A lot of moving parts which are sensitive to malfunction ® water – therefore debris IN-TA-CT and wear-out disposal is no issue 2. The spray water system as cleaning device is susceptible Unique backwash technology to blockage – it requires good spray water quality by air burst of patented fish friendly polyhedra 3. All collected debris must be disposed of No moving parts under water Postal address: B: Functional issue - no clear debris barrier
