Twin Filter

Description

The Twin Filter is a rainwater filter designed for large roof areas up to 800m². It can be installed in underground chambers (typically 1000mm manholes) or mounted on a frost-protected wall. It is also available pre-installed in chambers for quick and easy on-site installation.

Its steep filter design ensures that dirt is continuously washed into the sewer, while the cleaned water is collected and directed into your storage tank. This system uses proven 3P filtration technology to provide consistent and effective water cleaning.
