370 Mini Air Pump Motor DC 6V-12V Micro Vacuum Pump

370 DC Micro Vacuum Air Pump Motor 6V-12V Diaphragm Pump

The 370 Mini Air Vacuum Pump Motor is a compact diaphragm-based DC pump designed to generate airflow and negative pressure in small electronic and mechanical systems. This micro vacuum pump is widely used in DIY robotics, laboratory prototypes, medical instruments, and automated spraying mechanisms. Its lightweight construction and efficient motor make it suitable for portable or battery-powered devices.

The diaphragm mechanism creates continuous suction and airflow while maintaining relatively low noise and power consumption. Because of its small size and simple wiring requirements, the pump is frequently used by students, hobbyists, and developers working on Arduino, ESP32, and Raspberry Pi projects. It is also commonly integrated into beauty care devices, aquarium oxygen supply systems, and experimental vacuum applications. Many educational robotics projects supplied through Bigyan Project rely on this pump for air suction, fluid movement, and pressure experiments.
