DUO 300 is the larger version of our stainless steel cleaning trolleys with wringer. It has two stainless steel buckets with a capacity of 8.5 liters each and a stainless steel bucket with a capacity of 26 liters at the front. The PurMop® wringer has been developed for use in cleanrooms and is made of polished stainless steel. The innovative functional principle of the wringer enables improved reproducibility by means of the defined contact pressure and reduced force thanks to the power transmission mechanism.
