The AL-KO Eco JET series is equipped with fans on the clean air side that extract air containing dust and swarf to the filter unit. The most powerful units of the DUO version have two fans connected in parallel.

The optimised airflow in the separation chamber removes coarse particles directly, before they reach the filter bags.

The residual dust separated from the filters is automatically removed by the AL-KO OPTI JET® and the removed material is discharged into movable collecting containers placed under the filter.
