The Grade YSR Stainless Sterile Coalescer 0.01 Micron is part of the Ultramax Systems alternative-line filtration range for the Ateliers Francois AF platform. This element is built to match the Ateliers 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 Ateliers, with comparable service life to the genuine part.
