Mines, tunnels and quarries require fans and blowers for ventilation or exhaust gas systems. High pressure axial fans blow air into ducts, tunnels and underground passages. In mining ventilation systems axial fans may be applied to exhaust or in discharge configuration and proper technology may be used to satisfy required specifications.
Moreover, centrifugal and axial fans may be applied as main or optional machineries for many consequent processes and applications, such as digging tunnels and drilling, to convey the extracted material or residual matter, for pneumatic conveying, crushing and subsequent processing.
Mine fans require heavy-duty design with welded flanges to ensure reliability, resistance and long life in the harshest environments and severe conditions. Specific painting process, galvanic finishing or inox steel and corrosion resistant materials will protect the fan against corrosive gas and atmosphere. Correct impeller balancing, welded flange connections and dampers minimize vibrations, whereas high efficiency silencers reduce noise level. High energy efficiency is also required to reduce consumptions.
To increase air pressure, we can supply multi-impeller axial fans or configurations, made of two or more fans mounted in series. Centrifugal fans may be used for mining and tunneling applications and for special purpose tunnels, ducts, pipes and channels.
Heavy-duty design and construction, proper materials with considerable thickness, suitable for harsh environments and corrosive atmospheres.
Explosive gas or dusts may be found in galleries. Process plants may be classified as hazardous areas. Explosion-proof or anti-sparkling construction.
