Model 90 Axial Ventilation Fan for Tunnel & Underground Mine Ventilation

Model 90 Axial Ventilation Fan for Tunnel & Underground Mine Ventilation

The Model 90 Axial Ventilation Fan is a high-performance explosion-proof mining ventilation blower designed for demanding underground mining, tunneling, and industrial ventilation applications. Powered by a 22 kW motor and operating at 1470 RPM, this heavy-duty axial fan delivers high-velocity airflow with a wind speed of 33.2 m/s and an axial thrust of 870 N, ensuring efficient air movement in confined and hazardous environments.

Engineered for continuous operation, the fan provides reliable ventilation for underground tunnels, mines, shafts, and construction projects where safe air circulation is critical. Its explosion-proof design makes it suitable for environments containing combustible dust, methane, or other potentially explosive gases commonly found in mining operations.

The robust construction, high thrust output, and efficient aerodynamic blade design enable effective removal of dust, fumes, heat, and harmful gases while supplying fresh air to underground work areas.
