The Riako Gen 1 is one of the Riako Gen compressed-air lines used across Australian mining, process and heavy-industry operations, with scheduled inline filter element changes essential to preserve rated air quality. Ultramax Systems stocks alternative-line and original-line replacement elements for the 1 line, built to match the Riako Gen OEM specification on dimensional fit and filtration outcome across the standard P, X, Y and A grades. Select by grade below for a like-for-like replacement at a noticeably better landed cost than ordering direct through Riako Gen, with comparable service life and air-quality outcomes.
