Our air nozzles, air knives and air blow 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 blow guns make efficient use of compressed air. All Silvent air blow 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.
Some industries and processes need more blowing force than a regular air blow gun can generate. Therefore, Silvent has developed air blow guns with high blowing force. The blowing force ranges from twice as strong up to 30 times stronger than a regular air blow gun. All Silvent air blow guns are safe, quiet and efficient, and are developed 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.
Most industries use compressed air to clean during the production process or to clean the working station. Air blow guns are often used, especially when cleaning workbenches or floors, but in many cases air nozzles or air knives can be much more effective when it comes to repeated blowing. Today, many companies are trying to automate all manual blowing. When installing an air nozzle or air knife, it is often possible to get consistent and qualitative results.
The air nozzle SILVENT 9002W is cleaning the rubber strip from chips. The nozzle is mounted on a bendable Flexblow hose that makes it easy to fine-tune the blowing angle, for optimal cleaning.
The mold is effectively cleaned with the air knife SILVENT 300, which is adapted to the dimensions of the mold. It is often most effective to install a customized solution when it comes to complex processes. SILVENT 300 is adapted to the application’s needs and challenges.

To achieve good results when painting MDF boards, the surface must be completely free from sawdust and debris. The company’s existing solution consisted of its own air knife and air nozzle designs, but it lacked knowledge about how to design efficient air knives. Thus, the existing solution meant e.g. high sound levels in violation of the company’s policy, as it was actively engaged in reducing noise levels in production.
The custom SILVENT 300 air knife was designed by Silvent engineers, who through their broad experience and expertise, are able to provide efficient blowing with compressed air. For maximum sound level reduction, it was necessary to adjust the blowing force, blowing pattern, blowing distance and blowing angle based on the unique application. It was also possible to adjust the supply pressure after installation, which meant additional savings.
A custom air knife from Silvent was installed to reduce the high sound levels and optimize the use of compressed air. This also meant the supply pressure could be reduced significantly. Measurements carried out before and after the installation showed that noise levels were reduced by 10 dB(A), which the ear perceives as a halving of the sound level. The installation also led to energy savings of 25%.
Industry: Steel and metalworking
An emulsion is applied for cooling and lubrication when cold rolling steel. If this emulsion is not removed after rolling, it can cause problems such as streaks, stains and rust on the surface of the steel. The company’s existing solution failed to remove the emulsion satisfactorily. This affected the surface finish and led to deviations that were difficult to remedy afterwards. The deviations led to an increasing number of rejects, more material consumption and greater costs for the company.
The Silvent AirPlow is specially designed to improve quality in the steel and aluminum industries. The high velocity of the steel sheet and the amount of emulsion means that the shape of the blow-off equipment is crucial for results. To provide the best possible results, Silvent’s engineers make sure that all AirPlows are optimized to each application. The AirPlow also reduced overall energy consumption compared to the earlier solution.
The installation of a SILVENT AirPlow resulted in a significant improvement in the surface finish of the steel sheet. Blowing-off the steel with compressed air directly after rolling is a common method for achieving a clean, dry surface. The plow shaped blow-off was more successful in removing the emulsion from the center of the steel sheet all the way out to the edges. The amount of rejected material was reduced and all of the steel produced could be sent to the galvanizing process.
