Air Knives

Bronx "Next Generation" Air Knives have been developed to achieve the low coating mass requirements at higher speeds demanded in today’s marketplace. At the same time, higher coating mass can be produced as required. The next generation design achieves the smooth laminar air flow required to achieve the coating and ensure a high quality surface.

Next Generation Air Knives
     - Designed for line speeds up to 185 mpm
     - Coating weights from 40/m2 to 350g/m2 (both sides, subject to line speed & coating type)
     - Strip widths up to 1500mm
     - Differential coating capability
     - Compact design allowing excellent pot access
     - Hardened alloy steel and chrome plated air knife lips to maximize operational life
     - Edge Baffle System to minimize coating build up  on strip edges (required for slower production & heavier coating mass)

    Controls and Adjustments include:
     - knife to pot vertical (adjustment via servo motor)
     - Knife to strip horizontal (adjustment via servo motor)
     - Knife angle of attack (manual adjustment)
     - Knife jet gap (Ore-set offline to meet production requirements)
     - Air knife gap cleaning device (auto programmed for welds or operator initiated via HMI)

    Options:
     - Air Knife gap maintenance & calibration stands
