N.B. Weights reported in the table refer to fans without motor and base.
Construction
They are composed of detacheble box in galvanized sheet steel, double inlet fans with forward-bladed
centrifugal impeller, supports placed outside of the box. Each group is composed of two protections,
one for pulleys and belts and one for supports. An adjustable upright motor support plate achieved a
good tension of belts. Looking CCT to the opposite side there is a possibility of placing the transmission
and motor both left and right. Motors are UNEL MEC IP 55 class F single or duble speed. Performances
composed of airflow from 1500 to 35000 m3/h and static pressure from 100 to 1800 Pa.
