Synthetic Ester Lubricant Base Oil
This series of products is a high quality, high flash point, low pour point, anti-coking, anti-carbon, environmentally friendly special ester, can be alone or combined with other synthetic materials, can produce a variety of environmentally friendly fully synthetic or partially synthetic compressor oil.
BASOILS Synthetic Ester Base Oil for Air Compressor Oil is a multi-grade synthetic ester base oil portfolio developed for lubricant manufacturers formulating synthetic and semi-synthetic compressor oils.
The series includes low-, medium-, high-, and high-viscosity ester base oils for different compressor lubricant viscosity targets. Selected grades can be used individually or blended with compatible synthetic and mineral base oils to support lubricant formulations requiring low-temperature fluidity, high flash point, ester polarity, additive solubility, and stable oil-film performance.
With viscosity grades ranging from 7.8 mm²/s to 306 mm²/s at 40°C, the portfolio gives formulators flexibility when designing compressor oils for different operating temperatures, compressor designs, discharge conditions, and finished-oil viscosity requirements.
This product range is intended for lubricant formulation rather than direct end use. Final compressor oil performance depends on the complete base-oil blend, additive package, operating conditions, and validation testing.

| Hydraulic Oil | 50–90% | Ester-containing hydraulic fluid formulations requiring lubricity and low-temperature support |
Recommended treat rates are for formulation reference only. Final dosage should be determined through laboratory testing, additive compatibility evaluation, and finished-lubricant validation.
| Viscosity Range | Available Grades | Typical Formulation Direction |
|---|---|---|
| Low Viscosity | DA22, DA31, DA32, DA34, DA41, TMP108A, TMP108B | Low-temperature compressor oil blends, viscosity adjustment, lower-viscosity industrial lubricant formulations |
| Medium Viscosity | DA51, M25, M32, M46, M50, M68 | General compressor oil formulations requiring balanced flow, lubricity, and oil-film performance |
| Medium-High Viscosity | M80, M100, TM143, POE150 | Higher-viscosity compressor oils requiring stronger oil-film retention |
| High Viscosity | TM306 | Specialized high-viscosity compressor lubricant or industrial oil formulations |
This guide is for initial grade selection only. The final grade should be selected according to compressor type, target finished-oil viscosity, operating temperature, discharge temperature, additive package, oil-consumption target, and field-validation requirements.
Synthetic ester base oil is a lubricant base-oil component used to formulate compressor oils. It can support low-temperature flow, lubricity, additive solubility, oil-film retention, and high-temperature lubricant design, depending on the selected grade and final formulation.
No. This product range consists of base oils for compressor lubricant formulation. A finished compressor oil requires a complete base-oil blend, additive package, and application-specific performance testing.
Lower-viscosity grades such as DA22, DA31, DA32, DA34, DA41, TMP108A, and TMP108B can be considered where low-temperature fluidity is an important formulation target. Final selection depends on the required finished-oil viscosity and compressor operating conditions.
M80, M100, TM143, POE150, and TM306 may be evaluated for higher-viscosity compressor lubricant formulations requiring stronger oil-film retention. Final selection should be based on compressor design, operating temperature, and finished-oil validation.
Yes. Selected grades can be evaluated in blends with compatible PAO and selected mineral base oils. Before commercial production, verify miscibility, viscosity response, additive solubility, seal compatibility, and long-term storage stability.
Ester base oils can be used in compressor oil formulations designed to improve high-temperature stability and deposit control. However, actual coking and carbon-deposit performance depends on the complete base-oil blend, additive package, compressor conditions, and validation testing.
