With hundreds of A.C.T. dust collectors manufactured and installed, every serial number is a statement of quality. Lifting lugs are engineered to the correct lifting angle and formed doors for maximum rigidity, coupled with deep one-piece gaskets, maintain the seal. Angle iron support structure and base plates are pre-punched for easy installation. A fastener kit is included with Grade 5, zinc-plated fasteners. A premium blast, prime and paint process ensures the system will remain in excellent cosmetic condition for many years.
