AIR-OPERATED SUCTION-DRAINER

The negative pressure is directly generated through the measuring cup and the tank, and vacuum of the measuring cup and tank can be manually balanced, so that the waste oil extractor that alows the measuring cup andtank to absorb oil together with a larger vacuum capacity, faster and longeloil extraction,and can work without air source. note: The H series cannotpump corrosive fluid.)

通過量杯及罐體直接產生負壓，可手動平衡量杯罐體真空讓量杯罐體真空一體吸油的抽廢油機，其真空容量更大抽油更快更久，可脫離氣源工作。(注:H款不能抽取帶有腐蝕性的液體)。
