Large industrial negative pressure fan

The industrial negative pressure fan represents a novel type of ventilation fan, specifically an axial flow fan. Due to its primary application in negative pressure ventilation and cooling engineering, it is commonly referred to as a negative pressure fan. This type of fan addresses both ventilation and cooling needs, offering a comprehensive solution for these two aspects. Additionally, negative pressure fans find applications in positive pressure water curtain environmental air conditioning, positive pressure air supply, positive pressure air blowing, and other related fields. Key features of the negative pressure fan include a large capacity, extensive air duct, large blade diameter, high exhaust volume, low energy consumption, slow rotational speed, and minimal noise. Structurally, these fans are primarily categorized into two types: galvanized sheet square negative pressure fans and fiberglass horn negative pressure fans.
