THE BEST TECHNOLOGY

SOMAX has the best and most complete line of rectangular noise attenuators available in the world, featuring technology developed in cooperation with the largest manufacturers of acoustic control equipment in the United States and Europe.

AIR-WAY VARIABLE

The RAV attenuators have the advantage of being able to meet the various spectra by frequency noise attenuation due to the variation of the spacing of cells and three models of existing cells. This change in the spectrum of noise attenuation allows the selection of the most appropriate model for each case resulted from the emitted noise, the geometry of the system and the desired acoustic condition. Furthermore, the design is done so that the obtained aerodynamic resistance is as lower as possible, making the system more energy efficient.

CONSTRUCTIVE CHARACTERISTICS

The RAV noise attenuators consist of housing, cell structure and aerodynamic "nose" entry in galvanized steel sheet. The filling of the cells absorbing noise is made with EUROLON®.

The RAV attenuators are provided with attachment surface formed by horizontal flanges and vertical side cells. The flanges are indicated for connection to the conduit system with self-tapping screws or rivets.

EUROLON® - SOUND ABSORPTION MEDIA

Sound absorbing cells are filled with EUROLON ®, whose composition a is semi-rigid plate of glass wool with a controlled density, treated with special adhesive, covered with woven fiberglass with thread diameter and specifically designed mesh for obtaining the best acoustic performance, resulting in an inert, non-hygroscopic, not subject to decomposition, inhospitable to insects, pests, fungi and bacteria.

The EUROLON ® has been extensively tested for fire resistance according to Standard BS476 (Fire Test on Building Materials and Structures) Parts 5, 6 and 7, and obtained the following ratings:

BS476 Part 5: "Test for Flammability of Materials" Class ''P''.

BS476 Part 6: "Test for Fire Propagation materials" Index Performance (I) = 9.5P and Sub-index (i) = 5.4.

BS476 Part 7: "Test for Surface Spread of Flame" Class 1.

Consequently, Eurolon® is classified as "Class 0" according to "Building Regulations E15 1976" and the "Lloyds Register of Shipping Certificate" is classified as "material having Low Flame Spread Characteristics" comprising including its use in "Offshore Installations".

APPLICATIONS

The RAV attenuators are suitable for use in the treatment of light industrial and commercial noise, with use in a wide range of projects of high responsibility and quality engineering.

SELECTION

The selection of attenuators RAV is done exclusively through specific software, not being available tables or data for self sizing.
