This Grade P element fits the Active Air Spares platform and acts as the first-stage general-purpose coalescer of a typical compressed-air filtration train — rated to 3 micron — working to strip bulk liquid water, oil aerosol and solid particulate so finer downstream stages aren't loaded prematurely. The Ultramax Systems Grade P element is built to match the Active Air OEM specification on dimensional fit and filtration outcome, so it slots straight into the original housing with no modification. A like-for-like, Australian-stocked replacement at a meaningful saving against the genuine Active Air part, with comparable service life and air-quality outcomes.
