Designed to ventilate tunnels and underground stations. The fan is installed on-site in a tunnel chamber and can be used in single-fan / dual-fan installations.
The VOM-20 axial-flow fan is designed to ventilate tunnels and underground stations. The fan is installed on-site in a tunnel chamber and can be used in single-fan / dual-fan installations. The airflow is reversed by changing the rotation direction of the electric drive motor.
— The fan can be equipped with an automatic control system
Features
With the VOM-20 fan, a series of modern fans with the impeller located directly on the shaft of the electric motor was launched.
The fan design allows disassembling up to vertical and horizontal flanges, enabling transportation and installation in the confined area of operating underground systems. Later, this option was implemented in the state-of-the-art VOM fans of sizes 16, 18, and 24 (designated as "P")
This horizontal fan is mounted on a frame and with an electric motor on the same shaft.
— Designed for operation at atmospheric temperatures from -45 °C to +50 °C and relative humidity up to 98%.
— To be installed on-site in a ventilating chamber.
— Used for ventilation in emergency mode at a temperature of 300 °C for 1 hour.
— To be used in single-fan / dual-fan installations.
