Product Description

Product Description

Customized Automatic Cleaning Fish Farming Water Rotary Drum Air Filter

Customized Automatic Cleaning Fish Farming Water Rotary Drum Air Filter is an outstanding and environmentally friendly filtration equipment in recirculating aquaculture. It is mainly composed of four parts: box component, roller component, backwash component and liquid level automatic control component. The drum assembly consists of a drum frame (can be made of metal or plastic) and screen (stainless steel screen or nylon screen) assembly, the main function is to filter the tiny suspended material in the water (fish poop, residual bait, pulp fibre, The main purpose is to filter the water of small suspended matter (fish poop, bait residues, pulp fibres, sand), algae, water fleas and other plankton.

The drum filter is a static filtration system. As the accumulation of solids in the filter screens reduces the filtration efficiency and causes the water level in the drum to rise, backwash will be triggered, and the solids trapped on the filter screens will be flushed into the waste tray and pushed out.

Machine structure 

Features

When the water containing small suspended matter enters into the drum, the small suspended matter is retained by the stainless steel screen mesh, and the water without suspended matter enters into the artesian pool after filtration. 
 
When the drum of suspended solids accumulated to a certain amount, will cause the water permeability of the screen decreased, resulting in a rise in the water level in the roller Jane, when the water level rises to a set high water level; level automatic control components work, at this time, the backwash pump and the roller Jane reducer at the same time automatically open the work of the backwash pump high-pressure water through the microfilter backwash components of the rotating drum screen high-pressure cleaning, clogging in the roller on the Jane filter screen Suspended matter on the screen of the roller simple screen will flow into the dirt collection tank and then be discharged through the sewage pipe under the high pressure water washing.
 
When the screen is cleaned, the water permeability of the drum screen. Rise, the water level in the drum falls, when the water level barriers to the set low water level, the backwash pump and roller simple reducer will automatically stop working, the microfilter and enter a new round of work cycle.

Heavy-Duty Drum Screens with High Sludge Tolerance
Designed for continuous solid separation in RAS operations, our drum filters use stainless steel mesh ranging from 40 to 100 microns, optimized for removing uneaten feed, feces, and fine suspended particles. Gear-driven rotation ensures stable throughput under variable loading.

Modular Design for Multi-Tank Integration
Units are available in standalone or series-ready configurations, allowing flexible integration into hatchery racks, grow-out ponds, or all-in-one systems. Side inlet and bottom outlet positioning reduces dead zones and maintains laminar flow.

Tool-Free Maintenance Access
All service components—spray bars, nozzles, backwash manifolds—are accessible without special tools. In commercial use cases, this cuts average maintenance downtime by 40% compared to conventional welded units.

Adaptable to Fresh and Marine Systems
All wetted parts are made from anti-corrosive materials (PP/HDPE or 316L stainless steel), with proven durability in both freshwater tilapia systems and seawater shrimp or grouper operations.
