The 490R-RAC-01 features a high capacity Aquabloc II filter element that removes sediment down to 10 micron. The spin-on filter design is simple to replace and the reusable, see-thru contaminant collection bowl features a self-venting drain for removing unwanted solids and water. The mounting head is anodized and coated with a durable electrostatically applied white powder coating for superior corrosion resistance. That’s the quality you’ve learned to expect from Racor.
