Why Upgrade to Polyester Over Standard Paper Filters: Superior Durability: Polyester media resists moisture, temperature swings, and vibration, making it ideal for compressors operating in harsh or variable environments. Longer Service Life: The synthetic fibers hold more dust and contaminants before restriction, allowing for longer maintenance intervals. Washable & Reusable: Unlike disposable paper filters, polyester elements can often be cleaned or blown out with compressed air to restore performance. Consistent Airflow: Polyester maintains stable airflow even as it loads with dust, reducing strain on your compressor and improving efficiency. Added Pre-Filter Protection: The removable foam pre-filter traps larger particles and can be easily washed and reused, extending the life of the main element. Ideal For: Any Quincy air compressor or compatible unit using filter numbers 110377E100 or 110377E904, as well as other compressor systems operating in dusty, high-demand, or industrial environments where cleaner intake air and longer filter life are essential.
