Acoustic Louvers - Technical Specifications

Silentec Model PA

Silentec acoustic louvers, model PA, allows for air flow while reducing noise. It can be installed in modules, adjacent or superposed, inside a frame fixed in a building wall or as an external barrier-wall.

(1) Standard models in galvanized steel, 24" wide x 48" height
(2) Available optionally:
      a. Protection grid, 1/2" x 1/2" galvanized wire, installed at inlet or outlet
      b. Protection of acoustic media by fiberglass cloth with or without plastic cover
      c. Stainless instead of galvanized steel
      d. Finishing paint
(3) The Dynamic Insertion Loss (DIL) and the pressure loss in the table assume a velocity of 250 feet       per minute between louvers, at a 70 degree F temperature
