In our plant have install Motor Ex explosion proof model M3KP for 5 years, most common problem are the plastic cooling fans are always broken, then we ask for upgrade the material by question as are follows;
1. For M3KP, can this Ex motor fit with "Light alloy metal fan", option code 068? 2. How about "Siluminium fan", what the material made? 3. How differenct between "Light alloy metal fan" versus "Siluminium fan" ?
