Drum filter for pond or RAS 75 m³ - reliable filtration for fish farming and aquaculture

The 75 m³ drum filter for fish farming and aquaculture is a powerful solution for large-scale water treatment systems.

In closed-circuit water plants (CCW) for intensive fish, shrimp and crayfish farming, water quality determines the success of the entire production. The CrawTec drum filter for systems up to 75 m³ is a highly efficient device that provides mechanical, unattended cleaning of suspended solids and organic contaminants.

How does a drum filter work?

The filter passes water through a 63 micron mesh stainless steel screen, trapping the smallest contaminants. As sludge builds up, an automatic system starts the washing process - the drum rotates and the inbuilt pump flushes the accumulated particles down the drain. This allows the filter to run continuously, keeping the water in the tank crystal clear.

Main advantages and technical features

• Flow capacity up to 75 m³, making the filter optimal for medium to large farms.
• Robust 10 mm thick food-grade polypropylene housing is resistant to water, chemicals and UV light.
• Compact dimensions (900×900×1000 mm) with high capacity.
• 4 inlet and 4 outlet connections (110 mm) for even distribution of water flow.
• The 63 µm stainless mesh traps even the smallest mechanical impurities.
• Automatics with level sensors control the filter operation without operator intervention.
• Flushing pump included - reliable cleaning of the filter surface.
• Powerful 120 W gear motor ensures smooth drum rotation with minimal power consumption.

Where is the 75 m³ drum filter used?

1. In medium to high capacity closed-circuit water systems (CCWS);
2. In large fish farms for sturgeon, carp, prawns and Australian crayfish;
3. In industrial and ornamental ponds requiring a high degree of filtration;
4. In aquatic systems where it is important to maintain stable water purity.

Minimum maintenance - maximum efficiency
The drum filter is fully automated and requires minimal maintenance. The operator only needs to periodically check the condition of the system and, if necessary, clean the drain.

Customised filters

This model is one of our standard designs. If you require a different filter capacity or size, we can custom design a filter for you. CrawTec designs and manufactures drum filters for all sizes, from small farms to industrial complexes.
