Classification and selection strategies of explosion-proof fans

If you want to know about explosion-proof fans, then let's take a look at what the relevant people have to say: 1. Main classification By function: They are classified into axial flow fans (such as the BT35 series), centrifugal fans (such as the BF1200 type), and smoke exhaust fans (such as the BPF1000 type). By explosion-proof grade: ExdIIBT4 (temperature resistance 135℃), ExdIICT6 (temperature resistance 85℃), applicable to different gas groups. 2. Scene adaptation suggestions Chemical reaction vessel: It is required to be ExdIICT6 explosion-proof and made of corrosion-resistant materials (such as 316L stainless steel). Grain storage: Select all-aluminum lightweight roof fans to reduce the load-bearing pressure on the structure.
