Contact Cleaning

KELVA contact cleaners are available for both single- and double-sided continuous contact web cleaning. Specially developed polymer rollers lift and transfer contaminations from the web surface to easily replaceable adhesive sheets.
The polymer roller is designed to give a very good contact to the web – even at low pressure. The active static discharger, located after the rollers, ensures that the web does not re-attract dust after passing through the cleaner.

KELVA Contact Web Cleaners are suitable for cleaning of coated (glossed) paper, film and foil with low dust levels, web speeds up to 400 m/minute and web widths up to 2.500 mm. They are operated pneumatically. Available for cleaning of one, or both sides, of the web.
