Specification Brand : Intoipush BulletPoint1 : Efficient: Powered by a miniature DC motor, the pump drives internal mechanical eccentric motion, resulting in reciprocating motion of the diaphragm. It compresses (closing the compression suction port, forming a slight positive pressure at the exhaust port) and stretches (closing the compression exhaust port, opening the negative pressure suction port) to suction and expel air. BulletPoint2 : Low Noise: Mini vacuum pump is suitable for use in various instruments and equipment. It operates with low noise and low power consumption. Especially suitable for environments with high negative pressure requirements. BulletPoint3 : Compatible with 4.5‑6mm Tubes: Designed to work with tubes within the 4.5‑6mm range, ensuring optimal performance. The larger outer diameter is 6.5mm, providing versatility for different applications. BulletPoint4 : LASTING: This vacuum pump is built to last, featuring a robust design that withstands demanding operating conditions. BulletPoint5 : Widely Used: Primarily used in electrical products, industrial equipment, vacuum sealers, automotive exhaust emission control systems, medical devices, gas analysis sampling, instrumentation, and more. It requires no maintenance, has an oil fr design, does not contaminate the transferred medium, and can operate continuously for extended periods. BulletPoint6 : 【Low Noise】The external silencer and the thickened wall ensure good noise reduction, giving you a quieter and more comfortable working environment. The silencer also has a filtering performance, making the input air pure BulletPoint7 : 【Easy to Carry】With its small size(11.02*7.48*5.7in) and lightweight(24.25lbs), and without an air tank, you can easily carry it to any workplace BulletPoint8 : 【Customer Service】We aim to provide quality products and services.
