The unique design features of Dutch Filtration dual vessel filter unit

As a consequence of the feedback of our customers every dual vessel filter unit made by Dutch Filtration has unique design features. Instead of the old fashioned swing-bolt system, the dual vessel filter unit is equipped with Rudi Quick opening closure. This enables much faster and safer exchange of filter elements.

Because of the stainless steel 316 inlet and outlet union there are no corrosion issues and this keeps the fine filtration really clean.
