Printing - PERIPHERALS - WEBCLEANING - NON-CONTACT cleaners
The Kelva non-contact web cleaner is universal. It is suitable for all types of material, from low to high levels of dust and contaminations, web speeds up to 2000 m/min and widths up to 5000 mm.
Operation is manual or pneumatic. Cleaning of both sides of the web is standard.
A Kelva web cleaning system consists of a non-contact web cleaner head with passive or active antistatic equipment, a filter-fan unit, a dust collecting filter and control unit.
The web itself and the collected contamination on the surface is deionised by a noncontact static discharger, located above and across the incoming web.
To penetrate the moisture layer the filter-fan unit generates pressurised warm air, which when blown through the air slot in the cleaning head reduces the surface tension and allows effective dust removal.
Finally, the patented cleaner head design allows penetration of the boundary air layer by directing turbulent air towards the web. This unique technology creates micro-vibrations on the web surface, causing the particles to loosen and allowing the vacuum air to remove them through the vacuum slots. These three cleaning actions are unique to the KELVA design and achieve the most effective web cleaning known of the time of writing.
