1、 Usage: DT40-12 and BDT40-12 low-noise fans are both roof axial flow fans, which can be used for ventilation and exhaust in departments such as petroleum, metallurgy, and machinery, as well as for indoor ventilation and exhaust in general factories, warehouses, and large buildings.
2、 Type: BDT40 roof axial fan is explosion-proof. The impeller is made of steel plate, and there is an aluminum lining plate inside the air duct. The body is coated with anti-corrosion protective paint, so the fan has a certain degree of corrosion resistance. The DT40 roof axial flow fan can transport general gases.
All products adopt a direct connection structure where the impeller is directly mounted on the motor shaft. Under the condition that the circumferential speed of the impeller does not exceed 60m/s, two speeds are used: 1450 and 960r/min. The impeller rotates counterclockwise when facing the air inlet direction.
3、 Structure: This fan is mainly composed of four parts: impeller, casing, collector, and rain cover.
4、 Performance parameter table of DT40-12 and BDT40-12 roof axial flow fans
The parameters provided in the performance table, unless otherwise specified, are calculated based on the standard inlet state of the fan, which is the standard state of air medium, pressure of 101325Pa, temperature of 20 ℃, density of 1.2kg/m3, and relative humidity of 50%.
