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 air guns make efficient use of compressed air. All Silvent 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.

Air nozzles are commonly used for blowing with compressed air in industry when e.g. cleaning, drying, cooling, sorting and transporting objects.
Few industries are aware of just how much their compressed air actually costs. Producing compressed air is expensive, which means it’s important to use it in the best possible way. Silvent’s air nozzles optimize energy use and enable quiet and efficient blowing with compressed air.
Many manufacturing industries use open pipes for blowing with compressed air. While they often do the job, they are an expensive and inefficient solution. Open pipes usually create a great deal of turbulence when blowing with compressed air, which is extremely energy intensive. Thus to use compressed air in an energy-efficient manner, it’s important to minimize turbulence. This is easily done by installing an air nozzle.
Silvent’s air nozzles for blowing with compressed air are specially designed to optimize energy use and create a uniform, smooth and straight so-called laminar air jet. The design reduces turbulence and gives rise to entrainment, which means the compressed air draws the surrounding air with it. When less energy is wasted producing turbulence, a greater part of the energy input can be used for blowing with compressed air. This makes for more energy-efficient blowing, and the installation of a Silvent air nozzle can reduce energy use by up to 35%.
Blowing with compressed air often leads to high sound levels in industry. One reason for this is the use of open pipes when blowing with compressed air. Open pipes create turbulence that generates high sound levels. Noise and high sound levels are not only harmful for people working nearby the blowing application, but also affect concentration and the overall perception of the work environment. There are therefore many advantages in reducing the sound level in industry. To reduce the sound level when blowing with compressed air, all open pipe should be fitted with air nozzles.
Silvent’s air nozzles reduce the sound level when blowing with compressed air compared to blowing through open pipes. This is due in part to the reduction in noisy turbulence from using Silvent’s air nozzles, and also because of the nozzles’ special design. Silvent’s air nozzles pass the compressed air through small holes and slots, which raises the sound to frequencies beyond what the human ear can perceive. This allows us to make blowing with compressed air both quiet and efficient.
Three things to consider when selecting the right air nozzle
There are many different types of air nozzle specially designed to suit specific industries and applications. It can thus be difficult to identify the air nozzle that is most effective for a particular blowing application. The choice of the right air nozzle should be based on the following three parameters: blowing force, blowing pattern and the material.
The third and last parameter is the choice of material. Material choice is often based on the application’s environment and if there is a risk of mechanical wear on the air nozzle. There are also applications where it’s necessary to avoid scratching the surface of the object, and here the choice is often a ‘soft’ air nozzle. Silvent’s air nozzles are available in many different materials such as stainless steel, zinc, aluminum, PEEK, Zytel and EPDM.

Installing air nozzles
The installation of an air nozzle is important to ensure optimal, efficient blowing force.
For the best results, the distance between the air nozzle and the object should be adjusted so that the entire air jet is made full use of. The correct distance depends on the type of application. For example, for general cleaning applications we often recommend a blowing distance of 200 – 300 mm, while we frequently recommend shorter distances for blowing away oil-based fluids. In addition to distance, the angle at which the air jet meets the object is also important. It’s especially important in applications whose job is to remove fluid.
