For large ducts and high productivity
RAS has designed the DuctZipper in L-shape especially for large ducts and high productivity.
The RAS DuctZipper duct seaming machines reduce the traditional three steps (rollform the receiver lock, rollforming the flange and finally closing the seam) down to only one easy run through the machine. The result is a clean joint and an extremely tight duct.
Halved staffing needs due to easy handling of large air ducts
Doubled working speed due to fast workflow
Low physical strain on machine operators
Consistent long-term quality due to low machine wear
40-50% less space required (possible installation next to a wall)
Improved seam accuracy due to longer guide rail
Increased safety: Even large ducts keep their shape
Easy maintenance and cleaning due to good accessibility
