Rotative drum filtering microsieve ROTADRUM

Micro filtro de tambor rotativo ROTADRUM

Rotative drum filtering microsieve ROTADRUM


The ROTADRUM micro screen is used for the micro filtration of solids, a very robust, mono block piece of machinery, wiTh a minimum mesh of 10 microns and maximum lOOO microns.

Due to its compact and resistant design this equipment can work without problems during 24 hours/day during long periods of time and without needing any type of maintenance.

The ROTADRUM micro screen can be supplied in the compact version or also for installation in civil works.
