The Castair ROFD62-P75-P90 is the OEM spin-on oil filter for Castair rotary screw compressors equipped with the D62, P75, or P90 air end. One part number covers three air end variants used across the 15–25 HP range of the Castair rotary screw lineup. If your compressor's service documentation references any of these air ends, this is the correct oil filter. Spin-on design for tool-assisted removal and installation — no housing to open, no element to handle.
