Frequently Asked Questions

What does this oil filter do?

This replacement oil filter removes wear particles and contaminants from the compressor’s lubrication system. Keeping the oil clean protects bearings, rotors, and internal components so the machine can operate efficiently and reliably.

How often should this oil filter be replaced?

Oil filters on rotary screw compressors are typically replaced every 2,000 operating hours as part of a standard preventative maintenance interval. Units running in harsh or dirty environments may require more frequent changes.

What happens if this oil filter is not replaced on time?

When an oil filter becomes saturated, it can restrict oil flow or allow contaminants to circulate through the system. This leads to higher operating temperatures, reduced lubrication efficiency, and accelerated wear on internal parts.

Is this compatible with my compressor?

This replacement filter fits compressors that specify Kaeser part number 6.4778.0 / 6-4778-1. It is commonly used on Kaeser rotary screw models such as ASD35, ASD40, ASD50, and ASD60 (depending on configuration), along with other Kaeser units that require this filter number. Always match your original part number to confirm compatibility.

How do I know when it’s time to replace the oil filter?

Signs include restricted oil flow, increased operating temperature, visible contamination during inspection, or simply reaching the recommended maintenance interval. Following your machine’s maintenance plan prevents premature wear and downtime.

Is installation difficult?

Most installations are straightforward: shut down the compressor, relieve oil pressure as required, remove the used filter, and install the new one according to your machine’s service instructions. Always follow proper safety and lockout/tagout procedures.

Can this oil filter be used in any compressed air system?

No. This filter should only be used in systems that call for Kaeser oil filter number 6.4778.0 / 6-4778-1. Compressors that specify a different part number require the corresponding filter for proper fit and performance.
