Efficient 360° cleaning and drying using SILVENT doughnut nozzles
Examples of cleaning or drying applications:
- cables or rods after rinsing
- pipes before labelling or packaging
- plastic or rubber profiles in extrusion lines
- tubes covered in oil or coating
Drying a pipe after washing using the doughnut nozzle SILVENT 463 L.
The design of 360° nozzles
SILVENT’s doughnut nozzles are designed to surround the material and deliver a uniform 360° air jet. The nozzles are arranged in inner, outer or double rings depending on application needs. Each nozzle is angled for maximum efficiency and minimal noise. Air is distributed evenly around the opening, including at the split in the ring, where specially angled nozzles ensure consistent coverage.
