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.
The calculations are based on the following table with measured figures for the pipe dimensions and Silvent’s air nozzles. The cost savings in the table are calculated assuming the cost of compressed air is 2,1 cents (EUR) per Nm3/h and the blowing time is 2 hours per day.
In the example below, we assume you have a Ø 6 mm open pipe, the compressed air costs 2,1 cents (EUR) per Nm3/h, and that you have a blowing time of 2 hours per day.
Blowing time per year: 52 weeks x 5 days x X hours/day 52 weeks x 5 days x 2 hours/day = 520 hours/year
Saved Nm3 per year: Air savings Nm3/h x blowing time 37 Nm3/h x 520 h = 19 240 Nm3/year
Saved EUR per year:
Air savings Nm3/h x compressed air cost x blowing time 37 Nm3/h x 0,021 (EUR) x 520 h = 404 EUR/year
Sound level reduction dB(A): Sound level open pipe – sound level air nozzle 102 dB(A) – 80 dB(A) = 22 dB(A) sound level reduction
