Atlas Copco 1630091800 Compressor Oil Replacement Function

1630091800 lubricates the rotating components inside an oil-injected screw compressor and helps the oil-injected airend manage heat during compression. The lubricant also helps create the oil film needed for smooth operation and supports the separation and cooling processes within the compressor system.

Roto-Inject Fluid N-Durance maintains a viscosity of 55 mm²/s at 40°C and a viscosity index of 106. Its -33°C pour point helps the lubricant remain fluid during cold starts, while its low total acid number supports stable lubricant condition at the beginning of its service life.

Replacement Solutions

01 — Lubricant Degradation During Extended Operation

Compressor oil works continuously under heat, pressure, and mechanical movement. As the lubricant ages, oxidation and contamination can reduce its ability to support reliable lubrication and cooling. 1630091800 provides a mineral-based lubricant with a service interval of up to 4,000 running hours or one year under the specified operating conditions.

02 — Heat and Wear Inside the Compressor Airend

The screw element generates heat as it compresses air, while bearings and other moving components require continuous lubrication. 1630091800 supplies the oil film needed to lubricate these components and helps the oil-injected airend control heat during operation.

03 — Cold-Start Lubrication Concerns

Low ambient temperatures can increase oil viscosity and make cold starts more demanding. 1630091800 has a pour point of -33°C, which helps the lubricant maintain fluidity at low temperatures and supports lubrication during startup.

04 — Incorrect Oil Grade or Part Number

Atlas Copco offers several compressor lubricants with different formulations, package sizes, and application requirements. Choosing the wrong lubricant can create maintenance and compatibility concerns. Confirming part number 1630091800, the compressor power range, and the specified lubricant before ordering helps prevent an incorrect oil replacement. Atlas Copco identifies 1630091800 specifically as a 20L Roto-Inject Fluid N-Durance package.
