roots blower oil

Roots blower oil is a specialized lubricant designed for rotary lobe positive displacement blowers. It is crucial for proper operation, reducing friction, wear, and extending the life of the blower. Synthetic oils are generally preferred due to their superior performance and longer service life compared to traditional petroleum-based oils.

Key aspects of Roots blower oil:

Purpose:

Lubricates gears and bearings within the blower, reducing friction and wear.
Type:

Synthetic oils like ROOTS Synthetic Oil are often recommended for their oxidation stability, corrosion protection, and film strength.
Viscosity:

Typically, a viscosity grade of ISO VG 100 or 220 is used, but the specific grade can vary based on blower model and operating conditions.
Change Intervals:

Synthetic oils often allow for longer change intervals compared to petroleum-based oils.
Compatibility:

Some synthetic oils are designed to be compatible with existing petroleum-based oils, allowing for a gradual transition.
Specific Recommendations:

Always refer to the blower manufacturer’s recommendations for the correct oil type and specifications for your specific model.

Generally, the old oil is drained and the reservoir is refilled with fresh oil.
Initial oil changes may be recommended after a short period of operation (e.g., one month).
