3A.4 Vehicle Paint Spray Booths (continued):
Piping Requirements: Piping diagrams include limitations on pipe length and fittings. System piping must be
balanced. Balanced piping is that in which the difference between the shortest actual pipe length from any%" TEE
to nozzle and the longest actual pipe length from any W TEE to nozzle does not exceed 10% of the longest actual
pipe length from any %" TEE to nozzle. Piping runs from the 1" TEE to each of the 3/" TEE's must be equal in
length. The number and type of fittings for all TEE to nozzle sections must be equal.
All piping must be Schedule 40, hot -dipped galvanized steel pipe, and all fittings must be 150 Ib. class, minimum.
Examples of acceptable fitting materials include hot -dipped galvanized malleable iron, ductile iron, or steel.
Couplings and unions may be used where necessary, and reducing bushings or reducing tees can be used for
changes in pipe diameter. Note: Black steel pipe and fittings can be used in relatively noncorrosive atmospheres.
3A.4.1 Work Area Coverage, VPSB
There are two distinctly different nozzle and piping arrangements for protecting the Work Area using the IS45ABC
cylinder. The first arrangement is "Standard Work Area Coverage", and the second is "Module Perimeter
Work Area Coverage" outlined as follows:
3A.4.1.1 Standard Work Area Coverage, VPSB
The Amerex Vehicle Paint Spray Booth System is flexible enough to protect a wide variety of Vehicle Booths of
various dimensions. The maximum booth height is 23'4". As noted, the IS45 cylinder is used with two or four
nozzles, and each of the nozzles has been tested to protect a Work Area Module. A Work Area can be thought of
as a series of 'boxes', or Modules, stacked together, each protected with a nozzle. The maximum parameters for
each Module are given as follows:
Module Volume: 1,050 ft.3 per nozzle, two or four TF nozzles per IS45ABC
Maximum Module Area: 105 ft.2 per nozzle for booths up to 10 ft. in height;*
45 ft.2 for booths at 23 ft., 4 in. height."
Maximum Module Height: 23 ft., 4 in.
Maximum Module Side Length:
Module Center: 14 ft. for booths up to 10 ft. tall*
9 ft for booths at 234' tall*
Booth Edge: 14 ft for booths up to 10 ft tall
Centerline: 15 ft. (widthwise); booth height limited to 10' tall with this option
*Note: For Module Center Installations with booth heights between 10' and 23'4", reference table 3A-1
Maximum Nozzle Offset — Module Center Entrv: Within a 2.5 ft. radius semicircle from center of module,
no less than 12" from any side of the module (booth); the curved portion of the semicircle must curve
away from the centerline of the booth; the tip of the nozzle within 6" of ceiling.
Maximum Nozzle Offset — Booth Edge Entry: Entry into the module at the closest point to the intersection
of the booth wall and ceiling. The nozzle location, horizontally, is at the midpoint of the longest side of
the module, +/- 2 feet. The tip of the nozzle must be within 6" of its entry point. This option is
allowable only for booths 10 feet or less in height.
Maximum Nozzle Offset — Booth Centerline Entry: This option is available where nozzle entry is only
possible along the centerline of the booth ceiling. Maximum booth height for this option is 10 feet.
This installation configuration allows for a maximum module side length of 15', which is the width of
the Work Area, in this case. There is no allowable nozzle offset for this option. The first and fourth
nozzles are to be located at 12" from the front and back of the booth, respectively. The second and
third nozzles are to be spaced equally between the first and fourth nozzles. The tip of the nozzle must
be within 6" of the ceiling.

one nozzle located at the edge of the module over the front end of the booth.
