Main fans are usually installed on the surface to make installation, access, maintenance and testing easier. Axial main or auxiliary fans (fixed or variable pitch)Īs with any ventilation system, mining ventilation systems consist of air movers (fans) and an air distribution system.Surface-located radial blade fans for accurate air volume control.We also provide cyclone and venturi scrubbers, ducting and parts and accessories. This should lead to reduced downtimes, lower maintenance and energy expenditures and maximised production.ĬFW is an established leader in the ventilation industry, creating ventilation systems on all scales and designing and producing fans for a wide range of applications. The initial price of the ventilation is thus far from the only consideration.Īchieving maximal ventilation performance cost-effectively and with the necessary flexibility demands a systems approach taking all the components necessary for ventilation into account.
While some airflow and efficiency reduction or excess noise may be tolerated, production losses will occur, and the costs of correcting these problems once they become unacceptable can be very large. Reliability is thus an indispensable requirement of ventilation system design.
The air may also contain high dust, humidity and heat loads. The equipment used and the material being mined produces various toxic gases, including Carbon Monoxide, Methane, and Sulphur Dioxide and Nitrogen Oxides. The availability of ventilation capacity is critical to mining operations, and the costs of inadequate fan performance will inevitably have some effect on mine viability and safety.
