Campbell Hausfeld ST073903AV Paper Air Filter Element

Campbell Hausfeld ST073903AV is a 4-micron paper air filter element designed to shield Campbell Hausfeld air compressors from dust and particulates at the intake. It measures 4-3/8 inches in outer diameter, 3 inches in inner diameter, and stands 2-3/8 inches tall, and it fits in compatible air-filter housings that specify the ST073903AV part. This official replacement filter element, built from paper filtration media, is intended for single-use replacement during routine maintenance to maintain clean intake air and protect the pump’s internal components. By capturing fine particles before they enter the compression chamber, it helps sustain compressor performance and longevity in Campbell Hausfeld models that rely on this exact element. Regular replacement of ST073903AV ensures consistent airflow, reduces wear from contaminants, and supports reliable operation of the configured Campbell Hausfeld air system.
