Drum filter HEX

Clean water thanks to bacteria Our biofilter BioKa 600 is a high-performance biofilter. With the enormous surface area of our trickling filter, the BioKa 600 reaches degradation rates of up to 1 kg feed per day through optimal ventilation with the NewBubble aeration system. It removes the fish- toxic nitrogen compounds ammonium and nitrite. Several filter modules can easily be connected for higher capacity The BioKa 600 is ideal for aquaculture, aquariums, and fish ponds. Click here for technical details.
Filter with fleece Fleece filters, also known as paper or nonwoven filters, retain even very small particles (down to 40 microns). Algae, fish excrement, and sludge particles are reliably removed, guaranteeing crystal-clear water. Our fleece filter is particularly suitable for fish ponds and, in some cases, aquariums. The chamber below the fleece contains a fully functional biofilter. This means that the filter removes particles as well as fish-toxic nitrite and ammonia. Our fleece filters are available in 3 sizes. More details.
Drum filter BaseDrum - the all-rounder This drum filter is robust, reliable, and equally suitable for use in aquaculture, ponds, or aquariums. Standard mesh size is 60 µm. It reliably removes dirt, fish excrement, algae, etc. We have been producing the BaseDrum for 5 years now, and our customers especially appreciate its low maintenance and very quiet operation. Find the technical details here.
HEX - the next-generation drum filter The HEX drum filter series sets a new standard for drum filter technology. Equipped with the patented HEX® BeeCell filter plates, they are more efficient than standard filters in removing particulate material from effluent water. HEX technology proves particularly useful in filtering large quantities of water. In addition, the HEX is very economical when it comes to water and energy consumption. The HEX is available in 4 variants and in many different sizes. More details about the benefits of the HEX drum filter and the technical details are available here.
