HUXI 2XZ Series, Vacuumpump manual
Rotary vane vacuum pump
The rotary vane vacuum pump is a basic device used to remove gases from sealed containers. It can be used alone or as a booster pump, diffusion pump, pre-stage pump for molecular pumps, maintenance pumps, and pre-pumping for titanium pumps. It can be used for vacuum drying, freeze drying, vacuum degassing, vacuum packaging, vacuum adsorption, vacuum forming, coating, food packaging, printing, sputtering, vacuum casting, instrumentation and meter support, refrigerators, air conditioning assembly lines, and laboratory vacuum operations and supporting applications.
Product features
Thanks to thorough low-noise design and precise machining, noise reduction is achieved.
Specially designed gas ballast valves are equipped to prevent oil mixing and extend the service life of the pump.
Designed with international similar products, compact size, light weight, low noise, and easy to start.
Equipped with vacuum drying ovens, freeze dryers, and printing machinery.
Compatible with small-diameter adapters, KF interfaces, and flange connectors.

- B Series rotary vane vacuum pump
This pump is suitable for extracting air and other general gases. The advantage of using a forced oil pump inlet device allows continuous operation even at an inlet pressure ≤ 1.33×10³. It can be used independently, but also as a pre-pumping pump for booster pumps, diffusion pumps, molecular pumps, maintenance pumps, and pre-pumping pumps for titanium pumps. It is widely applicable for vacuum metallurgy, vacuum coating, vacuum drying, freeze drying, vacuum degassing, vacuum packaging, vacuum adsorption, vacuum forming, food packaging, printing, sputtering, photovoltaics, aerospace technology, chemical engineering, electronics, refrigerators, air conditioning assembly line features, laboratory vacuum operations, and supporting applications.
