What Is Javac N15 Light General Purpose Vacuum Pump Oil?
Javac N15 Light General Purpose Vacuum Pump Oil is a high-quality mineral oil designed to keep your HVAC and refrigeration vacuum pumps running smoothly. It’s a light, general-purpose grade that suits a wide range of service and workshop pumps across Australia.

Who Is Javac N15 For?
Javac N15 is ideal for:
- HVAC technicians working on split systems, ducted systems, and commercial refrigeration
- Workshop and service teams needing a reliable, general-purpose pump oil
- Serious DIY users who want to protect their vacuum pump investment
If you need a dependable 5 litre drum of vacuum pump oil for everyday evacuation work, N15 is a great fit.
Key Features at a Glance
- Light general-purpose grade: Suitable for a wide range of rotary vane vacuum pumps.
- Consistent viscosity: Helps your pump achieve and hold deep vacuum levels across typical Aussie temperatures.
- Reduces wear and tear: Proper lubrication protects internal components and extends pump life.
- Good moisture handling: Designed to cope with everyday HVAC evacuation work where moisture can be present.
- Bulk 5 Litre size: Perfect for busy service vans and workshop shelves.
How Javac N15 Protects Your Vacuum Pump
Vacuum pump oil is a core part of the system, not just a consumable. Using the wrong oil can slow your pull-down times, make your pump run hotter, and shorten its life. Javac N15 is blended to:
- Provide a stable film between moving parts, cutting friction
- Help your pump reach a deeper vacuum more quickly
- Reduce the risk of internal corrosion when moisture is present
- Support reliable performance on repeated evacuation jobs
Paired with good evacuation practices, N15 helps keep your pump running clean and efficient, day after day.
When to Choose N15 vs Other Vacuum Pump Oils
Javac N15 is a smart choice when you need a reliable, light grade oil for general HVAC and refrigeration service work. For more demanding applications, you may want to compare it with other oils in the range:
- For heavier-duty or higher-vacuum applications: Consider Javac N16 Premium Vector Pump Oil - 5 Litre Vacuum Pump Oil - S21506 , which is blended for more demanding systems.
- For techs running Fieldpiece pumps or mixed fleets: Fieldpiece High Grade Vacuum Pump Oil is a great partner for RunQuick™-style pumps and bulk workshop setups.
For smaller top-ups or occasional use, you can also look at compact bottle options like the 1 litre Vacuum Pump Oil 1LT .
Why a 5 Litre Drum Makes Sense
For busy tradies and service companies, a 5 litre container is practical and cost-effective:
- Multiple oil changes from a single drum
- Less frequent re-ordering for workshop stock
- Better value per litre than smaller bottles
Keep one drum in the workshop and another in the van so you always have fresh oil on hand when you need it.
Quick Maintenance Tips for Better Vacuums
- Change oil whenever it looks milky, dark, or contaminated.
- Swap oil after evacuating “dirty” systems or burnouts.
- Use the sight glass and pump manual as your guide.
- Store the drum sealed and upright to minimise contamination.
