PREP & SUPPORT — MIXING ROOMS
Pairs with our PFS Core Control Panel — UL 508A certified with spray, flash, and cure modes. Programmable cycle timers, safety interlocks, and optional BMS integration.
High-efficiency, UL listed tube axial fans provide consistent ventilation and exhaust airflow — keeping solvent vapors below hazardous levels at all times.
Class I Division 2 inside-access four-tube light fixtures (fluorescent or LED tube compatible). Optional LED upgrade available. Uniform, shadow-free illumination for accurate color matching.
Exhaust uses fiberglass media filters. Intake uses tacky-type filters standard. Blanket intake upgrades available for heated configurations.
Structural panels available in galvanized or powder coated finish. Built to NFPA 33 standards with air quality and OSHA compliance on every unit.
All standard mixing rooms ship with a 1/2 HP motor providing reliable exhaust ventilation. Sized to maintain safe vapor concentrations across all standard room depths.
12″ exhaust duct on all models. Connects directly to your existing exhaust stack or can be routed through the roof or wall with standard HVAC fittings.
Every mixing room includes one 3′ × 7′ personnel door with window for visibility and safe entry. Positive-pressure door seal keeps vapors contained.
PFS mixing rooms ship to all 50 states. Factory-direct pricing, fast lead times, and dedicated project support from order through installation.

NFPA 33 sets specific limits for rooms used to mix flammable and combustible liquids. They include a maximum floor area of 150 sq ft, an enclosed room with spill containment, a cap on the liquid kept inside of 2 gallons per sq ft, and mechanical ventilation of at least 1 cfm per sq ft or 150 cfm (whichever is greater) running whenever the room is in use. They also require electrical classification, automatic fire protection, and portable extinguishers. Your local fire official makes the final call, so confirm the requirements for your jurisdiction.
Start with how much paint you mix and keep on hand. The MR6 suits a single-booth shop; the MR12 and MR15 add bench space, storage racks and room for a mixing system. All four standard models stay under the 150 sq ft limit.
Mixing rooms usually sit directly beside the booth so painters walk a few steps, not across the shop. They can stand alone or integrate with the booth wall and share its exhaust.
Tube-axial fans with a 12″ exhaust duct keep air moving through filtered intake and exhaust, and the controls interlock ventilation with lighting and the shop’s fire protection.
Class I Division 2 light fixtures give accurate color matching, and the electrical inside the room is specified for its hazardous classification.

An industrial paint mixing room provides a dedicated, code-compliant space for paint preparation, thinning, color matching, straining, and storage of flammable liquids. Continuous cross-flow ventilation removes paint and solvent fumes, keeping the environment safe for workers and compliant with OSHA, NFPA 33, and local fire codes.
Yes. Paint mixing rooms used for the preparation and storage of flammable coatings are subject to NFPA 33 requirements. PFS mixing rooms are built to NFPA 33 standards with ETL/UL listed and certified components, OSHA compliant cross-flow ventilation, and a built-in 4-inch containment base for spill capture.
An integrated mixing room is built as part of the spray booth system — sharing a common wall with the booth and delivered as a single unit. A stand-alone mixing room is a self-contained unit that can be placed anywhere in your facility. PFS manufactures both configurations. Integrated rooms offer the advantage of single-source delivery, installation, and accountability.
Yes. PFS manufactures mixing rooms in standard and custom sizes. Standard configurations range from 8′ x 8′ to 12′ x 16′, but custom dimensions are available for non-standard facility layouts. Contact a PFS engineer for a custom quote.
PFS mixing rooms use a cross-flow ventilation system that continuously draws fresh air through intake filters on one wall and exhausts through filters on the opposite wall. This constant air exchange removes paint fumes, solvent vapors, and particulates, maintaining a safe working environment and complying with OSHA and NFPA 33 ventilation requirements.
Standard PFS mixing rooms are 9′ wide × 8′ high and 6′, 9′, 12′ or 15′ deep. Pick by the amount of paint you mix and store; all standard sizes stay under NFPA 33’s 150 sq ft limit for mixing rooms.
NFPA 33 calls for at least 1 cfm per sq ft of floor area or 150 cfm, whichever is greater, running whenever the room is in use. PFS mixing rooms are designed to meet it.
