Product Description
VacOil ECO Grade is a high viscosity vacuum pump oil designed for use with direct drive rotary vane pumps and is ideal for Freeze Drying applications. The quality formula improves pumping cycles, lowers maintenance costs, cools the pump and extends pump life. VacOil vacuum fluids are superior quality molecularly distilled vacuum pump oils engineered to perform and provide the ultimate protection from wear that causes pump repairs and pump failures. Lab tests reveal superior performance such as viscosity change and sediment weight when tested against competitive brand oils, outlasting and outperforming other vacuum oils.

General Vacuum Pump Maintenance for Freeze Dryers
The most common complaint about freeze drying is loss in vacuum pressure. This loss is most often due to one of three things:
- A leak in the freeze dry system
- Dirty/Contaminated vacuum pump oil
- An issue with the vacuum pump
Is it time to change the vacuum pump oil?
Often, the best place to start troubleshooting is by performing a vacuum pump oil change. When the oil in a rotary vane pump starts to look cloudy or dirty, it’s time to change the oil! The frequency for oil changes in freeze drying is much higher than other applications due to the demand placed on the vacuum pump and the volume of moisture that is being displaced.
Do I have the right vacuum pump?
Because freeze drying requires an oil based rotary vane pump to maintain the depth of vacuum, it is important to choose the right pump. A standard rotary vane pump works well with aqueous-based solutions.

Best Oil I have used for Freeze Dryer
Used multiple Brands of oil for my freeze Dryer. I can run the ECO VacOil longer than the other brands I have tried. Other oil brands have turned a dark color after 1 freeze dryer cycle, this oil has not discolored after 1 use. Better Price than competitors and Better results!!
