Purpose
Type 4-68 centrifugal fans are generally used for ventilation in factories and large buildings. They can be used for both intake and exhaust of gases. This fan can transport air or other non-combustible, non-explosive, non-volatile gases that are harmless to humans and non-corrosive to steel. The gas must not contain viscous substances, and the content of dust and hard particles must not exceed 150mg/m³ 3 The gas temperature must not exceed 80℃.
Type
This fan is usually made as a single-suction type, with model numbers: N2.8, 3.15, 3.55, 4, 4.5, 5, 6.3, 8, 10, 12.5, 16, 20 (twelve model numbers in total).
The fan can be manufactured in two types: clockwise and counterclockwise. Viewed from the motor end, the impeller rotating clockwise is called a clockwise fan, indicated by "right"; otherwise, it is a counterclockwise fan, indicated by "left". The fan outlet position is indicated by the angle of the casing outlet. Both "left" and "right" can be manufactured at 0°, 45°, 90°, 135°, 180°, 225°.
The fan has four transmission methods: A, B, C, and D. 2.8~5 adopts type A, which is direct motor connection. The impeller and casing of the fan are directly fixed to the motor shaft and flange (using B35 motor). 6.3~12.5 adopts cantilever support, which is further divided into type C (belt drive, pulley on the outside of the bearing) and type D (using a coupling for transmission). 16 and 20 use type B cantilever support, belt drive, with the pulley in the middle of the bearing.
