The apparatus provides structure for ready removal of the filters and collected fluid with minimum down time so as not to interrupt the recovery process.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
162 words
A mobile contaminated air/water recovery apparatus adapted to be used with a vacuum powered recovery system, comprising, (a) a cabinet having an open top and a partially opened side wall, (b) an interior divider forming compartments within said cabinet, (c) a fluid collection tank closing the bottom of said cabinet with said compartments arranged in side by side relation and stacked upon said tank, (d) a top closure for said cabinet divided into separate sections one for each of said compartments so as to provide access and egress from respective compartments, (e) horizontally disposed filter means in each of said compartments, whereby contaminated air downwardly flows through one filter and upwardly flows through a filter downstream of said one filter, (f) means removably supporting said filter means in each of said compartments whereby said filter means are accessible through said partially opened side wall of said cabinet, and (g) means for closing said partially open side wall and each of said compartments.
Claim 2
Dependent Claim
162 words
A mobile contaminated air/water recovery apparatus adapted to be used with a vacuum powered recovery system, comprising, (a) a cabinet having an open top and a partially opened side wall, (b) an interior divider forming compartments within said cabinet, (c) a fluid collection tank closing the bottom of said cabinet with said compartments arranged in side by side relation and stacked upon said tank, (d) a top closure for said cabinet divided into separate sections one for each of said compartments so as to provide access and egress from respective compartments, (e) horizontally disposed filter means in each of said compartments, whereby contaminated air downwardly flows through one filter and upwardly flows through a filter downstream of said one filter, (f) means removably supporting said filter means in each of said compartments whereby said filter means are accessible through said partially opened side wall of said cabinet, and (g) means for closing said partially open side wall and each of said compartments.
Claim 3
Dependent Claim
44 words
A contaminated air/water recovery apparatus as defined by claim 1 wherein said means for closing said partially opened side wall of said compartment comprises a pair of removable doors adapted to fit upon opening defining flanges provided by said side wall of said cabinet.
Claim 4
Dependent Claim
58 words
A contaminated air/water recovery apparatus as defined by claim 1 wherein said filter means in each of said compartments comprise a first moisture separator and a second air filter, said moisture separator positioned in the gravity flow side of one of said compartments, with said air filter in the air flow side of said other of said compartments.
Claim 5
Dependent Claim
44 words
A contaminated air/water recovery apparatus as defined by claim 3 wherein said means for closing said partially opened side wall of said compartment comprises a pair of removable doors adapted to fit upon opening defining flanges provided by said side wall of said cabinet.
Claim 6
Dependent Claim
48 words
A contaminated air/water recovery apparatus as defined by claim 4 wherein said means removably supporting said filter means in each of said compartments include rails on opposite internal side wall surfaces of each of said compartments for removably supporting said filter means within said compartments of said cabinet.
Claim 7
Dependent Claim
48 words
A contaminated air/water recovery apparatus as defined by claim 1 wherein said means removably supporting said filter means in each of said compartments include rails on opposite internal side wall surfaces of each of said compartments for removably supporting said filter means within said compartments of said cabinet.
Claim 8
Dependent Claim
44 words
A contaminated air/water recovery apparatus as defined by claim 6 wherein said means for closing said partially opened side wall of said compartment comprises a pair of removable doors adapted to fit upon opening defining flanges provided by said side wall of said cabinet.
Claim 9
Dependent Claim
58 words
A contaminated air/water recovery apparatus as defined by claim 6 wherein said filter means in each of said compartments comprise a first moisture separator and a second air filter, said moisture separator positioned in the gravity flow side of one of said compartments, with said air filter in the air flow side of said other of said compartments.
