It fits inline in the intake path to trap airborne dirt and debris before they reach the engine, protecting internal components and helping maintain steady generator performance in the marine environment. The filter is built as a direct replacement for the original Westerbeke 39705 filter, so it installs using the same mounting configuration as the part it replaces, with no modification needed.\u003c\/p\u003e\u003cp\u003eThis filter is intended for Westerbeke generator models rated 8.0 BTDA, 10.0 BTDA, 12.5 BTDB, and 15.0 BTDC (at both 50Hz and 60Hz operation), covering a common range of onboard generator output classes. Each unit ships as a single filter (quantity of one) and is backed by Sierra's standard customer satisfaction warranty covering defects in workmanship and materials.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 223-1101\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Air Filter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Westerbeke Generator Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 39705\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.8 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eWesterbeke 8.0 BTDA (60Hz) \/ 6.0 BTDA (50Hz)\u003c\/li\u003e\n\u003cli\u003eWesterbeke 10.0 BTDA (60Hz) \/ 7.5 BTDA (50Hz)\u003c\/li\u003e\n\u003cli\u003eWesterbeke 12.5 BTDB (60Hz) \/ 9.4 BTDB (50Hz)\u003c\/li\u003e\n\u003cli\u003eWesterbeke 15.0 BTDC (60Hz) \/ 12.0 BTDC (50Hz)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e39705\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 223-1101 air filter fit?\u003c\/strong\u003e The Sierra 223-1101 air filter is designed for Westerbeke generators rated 8.0 BTDA, 10.0 BTDA, 12.5 BTDB, and 15.0 BTDC, at both 50Hz and 60Hz operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 223-1101 the same as OEM part 39705?\u003c\/strong\u003e Yes, the Sierra 223-1101 is a direct replacement for the original Westerbeke 39705 air filter and installs in the same location without modification.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many filters come in a package?\u003c\/strong\u003e Each Sierra 223-1101 order includes one air filter (quantity of one).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the air filter weigh?\u003c\/strong\u003e The Sierra 223-1101 air filter weighs 0.8 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this filter work on 50Hz generator models?\u003c\/strong\u003e Yes, the 223-1101 covers both 50Hz and 60Hz versions of the listed Westerbeke BTDA, BTDB, and BTDC generator models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes Sierra offer a warranty on this air filter?\u003c\/strong\u003e The Sierra 223-1101 is covered under Sierra's customer satisfaction warranty, which covers defects in workmanship and materials for the useful life of the product.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this filter be used as a genuine OEM replacement rather than an aftermarket substitute?\u003c\/strong\u003e The 223-1101 is manufactured by Sierra as a replacement part designed to meet or exceed the performance of the original Westerbeke 39705 filter it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat generator series is compatible with part number 223-1101?\u003c\/strong\u003e Part number 223-1101 is compatible with Westerbeke's BTDA, BTDB, and BTDC generator series at the specific ratings of 8.0, 10.0, 12.5, and 15.0 (60Hz) or their corresponding 50Hz ratings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs installation of the 223-1101 straightforward?\u003c\/strong\u003e Because the Sierra 223-1101 is a direct replacement for the Westerbeke 39705, it fits the original filter housing without requiring any additional parts or modification.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM number should I search if I only have my old filter's part number?\u003c\/strong\u003e If your old Westerbeke generator filter is marked 39705, the Sierra 223-1101 is the replacement to order.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988447178971,"sku":"SIE-23-1101","price":8.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-23-1101__36232.1558187267.500.750.jpg?v=1785188525","url":"https:\/\/www.goodvibesmarina.com\/products\/air-filter-for-westerbeke-btd-marine-generators-replaces-39705-sierra-23-1101","provider":"Good Vibes Marina","version":"1.0","type":"link"}
