45W fish tank air pump increasing oxygen pump HAILEA ACO-318

- The case is made of high quality ZL102 Aluminum alloy with radiator,heat-dissipation is more effective. - Driven by electric magnetic motor,adopt straight-line reciprocal motion to produce air and more reasonable in structure. - Adopt SF new-type wearing-resistant material for the cylinder and piston which is of low power consumption. - Oilless design,the compressed air is purified. - Constant remperature and pressure operation to ensure reliable performance. Model: ACO-318 Material: Aluminum alloy Color: Silver+Black Power: 45W Voltage: 220V Frequency: 50Hz Displacement: 70L / min Pressure: 0.02MPA Noise: 50dB Size: Approx 16x9x10cm/6.3x3.5x3.9inch Weight: About 1400g
