Silencer Round Standard
LUFT sound attenuators, the brand leader in the air movement industry, present the all new
circular design which incorporates modern technology keeping pace with continued
development and change. lnitially intended for use with axial flow fans these circular modules
have many unique features which ensure LUFT maintains ifs brand leader status and
there is no limit to the number of applications for which these highly versatile circular sound
absorbers may be used.
Manufactured in standard metric diameters from 315mm to 1250mm with flanges drilled to
match the LCA range of axial flow fans.
Two types are available, the straight through design with negligible pressure loss and the podded with centrally mounted aerodynamic absorbent pod with increased attenuation but additional pressure loss.
The are three length sizes available for each silencer. These are 1.0D where the length is equal to the diameter, 1.5D where the length is one and a half times the diameter and 2.0D which is twice the diameter of the fan / attenuator.
