Sound Absorbing Baffles for Silencers - Alfakel S 102

Description

The S 102 are modular rectangular elements made of two parts precast then assembled.
The sound-absorbing material is made of textile fiber.

 

 


Applications

The Alfakel Series S 102 baffles are designed for absorptive silencers. Because they are modular, these elements can be assembled to reach the desired size of silencer for the specific sound-absorbing needs.
Assembling or stacking together more modules will achieve the acoustic and aerodynamic features desired.


Acoustic and Aerodynamic Properties

The purpose of the Alfakel S 102 modules is to reduce noise propagated through air ducts.
Figure 1 shows the number of parallel baffles needed in relation to the head loss.
Figure 2 shows the values of insertion loss for one or more assembled baffles.

General Properties

Weight: 4 Kg approximately
Standard dimensions: 195 x 500 x 500 mm.
Temperatures: — 40 + 90 °C
Fire reaction: low flammability
Mechanical strength: good
Wear resistance: good

Benefits

  • Easy to assemble absorption silencers
  • Can reduce the size of the silencers in most implementations
  • Sturdy
  • Easily interchangeable

Applications

The Alfakel S 102 baffles can be assembled or stacked and inserted in a metal duct of suitable size for the flow capacity required.
The flanged edges of the duct will allow easy insertion and extraction of the silencer.
If the fluid contains grid or impurity, it is recommended that one side of the silencer be constructed so that it can be easily removed when it is necessary to replace the panels.
The photos below show some of the applications of Alfakel S 102 as absorption type silencers.
