Spray Booth

ISTpaint specializes in the engineering, manufacturing, installation, and servicing of custom-made Paint Booths, mixing rooms, and finishing systems of any sizes and configurations. Our systems are used in a variety of industries where high-quality finishing is required. Our spray booths provide a controlled environment for industrial surface preparation, painting, coating, and finishing applications.

Our paint booths can be designed with a filtration and exhaust system to provide a clean, ventilated source of air which keeps the spray chamber free of dust, fumes and overspray. According to the surrounding climate, an air makeup units (AMU) can provide temperature controlled fresh air for the booth in order to ensure an optimal curing environment.

All spray booth systems and components meet or exceed codes and compliance for CSA, OSHA, NFPA, ANSI, as well as most local building codes and fire codes. A system certification can be obtained upon request.

Booth Features

  • Heavy Duty Construction: Fabricated with the highest quality 18 gauge, G90 galvanized steel panels.
  • Easy Assembly: All designs create a bolt-free booth interior, while panels and support members are precision-punched for easy nut and screw assembly.
  • Superior Doors: Product Doors are field located on slotted hinges to facilitate adjustment on 2-axes for uneven floors. Our personnel doors are 30” wide X 84” tall, with a 14 ½” wide x 48” tall observation window built into a preassembled heavy frame.
  • Industry-Leading Lighting: Lighted booths receive full, bright booth illumination from standard LED ISTpaint light fixtures. ISTpaint light fixtures are CSA listed (Class 1 Division 2).
  • Paint arrestors: High efficiency RP Paint Arrestors which have a custom designed layering system to increase the overall efficiency of the booth. Filters are lab tested with over an 99% particulate removal efficiency.
  • Efficient Fans and Motors: Quality brand name tube axial fans and motors.
  • Air Solenoid Valve Interlocked to the exhaust fan and air supply for the spray application equipment.
  • Meets Quality Performance Standards: Spray booths manufactured by ISTpaint meet and/or exceed all applicable OSHA and NFPA regulations.

Air Make-Up Unit (AMU)

Air make-up units (AMU) are used to replenish fresh air into the paint booth to stabilize its pressure as air is being exhausted. Direct-fire heaters and other energy-efficient technologies can be added to AMU to supply temperature-controlled air into the spray booth in order to provide painters with a comfortable work environment, as well as to accelerate the paint drying/curing time.

Air Make-Up Unit - ISTpaintISTpaint offers a variety of energy-saving Air Make-Up configurations which can minimize the operation costs of the paint booth by taking into account key factors affecting the air quality – such as the size of the booth, local climate, cycle times, and temperature set points. Our units can come factory-set in either positive or negative pressure configurations and can be field-adjusted to accommodate the full range of application duties that may be required.

Spray Booth Types Available

Crossdraft Spray Booths

Crossdraft booths, the simplest configuration, are efficient and economical, and best suited for coating industrial/ large equipment, truck, and wood applications.

ISTpaint crossdraft spray boots take in fresh air through filters in the product doors. The clean, filtered air is drawn through the booth and exhausted through a filter system at the opposite end.

Modified Downdraft Spray Booths

Offering a clean and healthy work place, modified downdraft spray booths allow for easy pressurization with the addition of an intake plenum with a fan or a heated air makeup unit. The modified downdraft takes in air from the cleaner upper levels of the shop through a filter bank located in the booth’s ceiling, near the product doors.

The filtered air is drawn down through the booth to an exhaust filter system at the other end, and is optionally equipped with a pre-filter plenum for additional intake air filtration.

Side Downdraft Spray Booths

A more economical solution for shops that are unable to install a pit, side downdraft spray booths take in fresh air from the cleaner upper levels of the shop through a filtered booth ceiling. The filtered air is drawn down and away from the product through exhaust filters at the floor level along both sides. This provides efficient overspray control that reduces prep time while also delivering a healthier work place environment.

The side downdraft booths can also be purchased with a pre-filtered plenum or a pressurized intake plenum, and can be equipped with an air replacement unit and cure cycle to meet your requirements.

Downdraft Spray Booths

Providing the best airflow style, downdraft booths offer efficient overspray control which reduces prep time and also provides a much healthier workplace environment. Downdraft booths take in fresh air from the cleaner upper levels of the shop through a filtered booth ceiling. The filtered air is drawn down and away from the product, into the filtered exhaust pit located in the floor.

This booth can be purchased with a pre-filtered plenum or with a pressurized intake plenum. It can also be equipped with an air replacement unit and cure cycle to meet your requirements. An optional above ground basement exhaust plenum is available for installation without concrete work.

Drying room

Drying RoomDrying Rooms provide the ideal controlled environment for your finishing, curing, and drying requirements. Diverting freshly coated parts into a separate drying room not only allows for continuous spraying operations inside the paint booth, but it also provides a clean, filtered atmosphere for an optimal drying and curing process, along with reducing overall operating costs and increasing productivity.

Drying Rooms can be drawn to the customer’s specifications and be equipped with infrared and/or convection curing systems according to applications and coating requirements.

Waterborne Paint Drying System

ISTpaint’s waterborne paint drying system produces the ideal turbulence inside the booth that will accelerate drying time and keep freshly coated parts away from dust and airborne contaminants. It can easily be fitted into a paint booth of any sizes or a standalone drying room.

This waterborne paint drying system takes air from the spray booth cabin through an intake filter controlled by a blower. The air is then delivered evenly onto the painted surface from a set of nozzles horizontally mounted at the gable of the spray booth.

Our exclusive design uses two patented technologies to create the perfect turbulence:
