The UVCG-14 radial (centrifugal) fan can be used as part of gas extraction plants to remove methane-air mixtures with a methane concentration from 0 to 100% from the excavation fields of mines through ventilation shafts and boreholes.
Operation is possible under the following atmospheric conditions: temperature of transported mixture from 228° to 323°K, dust content up to 150 mg/m³, density up to 1.2 kg/m³, relative humidity up to 95% (at a temperature of 298°K).
The fan is installed on the mine surface. Fan climatic design is UKhL1. Explosion protection category is Ex.IMb
