The improved Super Collector E2-vfd, a portable vacuum collection system, is a powerful, compact collector. According to the manufacturer, it sets new performance (suction) and productivity standards, making it a good choice for all types of commercial air duct cleaning. The enhanced Super Collector E2 vfd features a 5,000-cfm (free air) fan which, together with the 2-hp motor and variable-frequency drive, delivers 4,500 cfm when measured at the inlet. This performance (suction) enables contractors to isolate and clean longer duct runs with one hookup for improved productivity and profits, says the company.
