roots blower oil
Roots blowers require a specific type of oil for proper lubrication and optimal performance. Roots recommends using its own brand of synthetic lubricant, ROOTS™ Synthetic Oil, for all its rotary lobe products. This lubricant is designed to provide superior performance compared to petroleum-based oils, offering benefits like increased bearing life, extended oil change intervals, and improved equipment reliability.
Here’s a more detailed breakdown:
- Recommended Oil:ROOTS™ Synthetic Oil is the preferred choice.
- ISO Viscosity Grade:For temperatures above 90°F (32.2°C), ISO VG 320 is recommended. For temperatures between 32°F and 90°F, VG 220 is common, and VG 100 is used for temperatures below freezing, .
- Key Properties:This synthetic oil offers high oxidation stability, excellent corrosion protection, high film strength, and a low coefficient of friction.
- Compatibility:ROOTS™ Synthetic Oil is compatible with petroleum-based oils, so no special cleaning is needed when switching from mineral oil.
- Oil Change Intervals:Using ROOTS™ Synthetic Oil can extend oil change intervals by 2-3 times compared to petroleum-based lubricants.
- Alternative Oils:If using an alternative brand, it should be a premium grade, non-detergent oil with rust, oxidation, and foam inhibitors. Automotive-type oils are not suitable.
- Oil Level and Changes:Check the oil level daily when the blower is new and change the oil after the first 100 hours of operation. After that, oil change frequency is determined by oil temperature and operating hours.
- Oil Temperature:You can estimate the oil temperature by multiplying the discharge air temperature by 0.8.
