KELVA Inventor of Web Cleaning


KELVA TLX efficient dust elimination without contact to material webs.

This non-contact web cleaner efficiently removes contaminants from almost any material surface – smooth or porous, robust or delicate.
It removes dust from webs in any application and covers web widths up to 3000 mm as standard. It can be easily customized for wider webs.

One web cleaner model for any application, material surface and web width: the universal TLX makes dust elimination on point, while maximizing production efficiency.

The KELVA non-contact web cleaner type TLX is suitable for medium to wide web widths and cleans almost everything, which makes you flexible for processing different sizes and materials.

This versatile web cleaner features a very powerful airflow of both, vacuum and blowing air, as well as integrated antistatic bars, so that dust and particles from even very wide webs will be removed on boths sides in an extremely efficient way.

Your whole production environment gets clean and thus a high quality of your end-product will be assured. If the materials continue to be finished, their dust-free state will highly reduce any maintenance and cleaning cycles of the subsequent production machinery.

Here is, where you should have your dust: in the dust bin!

The dust sucked is collected in the dust bin of the filter-/fan unit after automatic cleaning of the filter plates. Every 20 seconds the dust is dropped off into the collection tray, which can be easily emptied.

Get your ROI in less than a year!

When investing in a KELVA web cleaning system you will soon have the benefit of large improvements in production hours. Removing contamination from material surfaces improves quality for finishing processes and of the end products.

Once installed, it reliably will eliminate the dust and debris for many years.

We help you to analyze the dust-load related to your specific materials, machine settings and processing interfaces, so that you can find the right web cleaner for your needs.

The KELVA Non-Contact Web Cleaning Principle

During non-contact web cleaning the surface of the material won’t be physically touched. Instead a combination of underpressure, blown air and ionisation is used to remove any loose particle from the surface of the web.

This is the ideal method for extracting varying dust loads and particles depending on material, processing interfaces and finishing purposes.

A KELVA non-contact cleaning system includes a web cleaner with integrated antistatics, a filter/fan unit and connecting duct system. It can be easily installed into all types of R2R-production machines, be it new machines or as retrofits in existing production systems.

Developed with KELVA’s knowledge and experience gained from more than 7000 installations worldwide in web cleaning and most different industrial R2R applications.

KELVA Web Cleaner

Web cleaner of the TL-series follow the non-contact cleaning principle and remove the debris from both sides of the material surface. The web cleaning system offers an integrated anti-static device, infeed plate and grid.
Automatic adjustment functions allows cleaning of material with various thicknesses. Configurations can be adapted to any specific demand and web width.

KELVA Filter-/Fan Unit

Filter-/fan units consist of two parts: The upper part includes the ventilator providing the blowing air and the suction air for the whole web cleaning system. In the lower part the filter plates are installed for collecting the dust. They will be automatically cleaned by a jet pulse de-dusting system.The dust finally falls down into a dustbin. The filter area can be adapted to bigger dust loads and various web widths.

KELVA Non-Contact System

KELVA non-contact cleaning systems include a web cleaner head incl. integrated antistatics, a filter/fan unit and a connecting duct system. The cleaner head ideally is installed before and after critical processes for extrac-ting the dust and particles and thus making clean the product surface for a next production- or finishing step. The filter/fan can be installed farther away, dependig on the space conditions on site.
