The Helios HSDV 400 is designed to reduce noise on the pressure side of roof fans in the VD series. Made from seawater-resistant aluminium, this sound attenuator provides an average noise reduction of 8 dB. It is designed for easy installation directly onto the roof fan and can be retrofitted without requiring any structural modifications, ensuring improved acoustic performance while maintaining durability in challenging environments.
