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.
Do not install Silvent products until you have read and understood the Silvent Group General Instructions for use.
The data are based on measurements performed under the following conditions:
For our nozzles and air knives, maximum recommended working pressure is 1.0 MPa (145 psi) unless stated otherwise. For our air blowing guns, maximum recommended working pressure is 0.7 MPa (100 psi) unless stated otherwise.
Cylindrical thread according to ISO 228/1. Use sealing washer, adhesive or thread tape during assembly. Another classification for this thread is BSP (British Standard Pipe Thread).
American Standard in accordance with ANSI/ASME B 1.20.1. Thread deformation achieves a seal.
Metric thread according to ISO 68/ISO 724. Use adhesive or thread tape during assembly.
• Feed pressure is measured at air nozzle air inlet.
• The blowing force is measured on a flat surface of 310 x 290 mm (12.20” x 11.40”) and with a distance of 200 mm (7.87”) from the air nozzle outlet.
• The sound level is measured at a distance of one meter (3.28 ft) from the air nozzle outlet and with the microphone perpendicular to the direction of the air jet.
• The air consumption is measured by a flow meter located immediately before the air nozzle inlet.
All technical data presented in this catalog apply at a feed pressure of 500 kPa (72.5 psi) unless stated otherwise.
The specific figures for noise reduction and energy savings on the product pages are based on replacement of an open pipe with a diameter as indicated for each product in the technical data.
An important factor for the air nozzle(s) to function optimally is that the air supply must be large enough. Otherwise the flow might be turbulent and/or the blowing force could be unevenly distributed. For applications that use many nozzles mounted on a line the air supply can be divided among multiple inlets. It is also important that fittings and nipples do not choke the air supply.
