CrawTec DFC-20-PRO combination drum filter for 20 m³/h with biofiltration

Modern closed-loop water systems (CLS) require reliable water filtration solutions to ensure high clarity and consistent habitat quality for hydrobionts. The CrawTec DFC-20-PRO combination drum filter is a powerful and efficient filtration module that combines mechanical and biological water purification. Thanks to this combination, a deep degree of filtration is achieved without significant energy consumption and complicated maintenance.

Working principle and key features

This filter is designed to automatically remove mechanical impurities and biologically purify water, providing high efficiency with minimal operator involvement. Main functions:

Mechanical filtration: a rotating drum with stainless steel mesh traps solids and prevents them from entering the biofilter.
Automatic flushing: an inbuilt pump (500W) cleans the mesh of dirt, extending the life of the filter and reducing the need for manual maintenance.
Biofiltration: floating bio-loading (100 litres) and filter brushes (10 pcs. 80×15 cm) helps to decompose ammonia and nitrite, improving water quality.
Additional purification elements: the filter сan be supplemented with Japanese mats, which increase the efficiency of biological purification.

Design and advantages

The filter is made of food-grade polypropylene 10 mm thick, which guarantees resistance to aggressive water environment, durability and safety for the inhabitants of the reservoir. Dimensions of the installation (1450×1000×1200 mm) allow easy integration of the filter into the existing system. 

The main advantages of this model are:

• Flow capacity of 20 m³/h - suitable for medium to large aquaculture systems.
• Energy efficiency - 40W gearmotor and 300W compressor ensure stable operation with minimal power consumption.
• All-in-one solution - combines mechanical and biological filtration in one housing.
• Easy integration - inlet and outlet pipes Ø110 mm allow easy connection of the filter to the system.
