Most of the auxiliary fans in mines are normal tube axial type fan and the maximum possible efficiency of tube axial fan is far less then aerofoil fans.
Considering the above fact at Source Wind fan we are manufacturing airfoil bladed auxiliary ventilation fan which is having very high efficiency.
Source Wind auxiliary mine ventilation fans are a single-stage fan and unlike double stage auxiliary fan in mine, the single-stage fan is much more efficient.
If we consider the same efficiency for single stage and double stage impeller then in double stage case we have to multiply the efficiency of both impeller thus resultant efficiency reduced significantly.
Light in weight as auxiliary ventilation fans operate in small branches of mine thus it is very important to have easy in handling, at Source Wind we made our auxiliary fan very robust yet so simple and handy that it can be handled in any of complicated location
Source Wind auxiliary ventilation is available in various material as –
Anti-static fiber auxiliary ventilation fan for coal mine where aluminum is not allowed.
Aluminum alloy fans.
Steel blade for the environment where aluminum is not allowed and FRP is not sustainable like in case of very high tip speed requirement.
