Abstract
A spray booth comprises a housing having a ceiling and a set of walls that each have a bottom end and a top end, with the walls and the ceiling defining an interior. An air intake is disposed in the ceiling, and an exhaust outlet is disposed near the bottom end of one the walls. A circulation system is used to introduce air into the interior through the intake and to exhaust air through the outlet. Further, the air intake is configured to produce a airflow gradient within the interior such that the flow rate decreases in a direction toward the outlet and such that the airflow through the interior is in a generally downward direction.
Claims26
A spray booth comprising:
- a housing comprising a ceiling and a set of walls that each have a bottom end and a top end, wherein the walls and the ceiling define an interior;
- an air intake in the ceiling;
- an exhaust outlet near the bottom end of one of the walls;
- a circulation system to introduce air into the interior through the intake and to exhaust air through the outlet;
- wherein the air intake is configured to produce an airflow gradient within the interior ceiling such that the flow rate decreases in a direction toward the outlet and such that the airflow through the interior is in a generally downward direction.
A spray booth comprising:
- a housing comprising a ceiling and a set of walls that define an interior;
- an air intake and an exhaust outlet to permit air to be flowed through the interior;
- at least one intake fan disposed in the ceiling;
- at least one exhaust fan to exhaust air through the exhaust outlet;
- and
- a heater disposed in the ceiling upstream of the intake fan.
A spray booth comprising:
- a housing comprising a ceiling and a set of walls that each have a bottom end and a top end, wherein the walls and the ceiling define an interior;
- an air intake in the ceiling;
- an exhaust outlet near the bottom end of one of the walls;
- a circulation system to introduce air into the interior through the intake and to exhaust air through the outlet, with the air flowing through the interior in a generally downward direction;
- and
- a filter tower vertically positioned over the outlet, wherein the filter tower includes a set of generally vertically oriented filters.
A method for spraying an object, the method comprising:
- providing a spray booth comprising a housing having a ceiling and a set of walls that each have a bottom end and a top end, wherein the walls and the ceiling define an interior, an air intake in the ceiling and an exhaust outlet near the bottom end of one of the walls;
- passing air into the interior through the intake such that an airflow gradient is produced within the interior, with the flow rate decreasing in a direction toward the outlet and with the air passing through the interior in a generally downward direction;
- exhausting air from the interior through the exhaust outlet;
- and
- spraying an object that is disposed within the interior while the air is flowing through the interior.
