SFS Intec manufactures a wide variety of screw fasteners that are used in the residential and commercial building markets. SysTech Design developed an effective dust control system that integrated an exhaust hood/duct into the automated assembly machines. The exhaust hoods capture the dust at the source and convey it to a properly sized Donaldson® Downflo® dust collector where the zinc dust is removed from the air stream. The clean air then travels thru a HEPA final filter and is returned to the air-conditioned work area.
