The drum filter is constructed of stainless barrel (AISI304 or AISI316). The frame is made from galvanized or stainless steel (AISI304 or AISI316). When used in fresh water, typically a barrel in AISI304 is used and the frame is made of galvanized steel. The drum filter is used to remove suspended material mechanically from the water.
Examples of use of drum filters include:
- Entrances to freshwater fish farms.
- Outflow from freshwater fish farms
- Wastewater treatment plants
- Food industry
- Canals in type 1-3 fish farms

At larger amounts of water, drum filters are built together, to achieve the required capacity. This capacity is for normal water in a fish farm up to 15 mg TSS/l. Together with the drum filter, a bypass system has to be installed, so the drum filter is not overloaded, if a power failure crops up or if the drum filter stops for another reason.
