250+ Standard Powder Spray Booth Models.  Choose Yours.

Any Size or Application, We’ve Got You Coated.

With over 250 standard models, we have booths that are well matched to any application. We offer small booths for coating wheels and cycle frames. Our walk-in booths are great for coating objects like railing or fence panels. They’re also perfect for spraying large batches of parts.

We also build larger booths that are used with aviation and heavy equipment coating systems. Options include VFD airflow control, solid or filtered doors, and cartridge or true HEPA filtration. Custom sizes, conveyors, automated spraying, reclaim systems and fire suppression integration also available.

Get the Size and Airflow That’s Just Right For the Way You Spray.

No matter what your finishing application requires, our powder spray booths can be sized and configured for your specifications. Our standard models come with rear-mounted filtration to keep your cabin clear of particulate and is perfect for batch coating operations. If your line requires continuous process throughput, we also provide crossflow and double-crossflow-style spray booths. These ‘tunnel-style’ powder booths can be used in a batch setup or can be equipped with an automatic powder gun array and conveyor in one of our automated finishing systems. Contact one of our systems experts today to discuss which option is the best solution for your application.

Technical Specifications For Powder Spray Booths


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.


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.

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.

Control Panels

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

Exhaust duct is not required when HEPA filters are used. Light bulbs, parts for electrical service connection to the control panel, and field wiring components are provided by other companies and are not considered part of the deliverable.

Delivery & Installation

Reliant equipment delivers unassembled. Reliant has hundreds of systems in operation around the world successfully installed by our clients, but we know that some of our clients need to be up and running as quickly as possible.
