The KPM27W-12B 370 DC Air Pressure Pump is a compact and high-efficiency mini diaphragm-type air pump designed for DIY electronics, robotics, embedded systems, and small air inflation applications. Operating over a wide DC voltage range of 6V to 12V, this pump offers flexibility for battery-powered and regulated power supply systems.
Powered by a 370 series brushed DC motor, the pump delivers stable air pressure output while maintaining compact dimensions. The 27mm pump body diameter allows easy installation in space-constrained projects. The semi-transparent housing enables partial visibility of internal components, which is useful for educational demonstrations and testing environments.
This air pump is suitable for air circulation, pressure generation, inflators, pneumatic experiments, medical demonstration models (non-clinical), and automation prototypes. It can be controlled using relay modules, MOSFET drivers, or transistor-based switching circuits when interfaced with microcontrollers such as Arduino, ESP32, Raspberry Pi, or STM32.
