4lsingle-Stage Rotary Vacuum Pump 50Hz 8cfm/60Hz 9.5cfm

S- 145-4L uses aluminum alloy as the outer cover. It is light and beautiful. When using this pump, the temperature of evacuating gas should be no higher than 40C and the environment temperature should be kept between 5C and 40C. When the gas is pumped, the diameter of the container''''s vacuum tube should be no smaller than that of the air inlet of the vacuum pump. There should be good air proof on the connector and valve of the tube, and strict cleaning in the tube.
It is used for vacuum refrigeration, mechanical printing, automobile reparation, refrigeration recovery devices, photo-engraving, vacuum packaging and so on.
