Alfa Laval AVNX-4055 Solid Bowl Decanter Centrifuge. Used.

📄 Product Description

This Used Alfa Laval AVNX 4055 Solid Bowl Decanter Centrifuge is a high-performance, continuous separation system designed for wastewater treatment and solids recovery in industrial food processing environments. Built with 316 stainless steel product contact surfaces, it is corrosion-resistant and sanitary enough for meat and poultry processing byproducts.

The unit features a maximum bowl speed of 3250 RPM, a 20° beach angle, and a single lead conveyor designed for optimal solids transport. It includes a single row of lined cake discharge ports, integrated gearbox and feed pipe, and is powered by an approx. 55 kW main drive motor with back drive for rotational differential control. A control panel is also included, and the unit is mounted on a stable 4-leg frame. Weighing approximately 2 tonnes, this centrifuge is robust and well-suited for high-throughput operations.
