## Abstract

The present invention relates to accelerated directional airflows for use in, preferably, paint booths. Specifically, the present invention relates to apparatuses, systems, and methods of using the same that create an accelerated directional airflow while eliminating the requirement of having multiple vents, nozzles, hoses, and the like. Even more specifically, the present invention controls airflow more efficiently, requires fewer parts, and costs less to use and maintain. Specifically, the accelerated directional airflows are useful in paint booths for drying painted parts and for ventilation.

## Claims

### Claim 1

A paint spray booth comprising:
an enclosed space surrounded by walls, a ceiling, and a floor, wherein mounted on a first wall is a first airflow apparatus, said first airflow apparatus comprising a first intake housing comprising a first air intake, a first air mover within the first intake housing configured to direct a first airflow through the first intake, a first hollow extension protruding from the first intake housing, the first hollow extension having a first surface, a length and a width perpendicular to the length wherein the length is greater than the width, and a volume therein, wherein the first hollow extension is mounted to the first wall such that the length of the first hollow extension is disposed horizontally on the first wall adjacent to the ceiling, wherein the first surface is flat and comprises an elongated first slit in the first surface of the first hollow extension running a direction of the length of the first hollow extension and wherein a first directional airflow element is disposed on the first surface of the first hollow extension, wherein the first air mover directs the first airflow through the first intake, into the first hollow extension, out the first slit of the first hollow extension and through the first directional airflow element of the first hollow extension forming first accelerated air and directing the first accelerated air into the enclosed space; and
a second airflow apparatus comprising a second intake housing comprising a second air intake, a second air mover within the second intake housing configured to direct second airflow through the second intake, a second hollow extension protruding from the second intake housing, the second hollow extension having a first surface, a length and a width perpendicular to the length wherein the length is greater than the width, and a volume therein, wherein the second hollow extension is mounted such that the length of the second hollow extension is disposed horizontally adjacent to the ceiling, wherein the first surface of the second hollow extension is flat and comprises an elongated first slit in the first surface of the second hollow extension running a direction of the length of the second hollow extension and a first directional airflow element is disposed on the first surface of the second hollow extension, wherein the second air mover directs the second airflow through the second intake, into the second hollow extension, out the first slit of the second hollow extension and through the first directional airflow element of the second hollow extension forming second accelerated air and directing the second accelerated air into the enclosed space;
a ventilation system comprising a third air mover in airflow communication with an upper space above the ceiling of the enclosed space, the ceiling having a plurality of vents each of the plurality of vents providing airflow communication between the upper space and the enclosed space,
wherein a first vent of the plurality of vents is positioned in the ceiling, the first vent of the plurality of vents forming a first downdraft airflow generated from the third air mover directing air into the upper space and through the first vent of the plurality of vents, the first vent positioned so that the first downdraft airflow from the first vent of the plurality of vents is directed into the path of the first accelerated air forced from the first airflow apparatus, and
wherein a second vent of the plurality of vents is positioned in the ceiling, the second vent of the plurality of vents forming a second downdraft airflow generated from the third air mover directing the air into the upper surface and through the second vent of the plurality of vents, the second vent positioned so that the second downdraft airflow from the second vent of the plurality of vents is directed into the path of the second accelerated air forced from the second airflow apparatus;
an object within the enclosed space configured to be painted,
wherein the first accelerated air forced from the first airflow apparatus is configured to combine with and interfere with the first downdraft airflow from the first vent of the plurality of vents in the ceiling to form a first turbulent airflow within the enclosed space above the object and directed downwardly at the object, and the second accelerated air forced from the second airflow apparatus is configured to combine with and interfere with the second downdraft airflow from the second vent of the plurality of vents in the ceiling to form a second turbulent airflow within the enclosed space above the object and directed downwardly at the object;
a second slit in the first surface of the first airflow apparatus, wherein the first air mover directs the first airflow through the first intake, into the first hollow extension, and out the second slit;
a first air diffuser disposed within the first hollow extension of the first airflow apparatus, wherein the first air diffuser comprises at least one hole for the first airflow to pass therethrough, said first air diffuser disposed between the first intake housing and the first slit of the first airflow apparatus; and
a second air diffuser within the first hollow extension of the first airflow apparatus, wherein the second air diffuser comprises at least one hole for the first airflow to pass therethrough, said second air diffuser disposed between the first slit and the second slit of the first airflow apparatus.

### Claim 2 (depends on 1)

The paint spray booth of claim 1 wherein the first and second slits in the first surface of the first airflow apparatus are adjacently disposed in the first surface.

### Claim 3 (depends on 1)

The paint spray booth of claim 1 wherein the second slit of the first airflow apparatus comprises a second directional airflow element disposed over the second slit, wherein the second directional airflow element of the first airflow apparatus comprises a first flange extending from the first surface on a first side of the second slit of the first airflow apparatus and a second flange extending from the first surface on a second side of the second slit of the first airflow apparatus.

### Claim 4 (depends on 1)

The paint spray booth of claim 1 wherein the first surface of the first airflow apparatus is angled downwardly toward the floor to direct the first airflow toward the floor.

### Claim 5 (depends on 1)

The paint spray booth of claim 1 further comprising:
a filter associated with the first air intake for filtering air forming the first airflow.

### Claim 6 (depends on 1)

The paint spray booth of claim 1 wherein the object is a vehicle.

### Claim 7 (depends on 1)

The paint spray booth of claim 1 wherein the first directional airflow element of the first airflow apparatus comprises a first flange extending from the first surface on a first side of the first slit of the first airflow apparatus and a second flange extending from the first surface on a second side of the first slit of the first airflow apparatus.
