This Grade Y element fits the On Site Gases platform and acts as the fine-stage oil-removal coalescer of a typical compressed-air filtration train — — working 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 OEM specification on dimensional fit and filtration outcome, so it slots straight into the original On Site Gases housing with no modification. A like-for-like, Australian-stocked replacement at a meaningful saving against the genuine OEM part, with comparable service life and air-quality outcomes.
