Why Silvent?

Three good reasons why you should use Silvent’s products for blowing with compressed air:

  • 50% Lower sound level*
  • 35% less energy consumption*
  • Reduced risk of injury*

*Compared to an open pipe.

 

This is possible thanks to Silvent technology, which reduces turbulence and creates a more uniform, smooth and straight air jet when blowing with compressed air, which is sometimes referred to as a laminar air jet.

 

1. Reduced noise level

Blowing with compressed air can generate high sound levels, which can harm operators. To combat this, Silvent’s safety air guns, air nozzles and air knives are designed to reduce sound levels when blowing with compressed air. The products reduce turbulence, which enables a reduction in noise levels. The specially designed air nozzles also help reduce sound levels, as they pass the air through multiple, uniquely designed holes or slots. If the air jet is led through multiple small holes instead of one big hole, some of the sound is raised to frequencies that are beyond what the human ear can perceive or be harmed by.

 

2. Reduced risk of occupational injuries

When blowing with compressed air, it’s important to be aware of the risks. Young people are overrepresented in accident statistics, which is often due to a lack of training in the use of compressed air. Silvent’s air nozzles have a special design that prevent the nozzle orifice from being blocked by the operator by mistake. Totally blocking the orifice could cause the operator serious injury. If the pressure is too high, which can be the case in total blocking, the compressed air can penetrate the operator’s skin. This can lead to serious injury such as air embolisms and cerebral hemorrhage. Silvent technology minimizes the risk of this type of injury and meets government safety requirements.

 

3. Reduced energy consumption

Few people are aware of just how much compressed air actually costs. To reduce energy consumption, it’s important to reduce the turbulence that occurs when blowing with compressed air. Because less energy is wasted producing turbulence, a greater amount of the energy input can be used for blowing with compressed air. This makes for more efficient blowing. Silvent technology also increases air entrainment, which means the compressed air draws the surrounding air with it. In this way, the same output is achieved for less energy.

Everyone has the right to a good working environment

Blowing with compressed air

Safety air guns can be found everywhere in any production facility and they are the product that most often springs to mind when talking about blowing with compressed air. Safety air guns are used primarily for cleaning tools, machinery and parts as well as floors and entire workplaces etc.

 

Blowing with compressed air is used for:

  • Blowing clean
  • Drying
  • Cooling
  • Sorting
  • Transporting

 

A conventional open pipe with a drilled hole or nozzle suitable for fluids is commonly used in such applications. Technical design calculations are seldom carried out, which in principle means that every application is over-dimensioned.

The use of compressed air in industry

“Blowing with compressed air stands for 50% of all compressed air consumption”

 

Blowing: 50%

Actuators: 20%

Leaks: 15%

Other: 10%

Tools: 5%

Replacing open pipes with air nozzles for compressed air

The open pipe:

  • Used worldwide in the manufacturing industry for blowing with compressed air
  • Available in various sizes and materials
  • No technical documentation whatsoever

 

Using an open pipe for blowing often works, but there are disadvantages:

  • Generates high levels of harmful noise, due to the turbulence created
  • Hugely energy intensive, which means operating costs are extremely high
  • Can cause severe injury such as air embolisms

 

Most installations with open pipes are not based on any previous technical design calculations, which means that 90% of them are inefficient and over dimensioned. With our products and know-how, we are able to replace open pipe installations and achieve huge benefits.
