1. Product Story: Technology Empowering Green Breathing

2. Pain Points: Four Major “Suffocation Syndromes” of Traditional Fans
Energy Drain
Traditional AC fans are “energy vampires,” devouring hundreds of dollars in electricity each month.
Noise Pollution
Loud operation comparable to busy streets. Night operation leads to complaints? Home growing becomes a noise disturbance.
Maintenance Nightmare
Frequent cleaning and lubrication needs, skyrocketing labor costs, eroding your enthusiasm for growing.
Temperature Imbalance
Uneven ventilation causes root rot and yellowing leaves, with both yield and quality plummeting!

Noise Level | 65dB+ (Roaring) | ≤45dB (Whisper-quiet) |
Maintenance Frequency | 2-3 times monthly | 1-2 times yearly |
