Anti-static brush 450 mm for laminators, inner width 500 to 615 mm - Kinetronics SWL-450

Unwinding plastic film generates static that pulls dust onto the web and shows up as inclusions in the finished job. The StaticWisk SWL-450 mounts magnetically inside the machine frame and cuts the charge near the mounting point to below 5 percent. Order by the inner width of the machine rather than by the 450 mm brush length. This size covers 500 to 615 mm.

Benefits

• Fits without rebuilding the machine: adjustable inner width of 500 to 615 mm, set at the magnetic feet on both brush ends.
• Measured discharge: under 5 percent residual charge near the mounting point, measured on polyethylene film at around 20 kV and 1 m/s.
• Stronger in pairs: one brush on the upper and one on the lower film pushes the potential at the contact point below 1 kV.
• No scratches on the film: ultra-soft conductive synthetic fibres, 40 mm long.
• Properly grounded: 3.5 m ground cable with cable lug for the machine frame.

Applications

Film that carries no charge runs flat off the roll, which makes the laminate smoother and keeps dust from settling between the layers. The manufacturer recommends one brush on the upper and one on the lower film, because only mounting on both sides brings the potential at the contact point under 1 kV. Use is not limited to laminators, the brush mounts the same way wherever static on film or paper causes trouble. The maximum operating temperature is 65 °C.

Mounting and care

The brush is clamped directly between the side cheeks of the machine frame. Unscrew the supplied screws out of the brush ends until the magnetic feet sit firmly against the frame. Then fasten the 3.5 m ground cable to the frame with its cable lug, without that connection the collected charge has no path to earth. For a bolted fixing as well, holes can be drilled in the upper section of the aluminium profile. A risk assessment before installation is advisable, and correct installation remains the responsibility of the operator.
