Vane axial fan silencer
Supplied by
- Pod silencers matched to the casing diameter of a vane axial fan, mounted directly on the inlet or discharge flange. The centre pod aligns with the fan hub so the airway area, and therefore the fan curve, is preserved.
- Used on car park ventilation, tunnel and stairwell pressurisation fans, and on axial fans discharging through a façade near residential neighbours. Because attenuation is needed most at blade passing frequency, the silencer is selected against the fan's own sound power spectrum rather than a generic dB(A) target.
- ASTM E477 (Intertek tested)
- AMCA 300
- AMCA 260
- EN ISO 7235
- ASTM E84
