1.1. Efficiency Power Output: Driven by a micro DC motor, the diaphragm is activated to reciprocate through the internal mechanical eccentric movement of the pump body. Utilizing the interaction of compression (closing the suction port and exhaust port to create a slight positive pressure) and tension (closing the exhaust port and suction port to generate a vacuum), it enables efficient inhalation and discharge. 2.2. LowNoise and EnergySaving Features: Suitable for various instruments and equipment, it operates with low noise and minimal power consumption, reducing environmental disturbance. Particularly ideal for scenarios requiring vacuum performance while ensuring user experience. 3.3. Wide Tube Compatibility Range: Designed for tubes ranging from 4.5 to 6 mm to ensure performance after connection. The maximum outer diameter is compatible with 6.5 mm, providing flexibility when connecting tubes to different devices and adapting to a variety of applications. 4.4. Durable and Robust: The product design is sturdy and longlasting, capable of withstanding harsh working conditions, maintaining stable performance over longterm use, and reducing failure frequency.
