PTO fans are structurally manufactured: ensuring the possibility of reversing the air flow at least 70%; ensuring the possibility of reversing the air flow at least 100%. The air flow is reversed by changing the direction of rotation of the drive motor shaft.
Axial fans PTO are designed to ventilate tunnels and metro stations, as well as to work in ventilation systems of enterprises in other industries. The fans are designed for a long period of operation at a temperature of transported air from -30 to +45 C and relative humidity up to 98%. If necessary, fans can be used to move a gas-vapor-air environment with a temperature of up to +250 C for 120 minutes.
