Parameters

Product features:

XL-805 is a high-vacuum diffusion oil that rectifies highly refined synthetic oil with a high-vacuum distillation device. Because it has superior heat resistance and oxidation resistance stability, it can be used for a long time.

Features
1. Low vapor pressure Because of the low vapor pressure, there is very little Oil Back, and a high vacuum can be maintained.
2. Reliability Because of the high exhaust speed, the target reaching pressure can be obtained quickly. Also because the latent heat of evaporation is small and the range of operating power is wide, power consumption can be reduced.
3. Stability Because it has excellent chemical stability such as heat resistance, oxidation resistance, radiation resistance, and active gas resistance, it can maintain the performance of the vacuum pump for a long time.
