Grade Y for the SWAN (Taiwan) Swan Taiwan - New Series line is the fine-stage oil-removal coalescer in a typical compressed-air filtration train, and works to reduce residual oil aerosol carryover to a level suitable for sensitive downstream equipment, instrumentation and end-product contact. The Ultramax Systems Grade Y element is built to match the SWAN (Taiwan) OEM specification on dimensional fit and filtration outcome, so it slots straight into the genuine SWAN (Taiwan) housing with no modification. A like-for-like, Australian-stocked replacement at a meaningful saving against the genuine SWAN (Taiwan) part, with comparable service life and air-quality outcomes.
