One kit covers both models — the internal components are identical. Queenaire recommends annual replacement to maintain rated ozone output and extend unit service life.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's in the RAKIT52-II\u003c\/h3\u003e\n\u003cp\u003eThe kit includes replacement ceramic ozone plates, the corona discharge electrode assembly, and any secondary wear components specific to the Series II chassis. These are OEM parts — not aftermarket substitutes — machined and spec'd to the same tolerances as the original factory build. Installation follows the Series II maintenance guide included with the unit: power off, access panel removal, plate assembly swap. No tools beyond a screwdriver required.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eRAKIT52-II\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCompatible Units\u003c\/td\u003e\n\u003ctd\u003eRainbowair 5210-II (250), 5200-II (500)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eReplacement Interval\u003c\/td\u003e\n\u003ctd\u003eAnnually or every 500 operating hours\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eContents\u003c\/td\u003e\n\u003ctd\u003eOEM ceramic plates, electrode assembly, wear components\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhen to Replace\u003c\/h3\u003e\n\u003cp\u003eAnnual replacement is the standard maintenance interval. If ozone concentration in treatment areas is visibly declining — longer sessions needed for the same result, or detectable ozone smell not building up as expected — the plates are degrading early. High-frequency use environments (daily commercial restoration use) may require replacement at 6–9 months instead of annually. Keep a kit on hand to eliminate downtime between jobs.\u003c\/p\u003e","brand":"Rainbowair","offers":[{"title":"Default Title","offer_id":47743861588125,"sku":"RAKIT52-II","price":79.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0651\/8112\/2717\/files\/rainbowair-activator-250-and-500-maintenance-kit-for-5210-ii-and-5200-ii-rakit-52-ii__15430.webp?v=1774043126","url":"https:\/\/uscleaningtools.com\/products\/rainbowair-activator-250-500-series-ii-maintenance-kit","provider":"US Cleaning Tools","version":"1.0","type":"link"}
