Filtration of clear coat

Perfect finishes through efficient clear coat filtration

Clear coats serve as the final protective and quality-enhancing layer in modern painting systems. Even the tiniest impurities, such as gel particles, fibers, or other solids can cause visible surface defects.

To ensure the highest coating quality and a trouble-free coating process, the clear coat must be reliably freed of even the finest impurities.

The LENZING ViscoFil automatic backwash filter system ensures consistent coating quality over long operating periods thanks to its unique backwash technology combined with depth filtration.

Maximum paint quality with minimal downtime.

During the manufacturing, storage, and application processes, gel particles and other contaminants can enter the clear coat. These contaminants lead to surface defects such as inclusions, craters, or visible texture irregularities, thereby compromising the final quality of the paint finish.

In addition, frequent filter changes cause production interruptions and increase maintenance costs.

Continuous operation in a closed system.

LENZING ViscoFil continuously removes gel particles and solids from the clear coat.

The automatic backwash ensures a long service life for the filter media and virtually uninterrupted operation.

This leads to sustainable improvements in coating quality, system availability, and process efficiency.
