DH Maxi & MPlus PCO2 is a Domnick Hunter compressed-air filtration platform used across Australian workshops, light manufacturing and food-grade installations. Domnick Hunter is a long-established compressed-air filtration brand (now Parker Domnick Hunter), and scheduled inline filter changes are essential to maintain compressed-air quality and protect downstream pneumatic equipment. Ultramax Systems stocks replacement and original-line filter elements that fit the full DH Maxi & MPlus PCO2 range, built to match the Domnick Hunter OEM part on dimensional fit and filtration performance and covering the standard P, X, Y and A coalescing and adsorption grades. A cost-effective like-for-like alternative to ordering direct through Domnick Hunter, stocked in Australia with full traceability and supported by our local technical team.
