变频器原配散热风扇设计寿命25000小时到40000小时,即连续运行3-5年必需更换,否则变频器容量会下降或常常跳闸保护,是因为风扇轴承老化散热能力下降造成的,常常会带来变频器的损坏,有些用户因市场买不到原配高风量风扇而用便宜国产小电流风扇替代更换,风量小且用不了多久便会损坏,直接影响变频器使用寿命.更换时注意风扇的标称电压电流及风量。型号：6250MG12750MTP-15UT626DG-TPUT2760-TP4715KL-05W-B104715KL-05W-B194715KL-05W-B204715KL-05W-B294715KL-05W-B304715KL-05W-B394715KL-05W-B404715KL-05W-B494715KL-05W-***4715KL-05W-B594715MS-20T-***4715MS-22T-***4715MS-23T-***4715MS-24T-***4710PS-20T-B304710PS-22T-B304710PS-23T-B305915PC-20T-B305915PC-22T-B305915PC-23T-B302410ML-04W-B102410ML-04W-B192410ML-04W-B202410ML-04W-B292410ML-04W-B302410ML-04W-B392410ML-04W-B402410ML-04W-B492410ML-04W-***2410ML-04W-B592410ML-04W-B602410ML-04W-B692410ML-04W-B702410ML-04W-B792410ML-04W-B802410ML-04W-B892410ML-05W-B102410ML-05W-B192410ML-05W-B202410ML-05W-B292410ML-05W-B302410ML-05W-B392410ML-05W-B402410ML-05W-B492410ML-05W-***2410ML-05W-B592410ML-05W-B602410ML-05W-B692410ML-05W-B702410ML-05W-B793110KL-05W-B103110KL-05W-B193110KL-05W-B203110KL-05W-B293110KL-05W-B303110KL-05W-B393110KL-05W-B403110KL-05W-B493110KL-05W-***3110KL-05W-B593110KL-05W-B603110KL-05W-B693610KL-04W-B103610KL-04W-B193610KL-04W-B203610KL-04W-B293610KL-04W-B303610KL-04W-B393610KL-04W-B403610KL-04W-B493610KL-04W-***3610KL-04W-B593610KL-04W-B603610KL-04W-B693610KL-05W-B103610KL-05W-B193610KL-05W-B203610KL-05W-B293610KL-05W-B303610KL-05W-B393610KL-05W-B403610KL-05W-B493610KL-05W-***3610KL-05W-B593610KL-05W-B603610KL-05W-B69)
