Agrifirst Air Circulation Fan is a horizontal airflow (HAF) fan engineered for continuous air mixing inside polyhouse and greenhouse structures. Without active air circulation, greenhouses develop temperature stratification (hot at top, cool at bottom), humidity pockets (high near plants, low at vent level), and CO₂ depletion zones — all of which reduce crop performance and increase disease risk.
Key Benefits
- Uniform Temperature — Eliminates vertical temperature stratification of up to 8–10°C
- Humidity Control — Continuous air movement prevents moisture buildup on leaf surfaces, reducing Botrytis and mildew by 50–70%
- CO₂ Distribution — Mixes CO₂-rich air from above with the depleted zone around plant leaves
- Energy Efficient — Low wattage motors run 24/7 at minimal electricity cost
- Stronger Stems — Gentle air movement stimulates stem thickening (thigmomorphogenesis)
