Why varnish is a hidden threat to compressor system reliability
Varnish deposits lead to filter plugging, bearing wear, valve failures, and carbon buildup
Over time, varnish accumulation can result in frequent shutdowns, emergency repairs, and costly disruptions to operations
Annual losses can be significant and depending on application can run into the millions

Prevents re-adhesion –
cleaner breaks down varnish
into fine particles that don’t
re-stick or clog filters |
