High-performance filter systems from KELVA are an important component of non-contact web cleaning systems, as they ensure a constant supply and removal of air depending on the width and speed of the web and the type of material to be cleaned. The filter model and size also depend crucially on the dust load, which determines the filter surface required to capture all dirt particles efficiently.

The cleaning head and filter systems form a complete system that is customized for the respective production conditions. This is why KELVA offers different filter systems with different motor sizes and filter surfaces to always generate the right air flow. The models all have automatic filter cleaning with antistatic filter media. This ensures that dust and dirt particles are reliably collected in the dust garbage can, which is also part of the filter/fan unit.

A control cabinet ensures automatic operation.The filter units can be installed close to the machine on which the non-contact cleaning head is mounted or further away, depending on local conditions. Modular connection systems can be used to flexibly bridge any distance.

Choosing the right filter/fan unit
The width of the material web to be cleaned is an important factor when selecting the required filter system, but it is not the only one. The type of material, the web speed, the dust load, the model of the cleaning head and the distance between cleaning head and filter system are equally important. The maximum web width per filter type specified in our overview tables should therefore be regarded as a nominal value. Our experts will always find the right filter for your web cleaning solution.
