Grade A for the Hiross (Zhangzhou) line is the activated-carbon adsorber in a typical compressed-air filtration train, rated to 0.01 micron and works to remove residual oil vapour and hydrocarbon odour after coalescing stages, polishing the compressed air for sensitive end uses. The Ultramax Systems Grade A element is built to match the Hiross 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 Hiross part, with comparable service life and air-quality outcomes.
