• 不锈钢4-72A/D型离心通风机

  不锈钢4-72A/D型离心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:本公司号有NO2、2.5、2.8、3.2、3.6、4、4.5、5、5.6、6、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。风机的传动方式为A式。
  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。

• Stainless steel 4-72A/D centrifugal fan

  Stainless steel 4-72A/D centrifugal fan can transport air, non spontaneous gas, harmless gas. and non-corrosive gas Gas does not allow the sticky materian theconcentration of containing dust and nard particles isnot larger than 150mg!m3 The gas temperatureshould not exceed 80℃. The fan is widely used inthe ventilation of industrial and mining enterprises, large bulldings. hotels and other indoor places.
  Product type: The company has NO1, 2.5, 2.8, 3.2, 3.6, 4, 4.5, 5, 5.6, 6, 7.1. It can be made into two types: right-handed and left-handed. The impeller rotates clockwise and is called a right-handed fan. Expressed as "right", the impeller rotates counterclockwise, called the left-handed fan, and is represented by "left". The exit position of the fan is expressed by the air outlet angle of the casing. 4-72(No)2-7.1 is made in various types at the factory, and can be installed to the required position according to the requirements of the unit of use. That is, the position of the air outlet is adjusted from 0° to 225°, and the interval is 22.5° or 45°. There are six types (0°, 45°, 90°, 135°, 180°, 225°). The fan is driven in the A mode. Structural features: The fan is mainly composed of an impeller, a casing, an air inlet, a motor plate and the like with a direct-connected motor. Impeller: consists of 10 rear-tilted airfoil blades, curved front discs and flat rear discs. After dynamic balance correction and aerodynamic performance, it has the characteristics of balanced operation, small vibration, high efficiency and long service life. Housing: welded with a steel plate into a volute casing. Air inlet: made into a whole (all mold molding), installed on the side of the fan, the axially parallel wear surface has no curved shape, which enables the gas to smoothly enter the impeller with less loss.
