Detailed Description
Axial fan "Axipal "FTDA-P is a modern industry original fan. He used to smoke protection of buildings, when you need to create a positive pressure air into the premises for evacuation in case of fire in elevator shafts, locks, on nezadymlyaemyh stairwells. The main advantages of the fan are high efficiency, low noise, the possibility of accurate selection of electric motor power the fan on the set parameters, which leads to energy savings.
Design features
Housing, Engine mount, bracket and semi holder impeller made of sheet steel. The originality of the body is that it directly unbent flanges at both ends of the cylinder on a special machine. This results in sizing the inner diameter of the body and a significant increase in its rigidity. The calibrated internal diameter of the shell allows to minimize the gap between the outer diameter of the impeller and the inner surface of the housing wall and thus reduce the pressure loss in the fan.
In addition, the increased rigidity of the body leads to a significant reduction of vibration and the overall level of fan noise. Bulk aerodynamic blades are cast from aluminum alloy. The impeller has six blades. The factory is possible to install a fixed angle of impeller blades in a range from 7 to 37 degrees, which allows us to obtain the optimal performance of the fan for the specific operating conditions.
Application of the diffuser reduces the dynamic pressure of the fan and the increase in the static part of the total pressure developed by fan. To improve the aerodynamic parameters of air flow in the free fan inlet is recommended to set the input cone FTDZ-31. The fan is designed for operation in the macro-climate regions with temperate climates (version I), allocation category 2, 3 and 4 according to GOST 15150-69. Medium temperatures of -40 ° C to + 40 ° C.
