Frequently Asked Questions

Is the SRF I/4000 lubricant compatible with my Sullair compressor?

The SRF I/4000 lubricant is designed for Sullair compressors that require this exact fluid specification. It is used in many rotary screw compressor systems, but compatibility should always be confirmed by matching SRF I/4000 in your compressor’s manual or lubrication requirements. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility. 

What type of oil is SRF I/4000?

SRF I/4000 is a partial synthetic blend air compressor lubricant engineered for industrial applications. It is formulated to provide thermal stability, oxidation resistance, and consistent lubrication under load.

How often should the SRF I/4000 oil be changed?

Oil change intervals depend on usage, but manufacturers typically recommend checking oil regularly and changing it on a routine schedule at around 4,000 operational hours. Heavy use or harsh conditions may require more frequent changes.
