Q: Is this oil suitable for my screw/reciprocating/vane compressor?
A: Yes. Our COOMCOOL AIRL PD series is specifically formulated for various compressors. Please match the ISO Viscosity Grade (VG) to your equipment's manual: PD 32/46 for screw, PD 68/100 for reciprocating, and PD 150 is ideal for vane and high-temperature reciprocating compressors.

Q: What is the recommended oil change interval?
A: For oil-injected screw compressors under normal conditions, a change interval of around 2,000 hours is typical. For reciprocating compressors, the interval depends heavily on the operating load and temperature. We recommend consulting your machine manual and monitoring oil condition for optimal service life.

Q: Why is your oil more expensive than some others?
A: Our oil is formulated from highly refined mineral base oils with premium additives. This provides superior thermal-oxidative stability, resulting in longer oil and filter life, less carbon deposit, and better protection against wear and corrosion. This translates to lower total maintenance costs and less downtime, offering greater value.

Q: Can I mix this oil with another brand or type in my compressor?
A: No, we do not recommend mixing. Mixing different lubricants can lead to chemical incompatibility, reduced performance, and potential damage to your compressor. Always fully drain and flush the system before switching to our oil or any new lubricant.

Q: How does it perform in very hot environments or high-temperature operations?
A: Our PD series features excellent high-temperature stability. Oils like PD 100 & PD 150 have high flash points (up to 255°C) and are designed to resist oxidation and thinning at elevated temperatures, making them reliable for use in demanding, high-heat conditions.
