Aquaculture Filters for RAS & Intensive Fish Farming

Features

• 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.

• Energy-Efficient Drive Systems
  Integrated low-rpm motors with torque limiters prevent overload under sudden debris surges. Optional variable frequency drives (VFD) can be supplied to sync with smart controllers or SCADA systems.

• Backed by Field Deployment in Over 30 Countries
  From bio-secure hatcheries in Norway to high-density carp systems in Eastern Europe, YUTANK filters have been validated in both pilot-scale and industrial aquaculture setups, with tailored models supplied based on climate, stocking density, and water source.

Order Fulfillment

Packaging Standards
All filtration units are protected with multilayer cushioning and moisture-proof sheeting before export. Drum filters and settlers are shipped with pre-assembled core components; rotating parts, pumps, and sensors are packed separately to avoid transit stress. Units exceeding 1.5m³ are reinforced with treated plywood crates and galvanized steel framing, suitable for sea container stacking.

Shipping & Container Loading
YUTANK regularly consolidates RAS orders for overseas hatcheries, optimizing loading plans for 20ft/40ft HQ containers. For example, up to 4 standard-size box drum filters can be loaded in a 20ft container with full protection. We support both FOB and CIF terms, with flexible port options in South China or third-country transshipment for restricted regions.

Lead Time & Production Capacity
Standard lead time is 12–18 working days after deposit confirmation. Bulk orders for filters (≥10 units) may require up to 25 days, subject to material availability. Our in-house CNC cutting and welding teams allow for parallel production of mechanical and biofiltration units, ensuring system-level delivery alignment.

Export Support & Documentation
Each shipment includes:

• Commercial invoice and packing list

• Certificate of origin (Form E or FTA variants available)

• CE declaration and motor test report

• Installation guidance (English version, PDF/digital format)

• Optional: SGS inspection support, Embassy legalization, insurance policies

After-Sales & Assembly
Remote video assistance and exploded drawings are available for overseas installations. OEM units can be labeled with client branding and port-of-origin masking upon request. Spare parts (e.g. mesh screens, float switches) can be included in the crate for convenience.

Custom configurations available for high-volume biofloc systems or integrated nursery grow-out platforms. Engineering drawings and CAD cut-outs provided during quotation phase.

Frequently Asked Questions
Real customer concerns. Clear answers. No fluff.

Q1: Can your filtration systems handle both freshwater and marine aquaculture?
A1:
Yes. All our drum filters and protein skimmers are built with marine-grade PP or HDPE materials, and use 304/316 stainless steel fasteners. Components exposed to saltwater—such as mesh screens and floats—are selected for corrosion resistance. Many of our international clients run mixed-species RAS (e.g., tilapia + grouper) with zero material compatibility issues. We always ask about your salinity level before production.

Q2: How do I size the right drum filter for my fish tank volume?
A2:
We typically calculate based on daily water turnover rate (DTW) and feed input. For example:

• A Box Type Drum Filter 80μm, flow 60–100 m³/h, suits ~50 m³ grow-out tanks.

• For fry systems with high TSS, we recommend tighter mesh (≤60μm) and settling pre-tanks.
  You can send us your system layout and fish density—we’ll propose a matching filter model with real-world reference cases.

Q3: Is onsite assembly complicated?
A3:
Not at all. Most mechanical filters arrive with internal wiring and sensors pre-installed. Only minor connections are needed—power in, water inlet/outlet, and signal line to your PLC (if any). We also provide exploded drawings, and many clients complete installation in under 3 hours. If needed, we can support via WhatsApp video or WeChat.

Q4: Do you offer custom labeling or OEM support?
A4:
Yes. For distributors or branded system integrators, we support:

• Custom logo sticker or laser etching on drum bodies

• English + local language manuals with your brand

• Port-of-origin masking for re-export
  We’ve done this successfully for clients in Turkey, the UAE, and Southeast Asia.

Q5: What’s the typical warranty and spare part cycle?
A5:

• Motor and controller: 1-year warranty (excluding misuse)

• Mesh drum: Typically lasts 1.5–2 years under normal solids load

• Float switches and sensors: Replaceable; we recommend stocking 2–3 per system
  Spare parts are available long-term and ship within 3 business days.
