Direct drive screeners, because of the hammering action of transversal rods against the screen deck tend to be slowly substituted by more modern systems.

The constant action of the rods against the screen makes the screen cloth lifetime to be severely reduced and more: noise is a permanent problem because the abatement measures which include total enclosing make these screeners expensive machines.

Mavi has built them for many years, since 1979, but the modern screeners have actually replaced these units and nowadays only some units in noise independet prodution facilities have been sold.

Maybe it is farewell time for these noisy fellows.
