High air volume portable skid mounted propeller fans operate underground to supply ventilation for mine workers. Fans range from 72” to 144” diameter and are capable of producing from 90,000 CFM to 350,000 CFM each. Above ground, double-width double-inlet centrifugal fans pressurize the mine shafts with fresh dilution air. Booster vaneaxial fans connected to flexible ducts provide ventilation for safety related exhaust and supply air systems.
