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

IIWhen installing, the filter should always adhere to a vertical position. DRUFI filters use the SYR flange system , so they have no switching size per se. It can be mounted on optional SYR DN 32-50 flanges .

It is recommended to perform maintenance by backwashing every six months at the latest. It is recommended to perform back-flushing even in case of flow reduction due to increased pressure loss. The backflush is started semi-automatically by opening and closing the ball valve. You can set the month of the next backwash on the filter. Full backwash automation can be achieved after purchasing the RSA flushing automation .
