The Sullair Oil X is part of the Sullair compressed-air lineup, a long-established rotary-screw compressor line. It is deployed across Australian mining, process and heavy-industry operations, with scheduled inline filter element changes essential to maintain rated air quality. Ultramax Systems stocks alternative-line and original-line replacement elements for the Oil X line, built to match the Sullair OEM specification on dimensional fit and filtration outcome across the standard P, X, Y and A grades. Select by grade below for a like-for-like replacement at a noticeably better landed cost than ordering direct through Sullair, with comparable service life and air-quality outcomes.
