What is part number 1630091700?
Atlas Copco 1630091700 is genuine Roto Inject Fluid NDURANCE 4L, supplied as 4 L for Atlas Copco G, GA, GX and GR oil-injected screw compressor series. It is available for international B2B supply with stock, freight and export document support.
This item is catalogued as a compressor lubricant. The exact product designation and part number should remain the purchasing reference because similar container sizes can contain different fluid formulations.
The Roto-Inject Fluid range contains several performance variants and package sizes for oil-injected screw-compressor service. A family name alone is therefore not a complete order reference.
For the 4 L pack, state the number of containers and destination. Smaller packs may be consolidated, but final packing and air or sea acceptance are confirmed per shipment.
