Oase Combination Filters
Combination filters are essentially the merging of two technologies, rotary drum pre-filters and moving bed biological filters into one combined unit. This saves space, plumbing complexity and the associated costs, and also of course the risks of a mismatch between two differing types of filters which may not work well together. In this way the whole filter becomes an automatic system, with virtually no maintenance required, since drum filters are almost 100% automatic in operation, and moving bed technology has proven to be just about the most efficient form of biological filtration available, being virtually maintenance free and very efficient. The Oase Combination filter range represents the culmination of many years of development in the field, and Oase were the first company to produce rotary drum filters for the Aquatics market. Since then they have developed into one of the world leaders in this field and now offer a wide range of product. They are without doubt the best in terms of build quality and after sale service and warranty support, with all the products in the range offered with a 3 year manufacturers guarantee.
