Compressor Oil Filter 1638578290

Atlas Copco Compressor Oil Filter 1638578290

The Atlas Copco 1638578290 Compressor Oil Filter is a filtration component used in the compressor lubrication system.

During compressor operation, lubricating oil circulates through the system and can collect contaminants and particles. The oil filter helps remove these contaminants before the oil continues through the lubrication circuit, supporting cleaner oil circulation and protection of internal compressor components.

Atlas Copco’s official parts data identifies the component as COMPRESSOR OIL FILTER, rather than simply a generic oil filter.

Why Replace the Oil Filter?

A compressor oil filter gradually collects contaminants during operation. Replacing the filter at the recommended service interval helps maintain the intended filtration performance.

Replacement may be required when:

• The scheduled maintenance interval has been reached
• The filter is contaminated or restricted
• Oil circulation performance is affected
• The compressor is undergoing a major service
• The filter is being replaced as part of a factory service kit

For the correct maintenance interval, follow the service requirements applicable to the specific compressor model.
