Application Overview:

Suitable for various vacuum pumping applications such as vacuum refrigeration, automotive maintenance, medical devices, vacuum packaging, gas analysis, printing machinery, etc.

Product Features:

1. Anti-backflow design: The air intake channel is specially designed to prevent oil backflow when the pump stops, avoiding contamination of the evacuated container and pipelines.
2. Eco-friendly design: The oil tank features a layered structure, and an oil-gas separator is installed at the exhaust port to eliminate oil spray and reduce oil mist pollution.
3. Aluminum alloy motor housing: Provides excellent heat dissipation, ensuring long-term continuous operation while maintaining a high-quality appearance.
4. Integrated design: The motor and pump are designed as a single unit, making the product more compact, lightweight, and rational.
5. Special low-temperature & low-voltage adaptation: Ensures reliable startup in cold winter environments.
6. Anti-vibration rubber feet: Reduces vibration and noise.
