Indufil® High-pressure Seal Gas Filtration

Most centrifugal compressors today use dry gas seals to contain high-pressure gas, whether on a high-pressure reinjection duty or a low-pressure pipeline machine.

Seal reliability depends upon a continuous supply of clean, dry gas. Indufil's specially designed filters remove liquid and particle contamination and maximize reliable seal operation.
