Modern manufacturing spray paint booths deliver the most cost-effective mix of profitability and convenience - from individual, bench-style paint booths to multi-sectioned conveyor systems. In general, they differ based on three primary characteristics: cabin style, airflow, and air pressure.

Powder Coating Aluminum Extrusions

The booth, sometimes known as the cabin, is either open faced or enclosed. Enclosed models feature a system of circulated air that's either downdraft, semi-downdraft, side-draft, or cross flow. Open face booths remove airborne particles through an industrial grade fan that vents through a roof-mounted exhaust stack, expelling filtered air back into the shop environment. The air pressure within the work area is either positive or negative depending on the manufacturing process.

Constructed from 18-gauge galvanized steel, most are sold as a complete package that often requires self-assembly. In addition to kits, individual components can be incorporated into existing systems to replace worn or outdated components.

Fully customizable through quality manufacturers like Global Finishing Solutions and Spray Systems Inc., modular paint booths are also designed for specific uses that fall within a variety of industrial applications. Among the most popular are: automated manufacturing processes, powder coating, and metal manufacturing.

Automated / conveyorized manufacturing

When selecting the best spray paint booth for inclusion into a conveyorized manufacturing process, there are a number of things that have to be factored into the purchase decision. These include:

Automated Manufacturing Booths
Size Width Height Extension Length Options 48" 4-Tube Fluorescent Light Fixtures Estimated Cost
Small 5' 8' 2' 6, 5', 7' 6" 1 $2,000 - $3,000
Small 7' 8' 2' 6, 5', 7' 6" 2 $2,200 - $3,000
Mid-Size 12' 10' 2' 6, 5', 7' 6" 2 $3,400 - $4,300
Mid-Range 16' 10' 2' 6, 5', 7' 6" 2 $3,900 - $4,600
Large 20' 12' 2' 6, 5', 7' 6" 4 $5,300
Large 24' 12' 2' 6, 5', 7' 6" 4 $5,700 - $6,000

Powder coating

Powder coating is a finishing process that uses a negative electrically-charged current to "attract" the paint or sealant onto the product. Held in position through this electric charge, the part or product is then baked at high temperatures to permanently cure the finish onto the surface.

Many powder coating setups come complete with spray system, spray-to-waste booth, and the electric oven - accounting for the extended floor space requirements you'll notice below. Though there are a number of different sizes, power coating systems typically fall into three general categories based on the size of the parts intended for curing:

Powder Coating Sizes
Size Dimensions (W-H-L) Required Floor Space Fan Estimated Cost
Small 3' 8" x 7' x 5' 8" 19' x 19' 208/240 or 460/480 VAC, 3-phase $18,000
Mid-Range 10' x 9' x 11' 25' x 30' 208/240 or 460/480 VAC, 3-phase $36,000
Large 10' x 9' x 22' 36' x 30' 208/240 or 460/480 VAC, 3-phase $48,000

Metal manufacturing

Cross flow and semi-downdraft airflow designs are used extensively throughout metal manufacturing and epoxy coating for their combination of efficiency and safety. In particular, they are relied upon to control the powder, paint, and other airborne particles that would otherwise threaten worker safety. In addition, sprayed materials are often extremely flammable. An enclosed airflow design eliminates high concentrations of these materials and greatly reduces the risk of fire or explosion.

Ventilation Types

Comparing the two, cross draft airflow draws air from filters built into the product entry doors, pulling it through the length of the booth and into an exhaust chamber. In contrast, semi-downdraft airflow pulls air through filters in the ceiling as well as the product entry door, providing a higher degree of over spray control. The semi-downdraft design also cuts the amount of prep required while eliminating the need for costly exhaust pits.

Equally suited to metals ranging from wrought iron to stainless steel, common configurations include:
