Cross-Talk Silencers

For use between rooms, such as office areas, to maintain the partitioning acoustic integrity while allowing circulation of ventilation air between the areas. VG Engineering provides cross-talk silencers that give excellent sound attenuation and air flow in both directions, in “L”, “Z”, and “U” configurations. Acoustic media options include wrapped fiber and fibreless configurations to suit customer needs.

Acoustic Louvers

VG Engineering provides acoustic louvers for the ventilation of mechanical enclosures, rooms and areas while attenuating the sound of the equipment to acceptable levels. Louvers provide a line of sight block and are available in a range of sizes; configured to prevent water ingress and provide a low pressure drop. Our acoustic louvers provide a long and trouble-free life and include bird screens or insect screens and in finishes to suit the architectural requirements. Standard construction is in galvanized steel, stainless steel and aluminum. Louvers can be mounted in most types of wall including concrete, block and metal panel, as well as barrier walls.
Typical uses include:

Generator Enclosures
Compressor Enclosures
HVAC equipment enclosures
Chiller Plant Areas
Cooling Towers
