The Atlas Copco Syn-Coolant 46 (part no. 3003-2015-68) is a fully synthetic compressor lubricant, supplied in 20L drums. The “46” designation follows Atlas Copco’s standard naming convention, corresponding to an ISO VG46 viscosity grade — a mid-range viscosity commonly specified for oil-injected rotary screw compressors operating under standard ambient conditions.
Fully synthetic formulations like this one typically offer better oxidation stability and longer service intervals than mineral-based oils, which translates to less frequent oil changes and more consistent lubrication performance across temperature swings — though actual service intervals still depend on your compressor’s operating environment and duty cycle. If you’re currently using a mineral-based oil and considering switching to this synthetic formulation, a system flush is generally recommended beforehand.

Signs It 's Time for an Oil Change
Rather than relying on a fixed time interval alone,watch for:
– A noticeable darkening or change in oil color/clarity
– Rising discharge or running temperature without a clear external cause
– Increased pressure differential across the oil separator
– Any burnt smell or unusual odor when checking the oil
If you notice any of these,it’s worth sampling the oil or scheduling a change ahead of your usual routine —running on degraded oil accelerates wear on the air end itself.
Flushing When Changing Oil Type
Do You Need to Flush the System?
If you’re switching between oil types (e.g.,mineral to synthetic,or between different synthetic chemistries),a system flush is generally recommended to remove residual oil and prevent cross-contamination.Continuing to top up with a different oil type without flushing can gradually degrade lubrication performance.
Common Questions
Can this oil be mixed with other brands or types?
We recommend against mixing different oil chemistries (mineral,PAO,PAG synthetic)unless confirmed compatible —mixing can cause sludging or reduced lubrication performance.If switching brands,a system flush is the safer option.
How long does one container last?
This depends on your compressor’s oil capacity and running hours — send us your compressor model and typical duty cycle,and we
can help estimate consumption.
How long can this oil be stored before use?
Unopened containers stored properly (sealed, indoors ,stable temperature)retain quality well.Once opened,we recommend using the oil within a reasonable timeframe rather than keeping it as long-term backup stock.
Are these genuine Atlas Copco lubricants?
Yes.Parts are sourced through Atlas Copco distributor channels.
What is the typical lead time?
Common consumables (filters, oil) typically ship within about 1 week. Lead time for other spare parts depends on stock availability — please contact us for a confirmed schedule.
Do you inspect parts before shipment?
Yes. We provide full photos and video of the actual item before shipment, and confirm everything is correct with you prior to dispatch.
What shipping options are available?
If you have your own freight forwarder, we can ship to them directly. If not, we can provide shipping options based on your preference.
