Doughnut nozzles

Fully meets the EU Machine Directive’s noise limitation requirements and OSHA’s safety regulations.

SILVENT 453: the smallest version of Silvent’s doughnut nozzles with just an inner ring of nozzles. This is our most commonly used type of doughnut nozzle. Finding the blowing pattern that is most suitable for the majority of blow-off processes is the result of years of experience with previous generations of doughnut nozzles. These nozzles are designed for continuous production and the cleaning or drying of cables, sections, pipes, hoses etc. The SILVENT 453 allows problem-free insertion and removal of material with diameters of 5 mm to 25 mm (0.2”-1.0”). There are attachment lugs for easy and safe mounting.

Fully meets the EU Machine Directive’s noise limitation requirements and OSHA’s safety regulations.

SILVENT 464: a doughnut nozzle with just an outer ring of flat nozzles that offers the very lowest noise level and air consumption. Perfectly adequate for the removal of lightweight matter and lesser amounts of liquid. Provides plenty of blowing force for applications such as drying or cleaning of cable, pipe, hose or sections passing through the doughnut at moderate speeds. 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 464 allows problem-free insertion and removal of material with diameters of 25 to 105 mm (1.0” – 4.1”) through the opening in the doughnut. There are attachment lugs for easy and safe mounting.

Fully meets the EU Machine Directive’s noise limitation requirements and OSHA’s safety regulations.

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. Fully complies with the noise limitations of the EU Machine Directive and OSHA safety standards. Patented.
