brand new and high quality Features: The for case is made of high-quality aluminum alloy with streamline design. heat-dissipation is more effective . Driven by electric magnetic motor, adopt straight-line reciprocal motion to produce air and more reasonable in structure. Adopt SF3 new-type wearing-resistant material for the cylinder and piston. which is of low power consumption, large air output and high air pressure. Non-oil lubricating design, the compressed air is purified Applications: This product is widely used in farming, aquaculture, outdoor pond and the hotel food, seafood aquaculture market increases oxygen etc. Also can be used as pneumatic, industrial machinery and so on as the supporting products. Air Pump only,other accessories demo in the picture is not included.
