The D6 air end is found in Castair's 15–20 HP rotary screw models — mid-range machines that deliver 52–80 CFM at 100 PSI in continuous-duty operation. The ROFD6 is a spin-on automotive-style filter, the same format Castair uses across their rotary screw line for ease of service without specialized tools or housing disassembly.\u003c\/p\u003e\n\n\u003ch2\u003eD6 Air End Applications\u003c\/h2\u003e\n\u003cp\u003eThe D6 air end is used in Castair rotary screw models in the 15–20 HP class. These include machines in the R15 and R20 series equipped with the D6 (as opposed to G30) air end. If your model designation includes D6 or your service documentation references the D6 air end, this is the correct oil filter. If your 15–20 HP Castair uses a G30 air end instead, use the ROFD16-G30 filter.\u003c\/p\u003e\n\n\u003ch2\u003eMaintenance Context\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter type:\u003c\/strong\u003e Spin-on oil filter, automotive paper element design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaintenance kit:\u003c\/strong\u003e \u003cstrong\u003eMKD6\u003c\/strong\u003e — for D6 air end: 2 air filters (RAFD6-62), 4 oil filters (ROFD6), 1 separator filter (RSFD3-4-6-G11-P75), 5 gallons synthetic Cast-Lube oil — 10% savings vs. individual purchase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible oil:\u003c\/strong\u003e GA4000 or FG4000 Castair synthetic rotary screw lubricant (1 year\/4,000 hour rating)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService interval:\u003c\/strong\u003e Replace with each scheduled oil change; track via the standard hour meter on all Castair rotary units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir filter for D6:\u003c\/strong\u003e RAFD6-62 — paper element, ID: 4-3\/4\", OD: 6-1\/8\", HGT: 2-7\/8\" (also fits D62)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy Use OEM Filters\u003c\/h2\u003e\n\u003cp\u003eCastair designs their rotary screw compressors around off-the-shelf, serviceable components. The ROFD6 spin-on filter uses the correct bypass valve rating, correct thread specification, and correct media density for the D6 oil circuit. An aftermarket substitute with a different bypass rating can allow unfiltered oil circulation at low temperatures or under high-differential pressure conditions — exactly when you need filtration most.
