Our Spray Walls Are Perfect For Small Parts and Spaces
Our powder spray wall plenums are a perfect fit for the powder coater looking to save floor space and still get the perfect finish on small parts, wheels, and frames. Designed to control powder overspray when a conventional powder booth isn’t the best choice.
Construction
The booth walls and roof are made of 18 gauge or thicker steel that has been G90 galvanized. The booth utilizes a single panel design. The walls and roof are connected via a track system. The booth is bolted together and the exhaust system is integrated into one or more of the booth’s walls. Threaded inserts in key parts help simplify assembly. No field welding is required.
Lighting
The spray enclosure includes roof-mounted light fixtures designed to accommodate four standard 48” T-8 bulbs. These fixtures are mounted on special panels that include factory-provided reinforcement. The light fixtures are mounted in the field over sheets of ¼” tempered safety glass that are sealed in place. The light fixtures are accessible only from the booth’s exterior.
Typical Powder Spray Wall Exhaust Unit
The exhaust unit is included in the exterior dimensions for the booth. The booth uses either one or two floor mounted exhaust units. The exhaust unit is constructed of primarily 16 gauge and 18 gauge G90 galvanized steel. The exhaust system utilizes a belt-driven tubeaxial fan and includes a twostage or three-stage filter system to draw air through the booth enclosure which will either exhaust the air to the outside or return it to the shop atmosphere. The exhaust unit uses an ASHRAE/NESHAP type system consisting of a primary blanket filter, a set of polyester cube filters and a set of HEPA type final filters. The exhaust unit is designed to draw air from the lower 1/3 of the wall of the booth, resulting in semi-downdraft airflow. The booth ships with tackified 1” blanket type pre-filter media, 24”x 24” x 12” duo-ply polyester cube filters, and optional 24”x 30” x 6” true MERV 17 HEPA filters with integrated galvanized metal housings.
Controls
The booth is operated via a simple control panel in a NEMA enclosure. The control panel allows the operator to stop and start the exhaust fan and turn the lights on and off. The control panel includes over-current protection. Upgraded models include adjustable airflow via a face-mounted VFD control knob.
Outsourced Components for Powder Spray Walls
Exhaust duct is not required when HEPA filters are used. Parts for electrical service connection to the control panel and field wiring components are provided by other companies & are not considered part of the deliverable
