1PC DC 3V–4.5V 370 Electronic Starter Diaphragm Air Pump A compact diaphragm air pump designed for lowvoltage DC systems. The 370 electronic starter model provides reliable, oil air delivery for small projects and devices that require steady lowpressure airflow and dependable startup at 3–4.5 volts. Key benefits Reliable lowvoltage operation: Runs on DC 3V–4.5V to suit batterypowered or lowvoltage electronic systems. Dependable startup: Electronic starter improves consistency at low voltages for faster, more reliable motor engagement. Quiet, oil airflow: Diaphragm design produces pulsed, lowpressure air without oil lubrication, reducing maintenance and contamination risk. Easy integration: Compact 370format pump is suitable for tight spaces and hobbyist or prototype assemblies. Key attributes Voltage: DC 3V–4.5V (operate within this range for reliable performance). Model: 370 electronic starter diaphragm air pump. Type: Diaphragm air pump (electronic starter). Quantity: 1 piece. Functionality and performance Produces steady lowpressure airflow suitable for small pneumatic tasks and continuous or intermittent operation. Electronic starter helps ensure the motor begins turning reliably even at the lower end of the operating voltage range. Diaphragm mechanism delivers air without oil, making it appropriate for applications where contamination must be minimized. Compatibility and installation Designed for DC systems within the specified 3V–4.5V range; confirm power source voltage before connecting. Compact 370format design fits many small assemblies and hobby projects; mount securely to minimize vibration. Typical wiring: standard DC positive and negative connections; observe correct polarity. Suggested applications Aquarium aeration and oxygenation for small tanks or DIY sponge filter setups where lowpressure air is required. Small pneumatic actuators, vacuum pickups, hobby inflatables, or modelmaking tasks that need reliable lowvoltage airflow. DIY science projects, plant seedling oxygenation or aeroponics experiments, and other lowpower air delivery uses. Practical notes Operate only within the specified voltage range (3V–4.5V) to avoid damage and ensure longevity. Use appropriate smalldiameter tubing and secure fittings to prevent air leaks. Allow adequate ventilation and stable mounting to reduce heat buildup and vibration during operation.
