Name: 7A-23B electric suction apparatus 
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
7A-23B type of electric suction apparatus adopts completely plastic panel design, which makes it more fancy and fashionable. The device of intercepting oil for circumfluence can reduce the oil pollution. Easy to carry, low noise, high negative pressure and large flux. It can be widely applied in the surgical operations, which needs to absorb phlegm etc thick liquids and other occasions, which need negative pressure suction.
Principle technical data:
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
