How should air ducts be rationally arranged?

The exhaust trajectory of corrosion-resistant fans ensures the circulation of clean air, free from harmful substances. 

Therefore, it is essential to maintain the air pressure, static pressure, and working pressure within the room. Subsequently, the air enters the room via ventilation ducts, return air ducts, or outdoor fresh air system ducts, or is expelled through exhaust ducts designed to sustain working pressure. These requirements must be met upon delivery.

How should corrosion-resistant fan exhaust ducts be rationally arranged? 

Seed sealing performance must achieve Grade A standards. Corrosion-resistant fans may be positioned near mid-to-downstream areas of the building to maintain neutral working pressure and power consumption standards in upstream and downstream ducts. Without precise column-type design, fans positioned close to building sides cannot maintain air pressure, let alone achieve Grade A standards.

Precise window display mode: When the fan is positioned close to the building side, all ducts cannot maintain positive pressure. However, sealing performance achieves Grade A, preventing clean air infiltration.
