Grade Y for the Curtis-Toledo Curtis Toledo Filters line is the fine-stage oil-removal coalescer in a typical compressed-air filtration train, rated to 0.01 micron 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 Curtis-Toledo OEM specification on dimensional fit and filtration outcome, so it slots straight into the genuine Curtis-Toledo housing with no modification. A like-for-like, Australian-stocked replacement at a meaningful saving against the genuine Curtis-Toledo part, with comparable service life and air-quality outcomes.
