Atlas Copco Genuine Original Oil Filter 1621737890

Atlas Copco Oil Filter 1621737890

The Atlas Copco Oil Filter 1621737890 is an oil filtration component for oil-injected screw compressors. Atlas Copco’s official product page identifies the part as “FILTER OIL FOR OIL INJECTED SCREW COMPRESSOR” and states that the filter captures dust, deposits and other foreign particles to help maintain clean oil flow to the compressor element.

The 1621737890 Oil Filter is installed in the compressor’s lubrication circuit to filter contaminants from the circulating compressor oil.

During operation, compressor oil can collect dust, deposits and other particles. Effective filtration helps prevent these contaminants from circulating through the compressor element and other lubrication-system components.

By maintaining cleaner oil circulation, the filter supports reliable compressor operation and helps protect critical internal components from contamination.

Replacement & Maintenance

Oil-filter condition is an important part of routine compressor maintenance.

A restricted or contaminated oil filter can affect oil circulation and compressor operation. Replacing the filter with the correct part helps maintain the intended lubrication-system configuration.

Always verify the compressor model and serial number before ordering, because the correct filter can vary between compressor models and configurations.
