The Activated Carbon is part of the Ultramax Systems alternative-line filtration range for the Mark F platform. This element is built to match the Mark OEM specification on dimensional fit and filtration outcome, so it installs into the original housing with no modification and delivers comparable air-quality performance across the service interval. Stocked in Australia, fully traceable, and supplied as a like-for-like replacement at a noticeable saving against ordering through Mark, with comparable service life to the genuine part.
