Oil for rotary screw compressors for maintenance and reliable operation

Oil for rotary screw compressors performs important functions in the compressor, including lubrication, cooling, and protection of oil-carrying components. In this category, you will currently find Screwlub VG 46 for rotary screw compressors in container sizes ranging from 5 to 1,000 liters.

The compressor oil offered is rated at viscosity class VG 46 and complies with DIN 51506 VDL and ISO 6743/3A. When selecting oil and changing it, always follow the specifications for the respective compressor. Not only viscosity and specifications are crucial, but also the maintenance interval, operating hours, and the type of oil currently in use. Different oils should not be mixed together without a technical evaluation.

Choosing the Right Compressor Oil

✅ Check viscosity class and approval

✅ Follow the manufacturer’s specifications for the compressor

✅ Select the appropriate container size based on maintenance needs

✅ Plan oil changes in conjunction with maintenance intervals

Selecting the Right Oil for Rotary Screw Compressors

Compressor oil is an essential operating fluid for oil-lubricated rotary screw compressors. It lubricates moving components, aids in heat dissipation, and helps protect oil-carrying components. Therefore, when changing the oil, you should not use just any industrial oil, but rather an oil with the properties specified for the machine.

The current product range includes Screwlub in viscosity class VG 46. The product is certified according to DIN 51506 VDL and ISO 6743/3A and is available in container sizes ranging from 5 to 1,000 liters. This allows it to meet the needs of both individual machines and larger maintenance inventories.

Follow VG 46 and the specifications

The viscosity class describes an important characteristic of the oil, but does not replace verification of the manufacturer’s specifications. Before changing the oil, you should therefore check which specification is intended for the existing rotary screw compressor. Especially if the maintenance history is unknown, you should also clarify which oil is currently being used in the system.

Select the container size based on maintenance needs

The available range from 5 to 1,000 liters allows for procurement tailored to specific needs. A small container is often sufficient for individual maintenance tasks, while businesses with multiple compressors or their own maintenance warehouse can stock larger quantities more cost-effectively. Proper storage in clean, sealed original containers is essential.

Things to Keep in Mind When Changing the Oil

✅ Check the maintenance manual and the specified oil quality

✅ Clearly identify the type of oil present

✅ Take the machine’s capacity into account

✅ Coordinate oil changes with filter replacement and maintenance work

✅ Dispose of used oil properly

Compressor oil and maintenance go hand in hand

An oil change is often part of a larger maintenance schedule. Therefore, you should also check whether air filters, oil filters, or other maintenance components need to be replaced based on operating hours. Separate maintenance kits are available in the shop for various rotary screw compressor series.

Buy oil for rotary screw compressors

Anyone looking to purchase oil for a rotary screw compressor should compare the viscosity class, specification, and machine requirements. If in doubt, the exact compressor series and power rating can be used to determine the correct oil.
