Huada HDV-3900 oil-lubricated twin-screw vacuum pump

Huada HDV-3900 oil-lubricated twin-screw vacuum pump

The ultimate pressure of Huada HDV series oil-lubricated twin-screw vacuum pump can reach 0.3mbar (absolute pressure), which saves more than 40% energy on average compared with traditional water ring vacuum pumps; the efficiency is better at. 200mbar(A)-600mbar(A).

1.High stability：The advanced speed regulation and frequency conversion technology of the frequency converter can significantly reduce the customer's use cost and provide stable and reliable vacuum pressure.

2.High-definition touch screen：High-performance 7-inch large touch screen is simple and fast, 256MDDR runs faster and responds more smoothly, is durable, and has a constant pressure and temperature design.

3.High efficiency oil：The extra-large oil separator tank design ensures the rough separation effect, the large-capacity built-in multi-core oil separator is easy to maintain, and the oil content is less than 3PPM.

4.High quality accessories：Polyester fiber filter material has high filtration efficiency and large dust holding capacity. It adopts vacuum-specific air intake control valve to improve efficiency and reduce consumption.

5.High speed cooling：The oil cooling adopts ultra-wide bionic fan blades to make the cooling air volume and pressure more stable and the airflow noise lower.

6.Efficient host：The perfect match of IE4-IP55 high-efficiency permanent magnet motor and high-efficiency host, direct drive, avoids belt transmission loss.
