The Delta EFB0812EH family table lists a 7.0–13.8 VDC operating range; verify the full supplied fan approval specification for critical equipment.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the fan dimensions?\u003c\/strong\u003e\u003cbr\u003eThe Delta EFB series drawing shows an 80 x 80 x 25.4 mm frame with 71.5 mm mounting-hole pitch and 4.5 mm mounting holes.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eWhy are 0.28 A and 0.42 A both seen for this model family?\u003c\/strong\u003e\u003cbr\u003eAn older Delta EFB0812EH series table gives 0.28 A and 3.36 W, whereas multiple listings for the complete EFB0812EH-F00 fan show 0.42 A. These source-specific values should not be combined or treated as a single independently verified rated current.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eWhat electrical power is associated with EFB0812EH-F00?\u003c\/strong\u003e\u003cbr\u003eAt the seller-listed 12 VDC and 0.42 A, calculated electrical power is 5.04 W. The older Delta EFB0812EH series table lists 3.36 W at 0.28 A; match the printed fan rating when selecting a power source.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the rated rotational speed?\u003c\/strong\u003e\u003cbr\u003eThe Delta EFB0812EH family table and complete-model -F00 product listings both identify 5000 RPM under stated rated-voltage conditions.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the maximum free-air flow?\u003c\/strong\u003e\u003cbr\u003eThe manufacturer EFB series table lists 52.02 CFM (1.473 m³\/min) for EFB0812EH at zero static pressure. Installed flow varies with enclosure resistance.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the maximum static pressure?\u003c\/strong\u003e\u003cbr\u003eThe Delta series table reports 8.94 mmH₂O, approximately 0.352 inH₂O. Some -F00 resellers state 0.392 inH₂O. Use a matching manufacturer performance revision when pressure is a design-critical parameter.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eWhat noise level is listed?\u003c\/strong\u003e\u003cbr\u003eComplete-model -F00 suppliers commonly list 42.5 dB(A). A matching manufacturer approval sheet for this specific suffix was not confirmed for this acoustic value.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eWhat type of bearing does the fan use?\u003c\/strong\u003e\u003cbr\u003eDelta’s EFB 80 x 80 x 25.4 mm series drawing specifies ball bearings and UL 94 V-0 plastic frame and impeller materials.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the -F00 suffix mean, and how is it different from -R00?\u003c\/strong\u003e\u003cbr\u003eIn the Delta EFB series, -F00 designates a frequency or tachometer speed-feedback output, whereas -R00 designates a locked-rotor alarm output. These functions must not be exchanged without checking the equipment signal interface.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eWhat should be checked before ordering EFB0812EH-F00?\u003c\/strong\u003e\u003cbr\u003eVerify the complete EFB0812EH-F00 marking, 12 VDC supply, actual fan-label current, 80 x 80 x 25.4 mm dimensions, mounting hole pattern, 5000 RPM rating, three-wire connector, feedback signal pinout and system airflow requirements.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003c\/main\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"DELTA","offers":[{"title":"Default Title","offer_id":67790804484175,"sku":"LL1-DE-EFB0812EHF00","price":8.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/7569\/2623\/files\/EFB0812EH-F00-01_b68a9518-fe54-4809-aadf-bac48f6357e7.jpg?v=1792402848","url":"https:\/\/yunshuotrade.com\/products\/delta-electronics-efb0812eh-f00-fan","provider":"yunshuotrade","version":"1.0","type":"link"}
