Electric suction apparatus Features: Adopting oil-free piston pump Clean-without pollution of oil and smoke Convent-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 Complete plastic panels, hand-switch and foot-switch for operating easily. Select negative pressure at will with no level for pressure adjustment, and overflow protection mechanism, safe and reliable. Principle technical data: Max negative pressure: ≥0.09MPa Noise:≤ 65 dB (A) Power: ≤180VA Pumping rate: ≥20L/min Reservoir capacity: 2500mL/pc, 2pieces Note: Not suitable for continuous use in the induced abortions and for the inflammable or explodable surroundings. Max continuous working time is 30 minutes, continuity rate: 50% Electrical appliance safety requirement: Class I, Type B
