Feature:

• Adopting oil-free piston pump,Clean-without pollution of oil and smoke;
• Convenient-no need add oil to maintain daily;
• Safe-no plus pressure during using;
• No flow backwards pressure when the machine stops, so the liquid won’t flow backwards;
• Completely plastic panel design;
• Intercepting oil for circumfluence which can reduce the oil pollution;
• Easy to carry, low noise,  high negative pressure and large flux;
•  Widely applied in the surgical operations, which needs to absorb phlegm etc;
• Thick liquids and other occasions, which need negative pressure suction;
• Power Voltage: AC220V±22V，50Hz±1Hz
                 Max negative pressure: ≥0.09MPa
• Noise:≤65dB (A);
• Power:≤180VA;
• Pumping rate: ≥20L/min;
• Reservoir capacity: 2500mL/pc, 2pieces.
