Ventus Air Handling Units
Fig.3. Example of the basic supply-exhaust unit: 1 – bag filters, 2- counter-flow heat
exchanger, 3 - droplet eliminator, 4 – coil, 5 - direct driven fans, 6 – casing
Majority of AHU-s configuration is available in left-hand (LH) and right-hand (RH) version (fig. 3 and
4). The version of the unit is determined by the flow direction of the air against the tending side of the
unit (the side where the inspection panels are located). In case of supply-exhaust units the version is
determined by the flow direction of the air in the supply section.
