EZ Pass-Thru Powder Booths

Parts enter the booth through the conveyor openings, then pass the coating operator stations to receive the coating. The powder overspray is entrained within the air stream moving to the collector module, where the cartridge filters will remove the particulate. The containment air is drawn through the air handler’s primary and final filter system before being discharged back into the room. Coated parts exit the booth for conveyance to the cure oven.

CONTROL EQUIPMENT

• NEMA 12 Remote Electrical Panel
• Primary Disconnect
• Automatic Purge/Pulse Control
• Main Air Line Disconnect
• Magnehelic Pressure Gauge
• UL / CUL Approved

ILLUMINATION

Lighting is provided by four Class I Division II, 48" long, fluorescent, 32-watt, T-8 type fixtures (four-tube), mounted behind safety glass; appropriately sealed from the interior of the spray booth. All fixtures are UL listed and approved for their intended use and placement.
NOTE: Lexan™ roof panels may be substituted for the light fixtures.

 PURGE CONTROL

This feature assures the safe operation of the coatings enclosure, by maintaining the airflow at design levels. During operation overspray powder accumulates on the cartridge filters. The term for this is “loading”; as the cartridge filters “load”, airflow decreases and suction pressure rises within the air handler. A timer activates a system of air purging valves that clear the cartridge filters of accumulated powder as needed.
