• In ideal conditions where the noise level is significant volume.

• All HVAC system which is requiring sound absorption. Cassette thickness can be produced as 50-100mm.VCIS can be produced as arbitrarily with flange. Cassette surfaced attenuator prevents particles scattered in system with glass wall coated glass tissue. For the increase of the sound absorption, cassette surface coated with 0.6 mm. perforated plate.
