waterproof fire extinguisher refill station co2 free design for fire extinguisher

Machine Composition

DGS-FM-5A model filling machine including air-driven gas filling pump, precision pressure gauge, pressure reducing valve, high pressure electromagnetic valve, electric control part, and electronic scale, vacuum pump, etc.

Machine characteristics

DGS-FM-5A model filling machine using the compressed air as power source, Through the Suncenter air driven gas booster and filling pump, driving the FM200/NOVEC filling and conveying, when the transmission weight reaches a certain value, the sensor signal is transferred to the gas electromagnetic valve, the driven air will stop automaticlly,and pump stops working.

Then Connecting the  nitrogen gas source, open the high-pressure nitrogen gas valve and start the injection of nitrogen; when precision pressure gauge shows the needed nitrogen pressure then close the nitrogen valve; filling finished; It has the characteristics of small volume, light weight, simple operation, reliable performance. Especially suitable for the filling of FM-200/NOVEC in fire fighting industry.
