Centrifugal fan AT series

ventilationsteelgalvanised steel

Scroll casing with forward curved blades – doublet inlet This kind of fans are specially conceived for mechanical ventilation, at temperatures from 20 °C to +40 °C on S, SC, G2L and SC2 models, or up to 100 °C on AR, TIC, G2C, G2C-C2, G3C, G3C-C2 models. Air performance and sound data have been obtained in a laboratory registered by AMCA for AMCA 210/99 air performance testing and they are within the tolerances allowed by the DIN 24166 standard for Class 2.
