Its aluminum flexible blades, finished in blue, flatten out as engine rpm rises to reduce the power the fan draws at speed while still moving strong airflow at idle and low speeds. The fan uses a black hub and turns in the standard clockwise rotation used by most V-belt and serpentine water pump setups.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: Belt-driven flex fan\u003c\/li\u003e\n\u003cli\u003eDiameter: 17\"\u003c\/li\u003e\n\u003cli\u003eBlade material: Aluminum\u003c\/li\u003e\n\u003cli\u003eBlade color: Blue\u003c\/li\u003e\n\u003cli\u003eBlade style: Flexible (flex) blades\u003c\/li\u003e\n\u003cli\u003eHub color: Black\u003c\/li\u003e\n\u003cli\u003eRotation: Standard rotation (clockwise)\u003c\/li\u003e\n\u003cli\u003ePart number: 19917\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat size is the Derale 19917 flex fan?\u003c\/h5\u003e\u003cp\u003eIt is 17 inches in diameter.\u003c\/p\u003e\u003ch5\u003eWhat are the blades made of?\u003c\/h5\u003e\u003cp\u003eThey are aluminum flexible flex blades finished in blue.\u003c\/p\u003e\u003ch5\u003eWhich rotation is this fan?\u003c\/h5\u003e\u003cp\u003eIt is standard rotation, turning clockwise, for common belt-driven water pumps.\u003c\/p\u003e\u003ch5\u003eWhy choose a flex fan?\u003c\/h5\u003e\u003cp\u003eThe flexible blades flatten at higher rpm to cut drag and noise while still cooling at idle and low speed.\u003c\/p\u003e\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What size is the Derale 19917 flex fan?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"It is 17 inches in diameter.\"}}, {\"@type\": \"Question\", \"name\": \"What are the blades made of?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"They are aluminum flexible flex blades finished in blue.\"}}, {\"@type\": \"Question\", \"name\": \"Which rotation is this fan?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"It is standard rotation, turning clockwise, for common belt-driven water pumps.\"}}, {\"@type\": \"Question\", \"name\": \"Why choose a flex fan?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The flexible blades flatten at higher rpm to cut drag and noise while still cooling at idle and low speed.\"}}]}\u003c\/script\u003e","brand":"Derale","offers":[{"title":"Default Title","offer_id":41287448166448,"sku":"BDST_19917","price":54.49,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0586\/9548\/3440\/files\/DER19917.jpg?v=1712607893","url":"https:\/\/berryperformancesales.com\/products\/17in-aluminum-standard-rotation-flex-fan-blue-blade-black-hub-19917","provider":"Berry Performance Sales","version":"1.0","type":"link"}
