Drum filter

💧 Why Use a Drum Filter?
🔹 1. Removes Solid Waste Efficiently

The RDF captures fish waste, uneaten food, and debris as soon as water enters the system — usually down to 50–100 microns

🔹 2. Automatic Self-Cleaning System

Unlike traditional filters that need manual cleaning, a drum filter is fully automatic:  

🔹 3. Water Level Monitoring

As more solids build up on the mesh, water flow through the screen slows down.

🔹 4. Reduces Biofilter Load

By removing physical waste first, the biological filter only needs to handle dissolved toxins (like ammonia and nitrite), not solid debris

🧠 In Short
A Drum Filter requires minimal maintenance — just keep the spray system clean, mesh free from clogging, and mechanical parts moving smoothly.

With regular care, it can run for years without major servicing.
