A long-term ventilation mode is typical in conditions of normal methane emanation whereas a short-term ventilation is applied after shotfiring. For adjustment of fan delivery, jet regulation is applied by blocking some parts of nozzle passages. The fan design offers its concatenating when it is stipulated by the pipeline length and resistance.VMP- 4M ventilation fan is recommended to use with the pipeline of dia.400 mm mainly.
Advantages:
- the fan works both in injection and induction
- economic
- best price for the quality provided
- unique design of the VMP-4M fan allows its application in highly explosive mine workings
