• Dual-purpose machine: Uses pneumatic vacuum generator for both oil extraction and oil refilling.
• Oil is extracted into the tank via vacuum suction, avoiding the inconvenience and contamination of manual pouring. Pneumatic refilling allows for controlled speed, making the process quick and efficient.
• Compact single-tank design is convenient and suitable for places like gearboxes where both extraction and refilling are needed.
• Vacuum or pressure can be stored for use anywhere, allowing oil to be extracted or dispensed as needed.
• Dual functionality in one device saves space and reduces equipment costs.

Recommendation:
When using the device for both oil extraction and refilling, please extract relatively clean waste oil (e.g., gear oil) to prevent contamination of the oil tank, which may affect its use as a refilling unit.
