SILVENT 475 L: with its double nozzle ring, is entirely unique. Two different blowing patterns unite to achieve maximum results. The outer ring provides initial cleaning and prepares the surfaces for the inner system, which then completes the drying or cleaning process. The system is designed to clean or dry cables, pipes, sections, hoses, etc. that require extra high blowing force or pass through the doughnut at high speed. Efficient and uniform 360° coverage is guaranteed - even at the opening in the doughnut, where extra powerful nozzles are mounted at the optimal blowing angle. SILVENT 475 L allows problem-free insertion and removal of material with diameters of 100 to 205 mm (4” – 8.1”) through the opening in the doughnut. It features robust attachment lugs for easy and safe mounting.

Drying a pipe after washing using the doughnut nozzle SILVENT 463 L.
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.
