Features:

• Made of high quality stainless steel, anti-rust and durable for long lasting

• High pressure air pump by hand, with oil-water separator, compress dry and clean air into oxygen cylinder.

• With ergonomic design, easy to pump, convenient to operate, time-saving and labor-saving.

• With a pressure gauge on it, you can know when to stop inflating.

• Come with practical accessory for quick and easy use

  
  

  Details:
  

• Tighten the pressure relief screw before pumping up (tighten clockwise); loosen the pressure relief screw after pumping up (tighten counterclockwise)
  

• Non-explosive tube: it's made of imported material, and with its 63MPA pressure resistant design, it is not easy to brittle in the condition of the temperature of -30°
  

• Oil-water separator: make the gas more pure
  

• It takes about 15 to 20 minutes to fill a 0.5L oxygen cylinder about pumping up 600 times
  

• How to use: Please perform the pump test according to the instructions and follow the steps to pump

  Note:

• 1. The high-pressure air pump is a backup air source. Only as a last resort should you use it
  

• 2. Before use, please perform the inflation test according to the instructions and refer to the relevant steps to inflate.
  

• 3. 0.5L oxygen cylinder requires about 600 pumps. After testing, Only two adult men take turns pumping for 15-20 minutes, can the oxygen cylinder be filled up. The pumping efficiency is increased by 20%. 24 pumps = 1MPA, so you can lose weight during pumping.
  

• 4. During the pumping process, the high-pressure pump generates heat due to friction, so it is normal for the tube to heat up, but be careful with this condition
