FEATURES
Marine grade axial fans manufactured under license from Witt & Sohn are available for standard and high pressure applications.
Witt & Sohns well proven expertise has established this product as one of the leaders in Marine fan technology and associated noise and vibration control.
With a standar fan design as the starting point for a given application, using the latest CAD technology the Witt design team can rapidly incorporate any requisite design modifications from standard component elements to accommodate even the most exacting fan specification.
This means that such specification criteria (eg. severity of duty; space limitations; special materials and surface treatments) - can be incorporated efficiently and at considerably less cost and lead time than a conventional one off design approach
