Adding oil to a skid mounted air compressor is a crucial maintenance task that ensures the efficient and long - lasting operation of the equipment. As a skid mounted air compressor supplier, I've seen firsthand the impact of proper oil maintenance on the performance of these machines. In this blog, I'll guide you through the process of adding oil to a skid mounted air compressor, sharing best practices and tips along the way.
Understanding the Importance of Oil in a Skid Mounted Air Compressor
Oil plays several vital roles in a skid mounted air compressor. First and foremost, it lubricates the moving parts within the compressor, reducing friction and wear. This not only extends the lifespan of the components but also improves the overall efficiency of the machine. Without proper lubrication, the compressor would experience increased heat generation, leading to premature failure of parts such as pistons, bearings, and valves.
Secondly, oil helps to seal the compression chamber. A good oil film prevents air leakage, which is essential for maintaining the desired pressure levels in the compressor. This ensures that the compressor can deliver the required amount of compressed air for your applications, whether it's for industrial manufacturing, construction, or other uses.
Finally, oil acts as a coolant. It absorbs and dissipates the heat generated during the compression process, preventing the compressor from overheating. Overheating can cause a range of problems, from reduced performance to complete breakdown of the compressor.
Pre - adding Oil Checks
Before you start adding oil to your skid mounted air compressor, there are a few important checks you should perform.
1. Read the Manufacturer's Manual
The manufacturer's manual is your go - to resource for all information related to your compressor. It will provide specific details about the type of oil to use, the oil capacity, and the recommended oil change intervals. Different compressors may require different types of oil, such as synthetic or mineral oil, depending on factors like the operating temperature, pressure, and the type of compressor (e.g., reciprocating or rotary). Make sure to follow the manufacturer's recommendations to avoid any potential damage to the compressor.
2. Check the Oil Level
Most skid mounted air compressors are equipped with an oil sight glass or dipstick. Locate this indicator and check the current oil level. If the oil level is below the minimum mark, it's time to add oil. However, if the oil appears dirty, cloudy, or has a burnt smell, it may be necessary to change the oil completely rather than just topping it up.
3. Inspect the Compressor for Leaks
Check the compressor and its associated hoses, fittings, and connections for any signs of oil leaks. Leaks can not only lead to a loss of oil but also pose a safety hazard. If you detect a leak, it should be repaired before adding oil to the compressor.
Step - by - Step Guide to Adding Oil
Once you've completed the pre - adding oil checks, you're ready to add oil to your skid mounted air compressor.
1. Gather the Necessary Tools and Materials
You'll need the appropriate type of oil as recommended by the manufacturer, a funnel, and possibly a clean rag to wipe up any spills. Make sure the oil is clean and free from contaminants.
2. Turn Off the Compressor
For safety reasons, always turn off the compressor and disconnect it from the power source before adding oil. This will prevent any accidental start - up while you're working on the machine.
3. Locate the Oil Fill Port
The oil fill port is usually clearly marked on the compressor. It may be covered by a cap or plug. Remove the cap or plug carefully, being cautious not to drop any debris into the port.
4. Use a Funnel to Add Oil
Insert the funnel into the oil fill port. Slowly pour the oil into the compressor, taking care not to overfill. Refer to the manufacturer's manual for the correct oil capacity. You can also use the oil sight glass or dipstick to monitor the oil level as you add oil.
5. Check the Oil Level Again
After adding the oil, wait a few minutes for the oil to settle. Then, check the oil level using the sight glass or dipstick. The oil level should be between the minimum and maximum marks. If it's too low, add a little more oil; if it's too high, carefully drain some oil until the level is correct.
6. Replace the Oil Fill Cap
Once the oil level is correct, replace the oil fill cap securely. Make sure it is tightened properly to prevent any oil leaks.
Tips for Maintaining the Right Oil Level
- Regularly Monitor the Oil Level: Make it a part of your routine maintenance schedule to check the oil level in your skid mounted air compressor. This will help you catch any potential issues early, such as excessive oil consumption or leaks.
- Keep Records: Maintain a log of when you add oil and the amount of oil added. This can be useful for tracking the oil consumption pattern of your compressor and for detecting any changes that may indicate a problem.
- Store Oil Properly: Store the oil in a clean, dry place away from direct sunlight and heat. This will help preserve the quality of the oil and prevent contamination.
Related Products and Their Oil Requirements
As a skid mounted air compressor supplier, we also offer a range of related products, such as Compressor Skid, Hydraulic Gas Compressor, and Hydraulic Motor Driven Air Compressor. Each of these products has its own specific oil requirements, which are detailed in their respective manufacturer's manuals.
Compressor skids are designed to provide a compact and integrated solution for air compression. They often house multiple components, including the compressor, motor, and control systems. The oil requirements for compressor skids depend on the type of compressor installed and the operating conditions.
Hydraulic gas compressors use hydraulic power to compress gas. These compressors typically require high - quality hydraulic oil that can withstand the high pressures and temperatures associated with the compression process.


Hydraulic motor driven air compressors are powered by hydraulic motors. They require oil that can lubricate the motor and the compressor components effectively. The oil should also have good anti - wear and anti - oxidation properties to ensure long - term performance.
Conclusion
Adding oil to a skid mounted air compressor is a relatively simple but essential maintenance task. By following the steps outlined in this blog and adhering to the manufacturer's recommendations, you can ensure that your compressor operates efficiently and reliably for years to come.
