The fan is designed to convey non-explosive gas mixtures, aggressiveness of which in relation to the carbon steel is not higher than the aggressiveness of the air
The VO fans are designed to provide main ventilation of tunnels and metro stations and operate as components of ventilation systems of enterprises in other industries, used for the movement of air and non-agressive gases (the aggressiveness of which in relation to carbon steel is not higher than the aggressiveness of the air, containing no sticky substances, fibrous materials with a content of dust and other solid impurities not more than 10 mg/m3.)
Fans can be equipped with an automatic control system.

Operation
Climatic design U (moderate climate), placement category 3 according to GOST 15150. Used to ventilate for 1 hour at 400 °C in the emergency mode. Also used in smoke ventilation systems to remove products of combustion in case of fire. Designed for operation in atmospheric conditions at conveyed air temperatures of 228 to 323 K and relative humidity up to 98% (at 298 K).
