What Oil Should You Use in Your Sullivan-Palatek Air Compressor?
Sullivan-Palatek builds some of the toughest rotary screw compressors in the industry, but every unit depends on the right oil to stay efficient, cool, and reliable. Whether you run a stationary machine or a portable tow behind, choosing the correct oil will protect your air end and help you avoid unnecessary downtime.
This guide breaks down the best oil options for Sullivan-Palatek compressors and explains when each one should be used.
The Best Oils for Sullivan-Palatek Compressors
As a disclaimer, certain oils are not compatible with each other, and mixing them can cause equipment damage, performance issues, or even system failure. We recommend you always perform a full drain and proper system flush before switching to a different oil type. Consult your equipment manufacturer's recommendations or a qualified technician before making any changes. Okay! Now to the fun part.
1. Palasyn 45
Best for: Standard duty stationary rotary screw compressors.
Palasyn 45 is the go to rotary screw compressor oil for most stationary Sullivan-Palatek machines. It is a high quality PAO synthetic lubricant designed for long service life and stable performance in a wide range of temperatures.
- Designed for heavy industrial use
- Excellent thermal stability and oxidation resistance
- Long drain intervals under normal operating conditions
- Ideal for 24x7 environments
If you have a typical stationary Sullivan Palatek unit operating in normal conditions, Palasyn 45 is usually the right choice.
2. Pallube 32
Best for: Stationary compressors in hotter ambient conditions or systems needing fast oil circulation.
Pallube 32 is a lower viscosity option that flows quickly at startup and performs well in warmer environments. Some Sullivan-Palatek models specify ISO 32 oils depending on duty cycle and temperature.
- Great for high temperature plants or tight mechanical tolerances
- Resists varnish and carbon buildup
- Helps maintain stable air end temperatures
If your compressor runs hot or if your environment sees elevated temperatures, Pallube 32 is a strong pick.
3. PalExtra 44
Best for: High performance stationary compressors requiring extended life oil.
PalExtra 44 is Sullivan-Palatek’s premium lubricant. It is engineered for maximum thermal stability, improved demulsibility, and longer drain intervals than standard synthetic oils.
- Premium synthetic base stock
- Exceptional resistance to oxidation
- Ideal for plants that demand long intervals between PM
- Reduces operating temperature when compared to standard oils
If uptime is critical or you prefer to stretch maintenance intervals without sacrificing protection, PalExtra 44 is the top tier choice.
4. WeatherAll Fluid
Best for: Portable Sullivan-Palatek compressors.
WeatherAll Fluid is formulated specifically for portable tow behind compressors that operate in dirt, dust, and wide outdoor temperature swings. Portable compressors experience harsher conditions than stationary units, and this fluid is designed to handle that workload.
- High protection in dusty environments
- Stable in both cold mornings and hot afternoon conditions
- Ideal for construction, farming, and trenching applications
- Recommended for portable Sullivan Palatek diesel units
If you tow it to the job site, WeatherAll is the correct oil to run.
How To Choose the Right Sullivan-Palatek Oil
- For stationary compressors in normal factory environments: Use Palasyn 45.
- For stationary compressors running hot or in warm climates: Use Pallube 32.
- For extended life requirements: Use PalExtra 44.
- For portable tow behind compressors: Use WeatherAll Fluid.
How Often Should You Change Sullivan-Palatek Compressor Oil?
Rotary screw compressor oil change intervals depend on the oil type and operating conditions. In general:
- Standard synthetic oils: Every 4,000 to 8,000 hours or annually
- Premium extended life oils: Up to 8,000 hours under the right conditions
- Portable compressor oils: Follow the manufacturer intervals due to harsher outdoor environments
You should also change your air filter, oil filter, and separator at the recommended intervals to get full performance from your oil. You can find all compressor oils here:
Final Thoughts
Sullivan-Palatek makes durable compressors, but like every rotary screw machine, they perform best with the right oil at the right interval. Whether you need daily reliability on the plant floor or dependable performance on a construction site, choosing the correct fluid will protect your air end and help your machine run at its best.
