Manual-electric high-pressure fan

ERV-2.5 is a high-pressure manual-electric ventilation unit designed for supply and exhaust systems in shelters, radiation-protected rooms, engineering chambers, and technical facilities. The fan can operate from the electrical grid or via manual drive, ensuring reliable airflow even during power outages — a critical requirement for protective shelters.

The ERV-2.5 is suitable for ventilating shafts, wells, and engineering structures, and can also be installed in systems with parallel operation of multiple fans to increase total capacity.

The fan assembly consists of:

• the main fan unit;

• a gearbox with manual handle;

• an electric motor with IP54 protection class.

A left-rotating impeller with backward-curved blades provides high efficiency and low noise levels. The housing is made of carbon steel with durable powder coating RAL 7016.

Operating air temperature range: –20°C to +40°C.
