2. APPLICATION AND DESIGN
The 14-size product line is designed for air handling processes in range of capacity from 1200 m3/h
to 100 000 m3/h - in case of remaining AHUs. The VENTUS air-handling units are designed for a
ventilation system where an access to the rotating parts of the unit (a fan’s rotor) is feasible neither
from the overpressure nor sub atmospheric pressure side of the unit. The ventilation system is
understood as ventilating ducts as well as e.g.: air intake and air exhaust modules in case of the units
installed outdoor.
