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.

The data are based on measurements performed under the following conditions:
Feed pressure is measured right in front of the air nozzle and is stated in the unit kilopascal [kPa] or pounds per square inch [psi]. Technical data presented in the manual apply at a feed pressure of 500 kPa (72.5 psi) unless stated otherwise.
Blowing force is measured on a scale with a flat surface of 310 x 290 (12.20” x 11.40”) and at a distance of 200 mm (7.87”) from the opening of the air nozzle. Blowing force specified in the unit Newtons [N] or ounces [oz] or pounds [lbs]. 1 lb = 16 oz.
Air consumption is measured by a flow meter located before the blowing nozzle. Consumption is given in the unit Normal cubic meter per hour [NmÑ/h] or standard cubic feet per minute [scfm].
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 sound level is stated in the unit decibel A [dB(A)].
The blowing coverage shows the spread of the air in front of the air nozzle and is stated in millimeters [mm] or inches [“].
The measurement data are stated in millimeters [mm] or inches [“].
Maximum allowable working temperature for the products is stated in degrees Celsius [°C] or degrees Fahrenheit [°F].
Describes the type of technology the nozzle is based on.
Our first generation nozzle with aerodynamic outlet holes. These nozzles enjoy all of our benefits such as high safety. low sound levels and low air consumption.
Our second generation nozzle with aerodynamic outlet slots. These nozzles enjoy all of our benefits such as high safety. low sound levels and low air consumption. They are also available with higher blowing forces.
Our third generation nozzles combining a central de Laval outlet hole and aerodynamic peripheral outlet slots. These nozzles enjoy all of our benefits such as high safety, low sound levels and low air consumption. They are extremely well suited for applications with long blowing distances. They are also available with higher blowing forces and are more energy-efficient than their predecessors.
Our fourth and latest generation nozzles with multiple outlet holes based on de Laval technology. These nozzles enjoy all of our benefits such as low sound levels, low air consumption and safety. They also generate significantly higher blowing force and are more energy-efficient than their predecessors.
1.0 MPa (145 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 Default Pipe Thread).
American standard according to ANSI/ASME B 1.20.1. The threads are deformed to achieve a seal.
Metric thread according to ISO 68/ISO 724. Use adhesive or thread tape during assembly.
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.
