We are offering the High Vacuum Electric Suction Apparatus(Dy-980d) : 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 this type of electric suction apparatus adopts completely plastic panel design, which makes it more fancy and fashionable.

-> The device of intercepting oil for circumference 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 65292 50hz 1hz max negative pressure:8805 0.09mpa noise:8804 65db (a) power:8804 180va pumping rate:8805 20l/min reservoir capacity: 2500ml/pc, 2pieces etc.
