When ventilating blind development workings the operation modes of the fan are changed depending on the amount of air consumed. A long-term ventilation mode is typical in conditions of 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 amount of air supplied depends upon the air pressure before the nozzle.Contamination of two VMP-6/1 ventilation fans is applied to increase pressure difference, provided by ventilation unit.
VMP-6/1 fan is recommended to be used with pipelines dia. 600 and 800 mm.
Advantages:
- the VMP-6/1 fan is equipped with GSHP noise muffler to reduce noise level to the specified sanitary requirements
- despite a small size, VMP-6/1 fan efficiency is higher than of similar electric drive fans
- the fan works both in injection and induction
