Abstract

A refinishing unit comprises an air handling module and a spray booth, both of which may be used separately. An air handling module suitable for use with a spray booth comprises a housing; fresh air inlet means to said housing; first fan means in said housing receiving fresh air from said fresh air inlet means; a heat generator in said housing; a heat exchanger in said housing, associated with said heat generator and through which air drawn in by said first fan means is passed; an outlet for heated air, heated in said heat exchanger, from said housing; an exhaust gas intake into said housing; second fan means in said housing and connected to said exhaust gas intake and outlet means exhausting gas, drawn in through said exhaust gas intake by said second fan means, to atmosphere. The spray booth comprises a roof structure unit and a floor structure unit, the roof structure unit being supported on the floor structure unit at suitable places by means of support columns.

Claims

1. A refinishing unit for automobiles, comprising:

a portable, free standing weather proof spray booth and a portable, self-contained air handling module connectable to said booth for providing heated, filtered air to said booth and for exhausting the contaminated exhaust air contained within said booth;

said booth comprising a roof unit for supplying air received from said air handling module to the interior of said booth comprising an input chamber in communication with the interior of said booth, a hot air inlet means for connecting said input chamber with the exterior of said booth and replaceable first dry filter means in said input chamber for filtering the air passing through said input chamber into the interior of said booth and for equally dispersing the air flow from said inlet chamber into and about the interior of said booth;

a floor unit having a floor including an air permeable section for allowing the exhaust air to pass therethrough and for supporting an automobile, an under floor chamber means positioned below and in communication with said air permeable section, exhaust air outlet means for connecting said under floor chamber with the exterior of said booth, and secondary replaceable dry filtering means in said under floor chamber for filtering the exhaust air flowing through said air permeable section to said exhaust air outlet means;

four support columns for supporting said roof unit above said floor unit;

wall means having panels and door means for gaining access to said booth, extending from said floor unit to said roof unit and between said columns for enclosing said booth;

said air handling module comprising an enclosed housing, a door providing access to said housing and having a fresh air inlet with replaceable third dry filter means for filtering the fresh air entering said fresh air inlet, a heat generator positioned within said housing, a heat exchanger connected to said heat generator and heated by said heat exchanger, first fan means connected to said fresh air inlet and to said heat exchanger for supplying fresh air to said heat exchanger for heating the air, heated air outlet means connected to said heat exchanger and to the exterior of said housing, exhaust air intake means connected to the exterior of said housing and replaceable fourth filter means for filtering the air passing through said exhaust air intake means, second exhaust air outlet means connected to the exterior of said housing, second fan means connected between said exhaust intake means and said second exhaust outlet means;

said air handling module heated air outlet means and said exhaust air intake means being respectively connected with said hot air inlet means and said exhaust air outlet means of said booth such that a continuous flow of fresh, filtered and heated air is supplied to the interior of said booth from said air handling module and is expelled as exhaust air from said booth to said air handling module and to the atmosphere through said second exhaust air outlet means by said first and said second fan means respectively; and

said air permeable section of said floor unit being positioned with respect to an automobile that is in position for refinishing such that the stream lines of the flow of exhausting air are drawn in around the bottom of the automobile for reducing the turbulence of the exhaust air flow around the body of the automobile.
