LTBM series double volute forward belt drive centrifugal fan is comprised of connected volute and impeller of two sets of double inlet centrifugal fans, with one motor used to drive two sets of impellers through belt drive at the same time. The structure greatly reduces the volume of the whole machine and can obtain a large ventilation volume in a small installation space.
Compared with one volute and one impeller, double type has performance of airflow ×2, speed×(1~1.05), axial power×2.15, noise+3.
