SPEEDAIRE 3FMX7 Compressor Oil 1 gal Can ISO 46
Semi-synthetic ISO 46 compressor oil in a one-gallon can, formulated for Speedaire rotary screw compressors with a viscosity index of 107 and flash point of 246 degrees C
- ISO 46 viscosity matches rotary-screw compressor specs
- Semi-synthetic base oil protects components under load
- Viscosity index 107 keeps flow stable across temperatures
- High 246 °C flash point reduces fire risk
- One-gallon can sized for convenient top-ups
Product Identity
SPEEDAIRE 3FMX7 is a semi-synthetic compressor oil formulated to ISO viscosity grade 46. It comes in a one-gallon can and carries a viscosity index of 107 with a flash point of 246 degrees Celsius. The fluid is not food-grade and is intended for industrial rotary screw compressors.
Replaces Mineral Fluids
This oil upgrades from conventional mineral lubricants in Speedaire rotary screw compressors. The semi-synthetic base and 107 viscosity index deliver more stable viscosity across temperature swings, reducing deposit formation and extending drain intervals. The improvement is worth it when operating hours are high or ambient temperatures vary widely.
Compatibility Check
Verify that your rotary screw compressor specifies ISO 46 viscosity and accepts semi-synthetic lubricants. Confirm the fluid is not required to be food-grade for your application. Ensure the fill port and reservoir capacity match a one-gallon container for convenient top-off or complete change.

Questions about this item
What ISO viscosity grade does the SPEEDAIRE 3FMX7 oil meet?
The oil meets ISO viscosity grade 46, giving it the thickness profile recommended for Speedaire rotary screw compressors.
How do you add this compressor oil and what step is often missed?
Shut down the compressor, relieve all pressure, remove the fill cap, pour the semi-synthetic oil until the sight glass shows the correct level, then reinstall the cap securely — forgetting to relieve pressure first is the common mistake.
How often should the oil be changed in a rotary screw compressor?
Change intervals depend on the compressor manufacturer's schedule; the oil's viscosity index of 107 and flash point of 246 °C support extended drain periods, but follow the machine manual for exact timing.
