The Domnick Hunter PISOILX DHEX is part of the Domnick Hunter compressed-air filtration lineup, a long-established compressed-air filtration brand (now Parker Domnick Hunter). 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 PISOILX DHEX line, built to match the Domnick Hunter 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 Domnick Hunter, with comparable service life and air-quality outcomes.
