Powder coating is an eco-friendly finishing technique that delivers a tough, attractive, and durable finish. Its application involves using a special powder spray gun, which imparts an electrostatic charge to the powder particles once they move through it. Since the products being finished are grounded, the powder gets attracted to them thanks to the electrostatic process. When the application is complete, the parts are then moved to a curing oven that sets to work by melting and crosslinking the powder coats over their surface. The end result is a tough, scratch-resistant, and attractive finish. Powder coating may be applied to a wide variety of substrates including metals, plastics, wood, and more. Let us now take a closer look at the key powder coating techniques you could choose from.
Powder coating spray booth
Our powder coating spray booth is partly designed to contain overspray and other contaminants and keep the finishing area clean. It also offers a well-illuminated space where powder coating may be performed with enhanced precision. This sort of paint booth comes complete with either a single or multiple exhaust fans and intake and exhaust filters that set to work by capturing overspray and other contaminants. This combination of exhaust fans and filters makes sure the airflow created in the unit keeps overspray within the workspace and allows the operators to see what they are doing. Should your facility have welding or blasting areas, a powder coating spray booth may feature filtered doors that will help keep airborne contaminants away from the substrate’s powder-coated finish.
Powder coating clean rooms
Should you have to enforce strict finish requirements, you will certainly need a cleanroom that is otherwise known as an environment room. Essentially, this is a climate-controlled enclosure which is constructed surrounding the powder application area. Its main function is to do away with airborne contaminants. While, at the same time, regulating both temperature and humidity of the booth during the powder coating process. In turn, this helps in preventing any kind of contamination, clumping, or finish consistency problems. A cleanroom is usually a very effective solution if the substrates you want to be finished need exact specifications for adhesion or even salt spray tolerance.
Apart from our powder coating booths, we offer standard and customized paint booths that integrate a variety of airflow styles and are designed for varying applications. ZPar International also offers abrasive blasting equipment and diverse accessories like make-up air heaters, filters, control panels, boost lifts, and more!
Our powder application booths are built in the USA specifically for powder coating use. With over 150 standard models our spray walls and batch booths are great for any size, including shops working with auto, truck and motorcycle related coating jobs. We also offer larger booths for aviation and heavy equipment coating systems. Immediate delivery available on many common sizes. Options include VFD controls, solid or filtered doors, and true HEPA filtration. Custom sizes, conveyors, and fire suppression integration also available.

Powder Coating Spray Booth Features
Booth 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.
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 tube axial fan and includes a two stage 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
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.
