1.0 TRIO 320 is a basic cleanroom cleaning trolley with wringer. It has a stainless steel frame, three 18 liters plastic buckets at the front and two additional plastic buckets at the rear, where cleaning utensils can be safely stowed away. The PurMop® wringer has been developed for use in cleanrooms and is made of polished stainless steel. The innovative function of the wringer enables improved reproducibility by means of a defined wringing pressure and reduced user effort thanks to the force transmission mechanism.
