Feature: 1. STABLE PERFORMANCE: The small vacuum pump has a high air and good performance with a water of 1.5L‑3.2L 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, , beauty, massage, breast pumps, vacuum packaging machines and adult products.
