In addition, this fan can also handle corrosive gases. No viscous substances are allowed in the treated gas, and the content of dust and hard particles in the gas is not more than 150 mg / m 3 . The gas temperature must not exceed 80 °C.
Product description

Product introduction:

This high flow low pressure fan can be used to ventilate or transport air and other non-natural, non-explosive, non-volatile, non-hazardous gases in general factories and large building rooms. In addition, this fan can also handle corrosive gases. No viscous substances are allowed in the treated gas, and the content of dust and hard particles in the gas is not more than 150 mg / m 3 . The gas temperature must not exceed 80 °C.

Product features:

1. This high flow low pressure fan is made of stainless steel, glass fiber reinforced plastic or other corrosion resistant materials. Its performance and basic dimensions are the same as those of the 4-72 centrifugal fan. The position of the air outlet of the fan can be expressed from the exit angle of the outer casing. No.2.8~6 is an angle of 0°. The user can change the angle according to the need, and no need to pay attention when ordering. Among them, the angle of the angle of No2.8~6 is adjusted to 0°~225°, and the interval is 45°; the No3.2~6 outlets are 0°~225°, the interval is 22.5°, and the No8~12 exit angles are adjusted to 0 ° ~ 225 °, the interval is 45 °; For No16, 20 angle adjustment can be made 0 °, 90 °, 180 ° three angles, can not be adjusted, pay attention when ordering.

2. It has 4 drive modes: A, B, C, D: In 4-72 fan, No2. If the above machine No, drive mode and exit angle can not meet your requirements, our factory has the ability to transform and design the fan for you until you are satisfied. This high flow low pressure fan is mainly composed of impeller, casing, air inlet and motor. No6C and No8~20 except the drive unit, except for the above structure. The impeller consists of 10 rear wing blades, a curved front plate and a flat rear plate, which are made of steel sheet (B4-72 impeller made of cast aluminum alloy). The impeller is subjected to an overspeed test to ensure smooth operation and good aerodynamic performance.

3. Its casing is divided into two different types. No. 2.8~12 casing is integral and cannot be decomposed. The No16~20 casing is made of three-open type, and the outer casing is divided into two parts along the dividing horizontal plane. The upper casing is vertically divided into two parts along the center line and fixed by bolts, so that the impeller can be easily inserted or taken out.

4. The inlet is monolithic, the inlet is usually fixed to the side of the fan, and the portion parallel to the shaft is in the form of a bend. The gas can enter the impeller smoothly and the loss is small. The drive consists of a shaft, bearing housing, rolling bearing, pulley or coupling.
