Type TSFB

SECONDARY SILENCERS FOR VAV TERMINAL UNITS

For the reduction of air-regenerated noise from air terminal units Type SFTB and CVFB.

Rectangular secondary silencers for the reduction of air-regenerated noise from air terminal units Types SFTB and CVFB.

  • Absorption material in non-combustible mineral wool with RAL quality mark, biosoluble and hence hygienically safe according to the German TRGS 905 (Technical Rules for Hazardous Substances) and EU directive 97/69/EG
  • Mineral wool faced with glass fibre fabric as protection against erosion due to airflow velocities up to 20 m/s
  • PU foam side lining and polymer splitters for sizes 210, 310 and 410

Application

Application

  • Secondary silencer Type TSFB to reduce the air-regenerated noise from air terminal units
