EN 13053 Standard

Ventilation for buildings. Air handling units. Rating and

performance for units, components and sections

• 7.2.8*: Fan location

– Installation of fans in Air Handling Units should be designed inway allowing maintenance of proper pressure conditions in orderto avoid leakages of contaminated air. This is especiallyimportant in case of systems in which migration of solid particlesor gases may occur in energy recovery section. (Leakages if any,should be into the Exhaust air, to avoid contamination)
