P5051A / P05051A Champion Air Compressor Replacement Intake Filter Element

Champion P5051A / P05051A Direct Replacement Polyester Air Compressor Intake Filter with Foam Pre-Filter This high-quality air intake filter element is a direct replacement for Champion part numbers P5051A and P05051A, designed to deliver superior protection, efficiency, and service life compared to standard paper filters. Built for demanding industrial and commercial environments, this element features a durable pleated polyester fiber media secured between protective mesh screens and includes a removable foam pre-filter for enhanced dirt-holding capacity. Specifications: • Height: 4.75" • Inside Diameter: 3" • Outside Diameter: 4.38" • Polyester filter media with removable foam pre-filter Equivalent / Cross-Reference Numbers: Direct replacement for Champion P5051A and P05051A. Also equivalent to AP429 (19P) and upgraded from paper-style filters such as A428, AP428, and 18P. Why Upgrade to Polyester Over Paper Filters: Superior Durability: Polyester resists moisture, temperature fluctuations, and vibration—making it ideal for continuous-duty compressors in harsh or variable environments. Extended Service Life: The synthetic fibers trap more contaminants without restricting airflow, allowing longer maintenance intervals and reduced downtime. Washable & Reusable: Polyester elements can often be gently cleaned or blown out with air, while paper filters must be replaced once dirty. Consistent Airflow & Efficiency: Maintains steady air delivery even as dust accumulates, helping compressors operate cooler and more efficiently. Added Foam Pre-Filter Protection: The removable pre-filter captures larger debris and can be washed and reused, extending the life of the main filter element. Ideal For: Any Champion air compressor or compatible system using filters P5051A or P05051A, as well as other industrial compressors that require reliable, long-lasting intake filtration in high-demand or dusty environments.
