POWDER PAINT INDUSTRY

Let's Get Specific

Contaminant Characteristics

Contaminants from powder painting processes range from medium to light, fine particulates and fumes. Some contaminants may be hygroscopic or agglomerative when exposed to moisture.

Powder Paint Contaminant Hazards

Worker Inhalation and exposure to contaminants is an important concern on powder paint applications. Most materials commonly used in powder paint applications are combustible and / or explosive posing a significant threat to workers and to facility safety.

Design Approach for Powder Paint Contaminant Control

Powder paint rooms are generally designed where the industrial ventilation controls maintain a negative pressure relative to the adjacent rooms to contain the contaminant locally. Hoods within the painting equipment are designed to capture any powder that does not adhere to the target and then may pass through cyclone dust collectors to reclaim the material. Any contaminant not reclaimed is conveyed into the dust collection system where it is captured. The clean filtered air is returned to the painting area to minimize workload of air conditioning system and maintain constant pressure.

Industrial filtration solutions for powder paint processes may also require special options or accessories to improve the safety and reliability of the system. Bag-out options for consumed filters and collection drums may be used to limit exposure of collected material when performing system maintenance. Additional features such as duct and equipment clean-out doors are utilized because the safety after filters.

Fire retardant cartridges, sprinkler connections, explosion vents, suppression systems, duct isolation devices, or other safety devices are common when handling combustible and or explosive materials.
