The three-blade -R00 version is separately listed at 3100 RPM and approximately 105.0 CFM.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the maximum static pressure of 4715KL-07W-B30?\u003c\/strong\u003e\u003cbr\u003eThe manufacturer specifies 68.1 Pa, approximately 0.27 inches of water, for the standard -P00 and -E00 configurations. The separate -R00 version is listed at 74.0 Pa. Maximum airflow and maximum static pressure represent different points on the fan's performance curve and do not occur simultaneously.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the noise level of 4715KL-07W-B30?\u003c\/strong\u003e\u003cbr\u003eNMB specifies 42.5 dB for the standard B30 -P00 and -E00 versions. The separately documented three-blade -R00 version is listed at 47.0 dB. Actual installed noise may differ due to mounting, vibration, enclosure construction and airflow resistance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat bearing type does 4715KL-07W-B30 use?\u003c\/strong\u003e\u003cbr\u003eThe documented standard models use ball bearings. The manufacturer specifies an L10 expected life of 100,000 hours at 25°C for these models. L10 life is a statistical bearing-life measure under defined operating conditions, not a guaranteed lifetime for every individual fan.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes 4715KL-07W-B30 have two wires?\u003c\/strong\u003e\u003cbr\u003eYes. The standard manufacturer-documented -P00 and -E00 configurations use two DC power leads. The series datasheet identifies red as the positive supply wire and black as the negative wire, with UL1007 AWG24 leads. These standard versions do not provide separate tachometer, locked-rotor or dedicated PWM control conductors.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between 4715KL-07W-B30-P00 and 4715KL-07W-B30-R00?\u003c\/strong\u003e\u003cbr\u003eThe -P00 is a standard flange-type fan rated at 48 VDC, 0.16 A, 2950 RPM, 108.4 CFM, 68.1 Pa and 42.5 dB. The -R00 is a separately documented three-blade configuration rated at 48 VDC, 0.13 A, 3100 RPM, 105.0 CFM, 74.0 Pa and 47.0 dB. These versions differ in blade construction, electrical power and airflow characteristics, so they should not be assumed performance-identical or directly interchangeable.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs NMB-MAT 4715KL-07W-B30 discontinued, and what is its replacement?\u003c\/strong\u003e\u003cbr\u003eNMB identifies the documented standard -P00 and -E00 models as legacy part numbers with a manufacturer part-number change and does not recommend them for new designs. DigiKey lists these legacy configurations as obsolete. The manufacturer identifies 11938KA-48L-EA-00 as their replacement, describing it as an identical fan under a new part number. A verified direct replacement for the separate three-blade -R00 configuration has not been established.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat should be checked before ordering 4715KL-07W-B30?\u003c\/strong\u003e\u003cbr\u003eConfirm the complete model number 4715KL-07W-B30 and additional -P00, -E00 or -R00 suffix; nominal 48 VDC supply; 25.0–55.2 VDC operating range; rated current and input power; 119 × 119 × 38 mm frame; mounting dimensions; fan speed; airflow; static pressure; noise rating; ball bearing construction for the standard models; wire count; connector or lead termination; rotation and airflow direction; and equipment compatibility. For standard -P00 and -E00 replacement applications, review the manufacturer-listed 11938KA-48L-EA-00. Do not apply the standard model specifications or replacement reference automatically to the different three-blade -R00 assembly.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003c\/main\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"NMB","offers":[{"title":"Default Title","offer_id":67750361432143,"sku":"LL1-NMB-4715KL07WB30","price":15.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/7569\/2623\/files\/4715KL-07W-B30-01_fb5698fe-406a-4434-82bd-a8b8fea1981e.jpg?v=1792208948","url":"https:\/\/yunshuotrade.com\/products\/nmb-mat-4715kl-07w-b30-dc-axial-fan","provider":"yunshuotrade","version":"1.0","type":"link"}
