Velda Replacement UV-C Unit

All Velda filters include a special building-in UV-C Unit. Separate units can be used for the Clear Control pressure filters, Cross-Flow Biofill and Giant Biofill XL. Its action is based on ultraviolet radiation, which attacks cells of green floating algae and germs. With the help of this UV-C Unit you will obtain crystal clear pond water in a short period of time and a healthy environment for fish and water plants. The UV-C Unit has been equipped with special 'long life' UV-C lamps.

The UV-C Unit can be mounted in the Cross-Flow Biofill, the Giant Biofill XL and the Clear Control Pressure Filter. The advantage of the unit is that all floating algae and any germs will be killed before the water is passed through the filter materials. You will obtain crystal clear pond water in a short period of time and a healthy environment for fish and water plants.

The 'long life' UV-C lamps, which are supplied along, have a lifetime of over 7000 burning hours.
