How it works

  1. 1ACH method: airflow = area × height × air changes (60 h⁻¹)
  2. 28 × 2.7 × 60 ≈ 1,296 m³/h
  3. 3= 21.6 m³/min, inside the 20-22 m³/min band

Shanghai market regulator bands: light 18-20 m³/min, daily stir-fry 20-22, heavy wok or big kitchens 22-24. The 10 m³/min national minimum is only a floor.

Add 10%~15% airflow if the duct exceeds 3 m or has two or more bends; keep ducts short and straight.

Pick ≤65 dB at max speed. Side-draft hoods sit 25-40 cm above the cooktop; canopy hoods 65-75 cm. Clean filters monthly.
