Silent Killer in Your Ducts: Why Fresh Air Flow Drops 50% After 2 Years (With Proof)!

Case Study:

Real-world example: Ventilation capacity fell from 300m³/h to 150m³/h in 24 months.

Endoscope footage: 3mm dust layer inside ducts increases air resistance by 280%.

Technical Deep Dive:

① Mismatched filter grades (Why MERV 8+G4 combo works best).

② Poor duct layout design (CFD simulation of U-shaped vs straight duct airflow).

③ Clogged heat exchanger cores (Thermal imaging reveals blockage hotspots).

Innovative Fixes:

✅ Anti-static duct coating technology (Reduces dust adhesion by 70%).

✅ Self-cleaning duct system demo video (Highlight patented airflow pulsation tech).
