ZYJ wind pressure self-rescuer parameters pressure gas source pressure: 0.3 ~ 0.7MPa output pressure adjustment range: 0.09MPa single device, air consumption: 150 ~ 200L/min gas supply mode: connect pressure air system or a separate gas distribution station (ground) The vacuum noise: ≤ 85dB operation: manually adjusted operating weight: the 0.5kg ZYJ pressure self-help Product Introduction ZYJ pressure self-help is one of the coal and gas outburst mine safety protection measures, it is a fixed permanent self-rescue equipment for coal and Watts and Adams prominent coal mine disaster protection installed in evacuation cavern, was the work place and the mobility of the roadway can also be installed in tunneling and mining face. When the coal and gas outburst or highlight portentously appears, the staff can conveniently enter the self-rescue device, open the pressure valve for disaster prevention. The number of workers who are self-rescue device by certain pressure gas constitute a group, each group head groups generally from 3 to 5, every assembly of the number of heads, the workplace should be considered depending on the number of installed head should be greater than the number of people working in that place. The device system is simple, cheap, is an economical permanent self-help device system. The implementation of standards: MT 390-1995 "the mine pressure self-help device technical conditions"
