4-72-3.6A-1.1Kw不锈钢通风机

4-72A型不锈钢通风机 4-72A型不锈钢通风机可输送空气和其他不自燃的、对人体无害的、对钢材无腐蚀性的气体。气体内不允许有粘性物质，所含尘土及硬质颗粒物不大于150mg/m。气体温度不得超过80℃。该风机广泛适用于工矿企业、大型建筑物、宾馆酒楼等室内通风换气排烟。
产品型式:该风机为A式传动：风机无附加轴承支承，叶轮与电机直联传动。机号有NO2.5、2.8、3.2、3.6、4、4.5、5、5.6、6、6.3、7.1十一种。可制成右旋和左旋两种型式，叶轮顺时针旋转，称为右旋风机。以“右”表示，叶轮逆时针旋转，称为左旋风机，以“左”表示。风机的出口位置，以机壳的出风角度表示。4-72(No)2-7.1出厂时均做成多种型式，可根据使用单位要求安装成所需的位置，即出风口位置调整范围0°~225°间隔是22.5°或45°，即（0°、45°、90°、135°、180°、225°）共六种，用户根据需求制成一种方向角度。
结构特点:本风机主要由叶轮、机壳、进风口、电机板等配直连电动机而组成。叶轮：由10个后倾斜的机翼型叶片、曲线型前盘和平板后盘组成。并经过动平衡校正，气动性能，故运转平衡、振动小、效率高、寿命长等特点。机壳：用钢板焊成蜗型壳体。进风口：制成整体（全部模具成型），装于风机的侧面，于轴向平行的戴面未曲线形状，能使气体顺利进入叶轮，且损失较小。

4-72A Stainless steel fan 4-72A Stainless steel fan It can transport air and other non-flammable harmless to human body and non-corrosive gas to steel. No viscous substances are allowed in the gas. Dust and hard particulate matter should not be greater than 150mg/m. The gas temperature shall not exceed 80℃. The fan is widely used in industrial and mining enterprises large buildings hotels restaurants and other indoor ventilation.
Product type: The fan is A type drive: the fan has no additional bearing support and the impeller is directly driven with the motor. There are 11 kinds of machine numbers: NO2.5, 2.8, 3.2, 3.6, 4, 4.5, 5, 5.6, 6, 6.3 and 7.1. Can be made into right-handed and left-handed two types the impeller rotating clockwise called right-handed fan. In & other; Right & throughout; That the impeller rotates counterclockwise called the left cyclone to “ Left & throughout; Said. The outlet position of the fan is expressed by the outlet Angle of the enclosure. 4-72(No)2-7.1 factory are made into a variety of types according to the requirements of the unit installed into the required position that is the outlet position adjustment range of 0° ~ 225° Or 45° that is, (0°, 45°, 90°, 135°, 180°, 225°) a total of six the user makes a direction Angle according to the demand.
Structure features: The fan is mainly composed of impeller housing air inlet motor plate and other directly connected to the motor. Impeller: consists of 10 rear sloped airfoil blades curved front disc and flat rear disc. And after dynamic balance correction pneumatic performance so the operation balance small vibration high efficiency long life and other characteristics. Housing: welded with steel plate into a cochlear housing. Air INLET: MADE INTO a WHOLE (all mold molding) installed on the side of the fan parallel to the axial surface without curve shape can make the gas smoothly into the impeller and the loss is small.
