Dust Type: Powdered Metal Dust and Smoke
(1) Donaldson/Torit Model DFT-3-24 with TBI-20, 20 h.p. Direct Drive Blower, explosion relief vents
Blower outlet dampers and silencers were used.
Filter type was Donaldson/Torit Ultra Web Flame Retardant.
Airflow/Static Pressure: 3 systems each 3,000 cfm @ 10 s.p., 1 system at 6,000 cfm @ 12 s.p.
Application Solution: Dust collectors connected to individual metal spray booths and provided direct exhaust to each booth hood enclosure.
Ducting connections were done with clamping duct material. Due to a mixture of gasses in the air stream, filtered air was not recycled.
Dust collectors provided booth visibility control, operator breathing zone isolation and emission standards were met.
