Feature:1. STABLE PERFORMANCE: The small vacuum pump has a high airflow and good performance with a water flow of 1.5L3.2L per minute.2. CORROSION RESISTANCE: The mini air pump uses engineering plastics with good performance as the shell material, which has good corrosion resistance and durability.3. COPPER CORE COIL: The built in copper core coil is safe and stable, flexible and not easy to break, so the air pump is not easy to heat up during use and has a longer life.4. HIGH EFFICIENCY: Filling time is less than 5 seconds, fast and convenient, high pump efficiency, low noise, long service life.5. WIDE APPLICATION: Small vacuum pumps are mainly used for household appliances, medical, beauty, massage, breast pumps, vacuum packaging machines and adult products.Specification:Item Type: Miniature Vacuum PumpMaterial: Engineering plasticsRated Voltage: DC12VRated Current: 150mAPower: 1.8WDrive Mode: ElectricConveying Medium: AirAir Nozzle Diameter: Approx. 4.2mm / 0.17inVacuum Flow: 1.0-3.5LPMMaximum Pressure: -60Kpa-450mmHgNoise: 65db (30cm away)Life Test: 500 hours (continuous.Package List:1 x Miniature Vacuum Pump
