Piston Compressor Oils
At Airpower we stock mineral oil and synthetic oil for any air compressor or vacuum pump. We keep synthetic oil with a H2 food grade classification. We can supply international acceptable certificates for the oil.
Our Piston Compressor Oils
Airpower only sells approved original equipment manufactured oil. It is very important to use the correct oil for the specific compressor.
Reciprocating piston compressors do need high pressure and high-temperature oil. The oil must have anti-wear, anti-foaming, and anti-oxidation characteristics with the correct viscosity.
The wrong oil may cause carbon on the valves and delivery pipe and can destroy the compressor. Wrong oil can also pass the rings and pass all the oil down the delivery pipe into the air system
Our 30 monograde mineral oil has an expected life of 500 hours.
Every 500 hours the oil and air filter must be replaced.
Please do not mix different oils in a compressor.
The normal running temperature for mineral oil is 60°C up to 95 °C.
If the oil runs too cold, condensation will take place in the oil.
The maximum allowable temperature is 105 °C.
H2 Food Grade Synthetic Oil:
The expected life of this CPI Synthetic Lubricant is 2000 hours.
Every 2000 hours the oil and air filter must be replaced.
Please do not mix different oils in a compressor.
The normal running temperature for synthetic oil is 60°C up to 95 °C.
Although synthetic oils can withstand much higher temperatures, Airpower will not recommend temperatures of higher than 105 °C.
Mineral Oil vs Synthetic Oil
Synthetic oils have 4 to 12 times the life expectancy of mineral oil. This reduces your service intervals, although you still have to replace your oil filter and air filter at the recommended intervals.
Synthetic oils run cleaner and cooler than mineral oils but are much more expensive.
With synthetic oils, you can get H1 and H2 approved food-grade oils. This is normally used in food processing factories.
The Purpose of Oil in a Piston Compressor
The oil in a piston compressor lubricates all the moving parts but also cools the machine, it also prevents friction on the pistons and other moving parts while serving as a sealant to prevent leakage.
The oil carries the heat away from the heated parts in the machine, seals the air between the pistons which cools the compressor, allowing the compressor to run continuously without overheating.
Lack of compressor oil can lead to leaks, reducing the efficiency of your compressor and the maximum pressure it can produce.
Ideal Oil Temperatures in Air Compressors
For every 10 °C the oil is increasing in temperature, you half the life expectancy of the oil. If the oil temperature is running for long periods of time at lower than 65 °C, moisture builds up in the oil and can cause rust and loses the lubrication function.
The oil with too much moisture becomes milky in colour. The maximum temperature recommended is 105 °C on the oil. Above this temperature, your oil starts to break down and can also catch alight.
What Oil Should I Use In My Air Compressor?
Never use multi-grade oil in any compressor. It carbons up on the valves and outlet pipes. Use a straight monograde mineral oil only.
Why do some people use synthetic oils? Synthetic oils have 4 to 12 times the life expectancy of mineral oil. This reduces your service intervals, although you must still replace your oil filter and air filter at the recommended intervals.
Your oil and separator filter will last much longer. With synthetic oils, you can get H1 and H2 approved food-grade oils. This is normally used in food processing factories.
Never mix different synthetic oils by topping up with a different brand of oil. These oils can react with one another and become a thick syrup sludge and ruin the complete compressor. Synthetic oils run cleaner and cooler than mineral oils but are much more expensive.
At Airpower we stock mineral oil and synthetic oil for any air compressor or vacuum pump. We keep synthetic oil with an H1 and oil with an H2 food-grade classification.
We can supply internationally acceptable certificates for the oil. Enquire about our Piston Compressor Oils today!
Refrigerated Dryers
Refrigerated air dryers from 750 liters/min up to 17000 liter/min ex-stock. Larger ex overseas. Dew point 4°C under pressure. Automatic drain pre and manual drain after filters.
Screw Compressors
Screw compressors have no valves or other mechanical forces to cause imbalances unlike piston compressors.
Compressor Components
Airpower keeps universal spare parts for compressors. Pressure switches, non return valves and safety valves are universal to all compressors. Bottom entry filters/ regulators, electric motors and starters can be used for many makes of compressors.
