Description
The sound attenuating grilles provide all the protection that conventional grilles provide (protection against rain, birds, larger insects...). In addition to this, the grilles prevent ingress of outside noises into the building through supply openings and at the same time suppress the noise of the ventilation system at exhaust openings.
