Huada HDU-550 oil-free screw vacuum pump

Huada HDU-550 oil-free screw vacuum pump

Huada HDU series oil-free twin-screw vacuum pumps have an ultimate pressure of 200mbar (absolute pressure), which can partially replace oil-lubricated screw vacuum pumps, avoid the risk of oil emulsification and deterioration, and can extract a wider range of gas media. It not only saves the cost of replacing lubricating oil, but also saves 30% energy compared to traditional water ring pumps.

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.
