EHD-FAN SECTION 18/18

The Fresh Air EHD 18/18 is a high-capacity belt-driven centrifugal blower specifically designed for large-scale ventilation and exhaust systems.
It provides very high airflow and static pressure, making it ideal for factories, warehouses, industrial plants, paint booths, and air-handling units.

Engineered for durability, stability, and efficiency, the EHD 18/18 ensures continuous-duty operation, low vibration, and quiet performance even in demanding environments.
