The filter is made from very high-quality thermoplastic resistant to mechanical damage and falls. The rubber parts are made from elastomer. The metal components of the filter are made from red bronze alloy or stainless steel.

When installing, the filter should always maintain a vertical position. DRUFI filters use the SYR flange system, so they do not have any inherent connection size. They can be mounted on purchasable SYR flanges DN 20-32.

Maintenance is recommended every six months at the latest using backwashing. Backwashing is also recommended if there is a reduction in flow due to increased pressure loss. Backwashing is initiated semi-automatically by opening and closing the ball valve. You can set the month for the next backwash on the filter. Full automation of backwashing can be achieved by purchasing the RSA flushing automation.
