CFT/Korfmann main mine fans operate both on the surface and underground as single or multiple units in series or as a block. In this respect, they create intelligent, bespoke solutions for energy efficient main mine fan stations that are characterised by features such as mechanical blade adjustment during operation, variable frequency drives, etc.
Either axial or centrifugal fans for ventilation can be offered complete with silencers and other accessories as required for the specific conditions of your project. The axial fans from 300 mm to over 4500 mm impeller diameter come from the CFH subsidiary Korfmann Lufttechnik GmbH.
Every fan is thoroughly tested at our in-house fan testing facilities before leaving the factory. Certificates of conformity to national and international standards are available.
A multitude of applications for axial fans:
main mine fans
portal fans
booster fans
fans as part of a system (dedusting, heating, cooling, etc.)
auxiliary fans
flushing fans
tunnel jet fans
smoke exhaust fans
Jet fans and smoke extraction fans for safety in road, metro and railway tunnels
Road tunnel ventilation with efficient CFT tunnel jet fans
The ventilation of road tunnels is of great importance to prevent the accumulation of vehicle exhaust gases and to maintain the air quality in the tunnel.
In view of the increase in electric vehicles, smoke extraction in the event of a fire is also becoming increasingly important.
In order to ensure relevant ventilation during tunnel operation as well as smoke-free escape routes in case of fire, we support you worldwide with CFT tunnel jet fans type SATM.
Metro & rail ventilation with CFT smoke extraction fans
More and more people are moving to the economic metropolises of this world - passenger numbers and public freight services are increasing.
Not only passenger traffic, but also transports, which are partly equipped with potentially flammable cargo, are increasingly taking place underground. In metro and railway tunnels,
CFT smoke extraction fans of SARM type not only provide the necessary safety in case of fire, but also ensure a sufficient supply of fresh air.
