The Heart of the Evaporator Air Path
In a bus AC system, cool air reaches passengers through one component: the evaporator blower. The ZHF2101Z uses a double-wheel centrifugal design that pulls return air through the evaporator core and pushes it evenly across the cabin – the geometry that decides whether the back rows feel the same airflow as the front.
Dual wheels mean balanced loading on a single shaft: less vibration, quieter operation, and a motor that lasts. Rated at 3600 rpm with a 1000 m³/h air volume, it matches the airflow demands of 8–12 m coach evaporator units.
