Pacific HVAC Engineering Attenuators offer high performance noise reduction in ducted ventilation systems at competitive prices.
Attenuators and pods (where fitted) are rigidly constructed from galvanised steel, internally lined with sound absorbing material not less than 100mm thick, retained by galvanised steel perforated sheet. Attenuator end faces are drilled and tapped to match the flange details of the associated fan. Attenuator ‘sound’ absorbing material is chemically inert, non combustible, non hygroscopic and vermin resistant.
The performance of Pacific HVAC Engineering Attenuators has been determined by testing in accordance with BS4718:1971.
Detailed attenuator selections are available using our fan and noise attenuation software package, FansSelect.
