A KELVA Cleanflow non-contact web cleaning system comprises of a web cleaner with integrated antistatic equipment, filter/ fan unit and connecting duct system.
The unique design of the KELVA web cleaner allows the system to clean both sides of the web simultaneously. The cleaner neutralizes the static charge and breaks down the boundary air layer, which holds the contamination to the surface of the substrate. A combination of pressure air and vacuum creates micro-vibrations on the surface of the web loosening and removing the contamination. The debris is extracted from the cleaning head and collected in the filter fan unit, which cleans and re-circulates the air for a very energy efficient solution.
A wide range of models are available to cover web cleaning for various applications and materials in web widths from 300 mm to 10 m so far.
KELVA offers cleaning solutions for specific webs such as paper, board, non-woven tissue, corrugated, glass, laminating and many more.
