HF Dry oil-free vacuum pumpDetailed product description：

Application range of HF dry oil-free vacuum pump

Purpose
The HF series variable capacity oil-free vacuum pump is particularly suitable for use in the chemical and pharmaceutical industries, with extremely strong capabilities
The ability to extract 100% of organic solvents (such as alcohol, gasoline, butane, etc.) gas can also ensure long-term reliable continuous operation, and the extracted important gases can achieve 100% recovery and reuse. This series of products is equipped with a drainage device, which can gradually discharge the condensed liquid in the pump chamber out of the pump, ensuring the efficiency of the pump and extending its service life.

Features
Clean and empty, no pollution to the environment;
Within the process chamber, there is no internal contact between components and no oil or gas pollution;
Strong extraction ability, stable operation, and low noise;
Low maintenance cost.

use in combination
As a front-end pump matching for Roots pumps, molecular pumps, titanium sublimation pumps, sputtering ion pumps, and low-temperature pumps, it can form clean oil-free medium vacuum and oil-free high vacuum units.
