We spoke with Asa Halliday of Tri-Mer about designing and operating an effective exhaust system for facilities with finishing lines, including scrubber maintenance.

Halliday discussed maintaining appropriate gas velocities throughout the system and the need for an effective source capture / local exhaust ventilation.

He also discussed how shops could use a mist eliminator in hoods to keep ductwork clean and about ductwork velocities to minimize material fallout. 

“Emission controls are not something that necessarily make money or optimize processes, but certainly, it's something you need to take care of,” Halliday says. “And if it's done appropriately, it minimizes downtime, which can improve your process overall.”
