厂里买了一台据说是防爆风扇，用于喷漆房（2区），可怎么鉴定它确实是防爆的，类型和等级？主要看它的防爆标志 订购热线——189 6776 7601首先防爆电器以Ex开头，然后是它的防爆型式，一般有d隔爆型，e增安型，m浇封型，ia或ib为本质安全型，q为充砂型，o为油浸型等等，然后是I代表矿用，II代表厂用，接着是T1-T6中的一个，代表温度组别，如果是隔爆或者本安型还要细分为A,B,C三种型号。
举个例子：ExedIIBT4，代表防爆电器为增安、隔爆复合型B等级，厂用，符合T4温度组别。
你所说的防爆风扇一般是隔爆的T1-T6指最高表面温度T6不高于85，T5不高于100，T4不高于135，T3不高于200，T2不高于300，T1不高于450防爆风扇的作用把烟雾迅速地排除，防止发生恶性事故产品型号叶轮直径（mm）叶轮转速（m/s）叶轮角度风量（m 3 /h）风压（pa）电机功率（KW）重量（Kg）BT35-11-2.828029001516491520.1215.5202167169152526851740.183029211863532022320.2517145015826380.02514.52010864325134644301464480.0435160560BT35-11-3.1531529001523391920.18182030742140.25192538102200.37203044142373545452940.551450151169480.02521.5201537530.0416.525190555302072590.0617352273740.09BT35-11-3.5535529001533672410.37242044262720.5525.52554842793059653000.75263565423731.1291450151680610.0420.5202208680.0621252737700.0930326575353977930.1222BT35-11-440029001548063100.5529.52063163451.1332578263543085133803593364741.5381450152406770.0925203163860.122625392088304263950.18273546871190.2528BT35-11-4.54501450153427980.12282045041100.18292558811130.25303060701210.3731356658150BT35-11-550014501547001220.25382061781350.37392576551383078131490.55413588321850.75441450153314530.374420412959255117613055666535610481BT35-11-5.656014501565951510.37502086671690.555225107391740.755530116821861.1593512812232960154362670.3753205730742571017630772481358471101BT35-11-6.363014501593931920.757120123452141.17525152972201.578301663923635182502942.292960156219840.37692081739425101289630110161040.7574.53512082128BT35-11-7.1710145015134442441.58820176702722.2102252189527930238153003106352612037341119601589021080.7584.520117001202514498123301576913135172961641.187.5BT35-11-8800145015192353102.212520252803454134253132535430340733805.515935370704747.517296015127331360.75107.520167331511.1110.525207351551.5124302255616735247392082.2136BT35-11-990096015181321721.515520238301912.216725295291963185303211921135352272634195BT35-11-10100096015248742132.21982032691236321625405082424226304406226135483263247.5283BT35-11-11.211209601534944267426520459272975.527625569093047.53223061091337356789240711352
