12V 5L/min 65-120kpa Negative Pressure Vacuum Pump

12V 5L/min 65-120kpa Negative Pressure Vacuum Pump

1. Working voltage: DC9V~14V
2. Rated voltage: DC 12V
3. Rated current: 500mA
4. Rated power: 6W
5. Suction: 5L/min
6. Vacuum: 65kpa
7. Pressure: 120kpa (MAX)
8. Noise: 60db
9. Applicable to 4.5-6mm tubes, mainly about hardness, the outer diameter is 6.5mm
10. Driven by a micro DC motor, it drives the internal mechanical eccentric eccentric movement, and the eccentric movement drives the reciprocating movement inside the diaphragm, thereby compressing the fixed volume of air in the pump chamber (the compressed air intake port is closed, and the exhaust port forms a slightly open positive pressure), stretching (the compressed exhaust port is closed, and the negative pressure air intake port is opened), and the sucked air is accompanied by the external atmospheric pressure difference. Under a pressure difference, the gas pressure (inhalation) enters the pump chamber and is discharged from the exhaust port
11. Mainly used in electrical products, industrial products, vacuum preservation machines, automobile exhaust modification equipment, medical equipment, gas analysis sampling, instrumentation and other fields
12. Maintenance-free, oil-free pump, no pollution to the transmission medium, can work continuously for a long time
13. Small size, stable and reliable, handheld pump suction instrument, low noise, low power consumption
