For auxiliary underground ventilation and for mining and drilling of tunnels, CIRIGLIANO manufactures two-stage counter rotating and single-stage axial fans. Its compact design occupies little space and allows its direct coupling to the duct. It is directly coupled to the tunnel wall.
Single-stage and two-stage fans face a wide range of pressures. Operating features are equal to those of ordinary axial fans.
Harmful gases inside the mine are extracted through a chimney.
Fresh air is injected through a chimney and is ejected by the entrance ramp.
Main fans are used to move the air required inside the mine. Equipments are robust and large-sized which move flows from 100,000m³ / h to 750.000m³ / h, usually at low RPM.
Auxiliary fans provide air inside the mine in remote areas. These fans are used to inject or extract air. Reduced in size. Easy maneuverability with flows from 10.000m³ /h to 100,000m³/h and pressures up to 1000mm CA.
