SOUND ATTENUATORS RANGE AV.1

GENERAL TECHNICAL DATA

The sound attenuators range AV.1 are designed to be built-in ventilation and airconditioning installations, aimed to low (attenuate) the sound levels of such kind of units. The attenuators are splitter type with splitter width a=100 mm.

The sound attenuators are manufactured of:

  • The casing and the metal part of the splitters are made of black steel sheets with powder coating (RAL 6019).

The sound absorbing surfaces of the splitters are made from impregnated glasswool plates.

The sound absorbing plates, that are used here, are manufactured from glasswool, impregnated with thermostable resins, covered with glass net (grid), protecting against erosion at air flow rate up to 18 m/s. They are resistant at air temperatures up to 125 o C and nonflammable according to the Bulgarian State Standard 14451-78.
