ESR-T Insulated Fan Box
Inexpensive acoustic insulated fan boxAlthough this series is fitted with only about 90% sound absorbing material, it attains almost the same noise data as a fully insulated box.
High quality mineral insulation material
The rock wool insulating material used has a high spatial density of 88 kg/m3and absorbs lower frequencies much better. The glass fibre sealed surface prevents the escape of fibres up to 36m/s velocity. Fulfills fire classification A2.
Compact and quiet
The forward curved fan impellers have a high power density and low and subjective pleasant broadband noise.
