VOD-18 FAN

The VOD-18 axial fan is designed for main ventilation of coal and ore mines, as well as ventilation systems of plants in other industries, which are used to ventilate air and non-aggressive gases.

VOD-18 fan application
The VOD-18 axial fan is designed for main ventilation of coal and ore mines, as well as ventilation systems of plants in other industries, which are used to ventilate air and non-aggressive gases.

The airflow is reversed by changing the rotation direction of the electric drive motor while simultaneously changing the setting angle of the both guide vane and straightener blades. Reversing provides 60-70% of the air supply for direct operation without the use of bypass ducts.

The fans can be used for both suction and discharge ventilation systems.


Can be equipped with automatic control systems

VOD-18 fan design

The VOD-18 fan consists of a housing with guiding vane and straightener, a rotor, a transmission shaft, a spinner, a manifold, a brake, a diffuser, an anti-stall device and an electric drive motor.

The housing has a horizontal connector.


The rotor bearings are mounted on the housing supports.
The simultaneous rotation of the blades is performed by an electric drive via a chain drive.


Impeller blades are fixed on steel hub wheels by spring rings, which allows turning them at any angle from 15 to 45C using hatches, to regulate supply and pressure when the fan is stopped.


The rotor rotates in rolling bearings. The bearing grease is thick and replenished through remote grease nipples.


The transmission shaft is suspended and connects the drive motor to the rotor by gear couplings.


The fan is equipped with an electrically operated pad brake.


The fan is equipped with a device for measuring the flow and pressure. It consists of a pressure receiver and a set of control and measuring equipment.
