Silvent Technology

 

Silvent technology makes it possible to blow with compressed air at a low noise level but without compromising on the high blowing force. Instead of allowing the air to expand through one large hole, it is divided into a number of small holes or slits, which increases the frequency of the sound to levels beyond what the human ear can perceive or be harmed. Through co-ejection of the surrounding still air, the speed difference in the air stream is reduced, which also reduces the noise level.

Another important factor to reduce the noise level is to control the air and create a laminar flow that eliminates the turbulence that usually creates noise when blowing with compressed air.

Silvent is continually developing its patented technology and has introduced a whole new dimension to blowing technology. The effect is achieved by surrounding a core of air traveling at supersonic speed with a protective sheath of air moving parallel to the central air jet. The core stream in the nozzle is generated by a Laval nozzle. The design of the nozzle converts all of the energy stored in the compressed air into kinetic energy without permitting the air jet to expand laterally after it has passed through the nozzle. Because of the protective sheath of air, the surrounding air does not slow down the core stream, which can be used to full effect. The gas flow prevents turbulence, thereby lowering noise levels.

Over the years Silvent has received several international patents for its products which reduce both noise and power consumption when blowing with compressed air.

Tuyau ouvert CONTRE buse de soufflage Silvent

 

Comparez les différences majeures entre les buses de soufflage SILVENT et le soufflage à l’aide d’un tuyau ouvert dans le tableau ci-dessous qui est basé sur une journée de travail de 8 heures et un soufflage 5 jours par semaine, toute l’année. Le coût pour 1 Nm³ à 500 kPa est calculé à 0.016 €. Grâce à des essais d’application pratique, nous avons été en mesure de dresser un tableau qui montre les buses qui accomplissent la même tâche qu’un tuyau ouvert.
