Ventilation Systems For Underground Mines And Quarries
MAIN VENTILATION
Main fans for the main ventilation system designed and installed taking into account the ventilation requirements related to the mining methods and design of the mine. Our software enables us to analyse the impact of ventilation on the meshed networks and to optimise the equipment to ensure performance and energy savings.
Ventilation Systems For Underground Mines And Quarries
SECONDARY / AUXILIARY VENTILATION
Secondary fans allow the air flow to be brought and controlled to the work area. SUB’ROCA designs its secondary fans on general principles of robustness, mobility and performance. Together with you, we define the necessary flow rates and the most strategic duct diameters to ensure reduced energy consumption.

FAQ
Q : we have no data about air quantity of the fan,can you give us some recommendations?
A: Yes,just let us know the tunnel diameter/length,our engineer will design for you.
Q : we want ventilation fans for our coal mine,is there anything we should pay attention to?
A: if use fans in coal mine (especially underground),explosion-proof motor and aluminum alloy impeller is necessary.
Q : what's the meaning of double stage fan?And what is the advantages?
A: double stage fan,means two sets fan used in series. Advantages:larger pressure,long air deliver distance,but fan will be more compact.
