Galvanized sheet squaresuction fan The louvers are located at the air outlet, which significantly increases the air resistance. The air does not spread out in all directions, but is guided by the louvers and blown in the same direction. When a person stands in front of the air outlet facing the fan, the air volume on the left side of the fan is significantly greater than that on the right side, which is caused by design defects in the air duct and fan blades& nbsp;
The fiberglass horn shaped negative pressure fan mainly depends on the opening of the louvers and the air outlet of the horn mouth. The louver mainly depends on the opening of the two louvers below. The air outlet from the horn mouth should be the same size for each part, and the air outlet from the center should be the same size as the edge, with the air evenly spreading outwards& nbsp;
The air volume of the fiberglass square negative pressure fan is small. Place the opened fiberglass square negative pressure fan on the ground with the upright frame, and the situation where one side has more wind and the other side has less wind is more obvious than that of the galvanized sheet square negative pressure fan. The fan will rotate clockwise in place.
