Our air nozzles, air knives and safety air guns are designed to reduce sound levels and improve the efficiency of blowing with compressed air.
Blowing with compressed air is common in industry when cleaning, drying, cooling, sorting or transporting objects. Silvent air nozzles are used in fixed installations and make efficient use of compressed air. All Silvent air nozzles feature the optimal combination of high blowing force, low energy consumption and low noise levels.
Air knives are most commonly used to blow away liquids, grime, airborne debris, etc. from surfaces or objects. Silvent air knives create a broad and effective flow of air that produces a pneumatic scraping effect without mechanical contact. All Silvent air knives feature the optimal combination of high blowing force, low energy consumption and low noise levels.
Manual blowing with compressed air is common in industry when cleaning, drying or cooling objects. Silvent safety air guns make efficient use of compressed air. All Silvent safety air guns feature the optimal combination of high blowing force, low energy consumption and low noise levels, at the same time as they are ergonomically designed for professional use.
The noise from compressed air valves is extremely hazardous, but equipping valve discharge ports with pneumatic mufflers often causes operational disturbances. Silvent pneumatic mufflers have integrated warning indicators. The technology basically entails that the pneumatic muffler itself sets the optimal combination of flow capacity and noise suppression thanks to the dynamic internal filter, which subsequently minimizes operational disturbances and eliminates clogging.

To optimize blowing, it is sometimes necessary to be able to make pressure or blowing angle adjustments, for example. In other cases protection against airborne debris may be needed. Silvent has different types of accessories for easily performing various blowing tasks, optimally and safely.
Silvent technology – a revolution in pneumatics
Silvent’s patented blowing technology, known as Silvent technology, utilizes engineered laminar air jets to minimize air turbulence usually caused when blowing with compressed air.
The design and shape of the nozzle also means that some of the air surrounding it is drawn with relatively little resistance into the air jet providing a greater blowing effect. Thus, the reduced turbulence, higher frequency and co-ejection of the surrounding air lead to a reduction in sound level and energy input while providing energy-efficient blowing force. Every part of a Silvent air nozzle is designed to optimize the combination of blowing force, energy consumption and noise levels.
” The design, location and discharge angles of Laval nozzles are intended to optimize the conversion of the compressed air’s potential energy into directed, concentrated kinetic energy.”
The Silvent technology
1. Silvent’s first patent was based on air flowing and expanding through multiple aerodynamic holes generating parallel air streams, creating laminar jets. This has formed the basis for all further development of the Silvent technology. The next development step was to replace the holes with slots. This allowed greater discharge areas to be achieved and thus higher blowing forces. By using the aerodynamic holes, the laminar jets and low sound levels could be maintained, as could the efficient use of compressed air.
2. Since then, Silvent has patented many technologies including one based on a combination of existing Silvent patents. This technology incorporates a central Laval nozzle creating a supersonic jet at the core, flowing parallel to peripheral jets. The compressed air’s entire energy is transferred into kinetic energy without the core jet expanding sideways. The peripheral jets prevent the core jet from being impeded by the surrounding air, allowing it to be used to full effect and at greater blowing distances.
3. In terms of manufacturing, Silvent’s latest generation of patented air nozzles are complicated products that not only include a central Laval nozzle, but also where the entire discharge series is based on Laval technology. Each Laval nozzle works together with the others. The design, location and discharge angles of Laval nozzles are intended to optimize the conversion of the compressed air’s potential energy into directed, concentrated kinetic energy. (Figure 3) This results in a unique combination of fully utilized compressed air and the lowest possible sound level.
Today, Silvent has a number of safety air guns – Pro One, Pro One+ and 767-L – that are equipped with the new generation patented air nozzles. The safety air guns have characteristics that would have been impossible to provide just a few years ago. In order for the work to be as efficient as possible, all research, development and product development at Silvent takes place in close collaboration with key customers.
