Portable Ventilation Unit
First Claim
1. A portable and reusable ventilation unit that can be sealed to an opening in a large temporary overspray enclosure employed during painting for containment of paint overspray, including the painting of large yachts and marine vessels, said ventilation unit comprising:
- a housing having a front end, an open back end, and two opposing side walls extending between said front end and said open back end, a pre-filter area associated with said open back end, an exhaust area associated with said front end and having at least one exhaust opening, and an intake area located between said pre-filter area and said exhaust area;
at least one door movable from a closed position sealing said open back end in said housing during periods of non-use to at least one open position that provides unobstructed airflow into said pre-filter area;
primary filter material located in said pre-filter area;
at least two fans located in said intake area;
a controller for each of said fans; and
final discharge filter material covering said at least one exhaust opening, so that when said open back end of said housing is connected to a large temporary overspray enclosure employed during painting, operation of said fans in said housing draws air from said large temporary overspray enclosure through said primary filter material in said pre-filter area, through said intake area, and said final discharge material, and thereby substantially eliminates paint overspray in areas surrounding said housing and the temporary overspray enclosure.

Abstract
A ventilation unit that can be sealed to an opening in a large temporary overspray enclosure employed during the painting of large yachts and marine vessels for containment of paint overspray, thereby substantially eliminating overspray in surrounding areas, a long sought-after objective in the industry. The unit is compact and self-contained, having a pre-filter area, primary filter material, an intake area, fans, a variable controller for each fan, an exhaust area, final discharge filters, and doors configured to seal the back end of ventilation unit during periods of non-use and which are removable during use or otherwise positionable to provide unobstructed airflow into the pre-filter area. The unit is also configured to be easily portable and reusable. A hose connection plate can also be used to connect one or more hoses to the pre-filter area to provide enhanced ventilation to high paint areas within the temporary overspray enclosure.
