⚡ Energy Savings Through Destratification

Cold Weather:
In tall buildings, temperature rises approximately 0.5°F to 1°F for every foot of height. This means in a 20 ft facility, the ceiling can be 10–20°F hotter than the floor. Bucket Fans push trapped hot air down to floor level, cutting utility bills by 25–33%.

Hot Weather:
In air-conditioned buildings, cold air from ceiling ductwork often gets overwhelmed by rising warm air. Instead of oversizing HVAC systems, Bucket Fans actively push conditioned air downward, improving comfort and saving up to 40% in wasted energy.

Rule of Thumb: For full destratification benefits, turn the air 1–2 times per hour.

📏 Sizing the Right Bucket Fan Whisper

• Ceiling heights 20–30 ft: Use Bucket Fan Whisper 420

• Ceiling heights 25–35 ft: Use Bucket Fan Whisper 1055

• Ceiling heights 30–45 ft: Use Bucket Fan Whisper 1460

Example Calculation:
Building dimensions = 125 ft (L) × 75 ft (W) × 20 ft (H) = 187,500 cu. ft
Formula:

1. H × W × L = Air Volume (V)

2. V ÷ CFM ÷ 60 = Number of Fans

187,500 ÷ 1055 ÷ 60 = 2.96 fans → 3 Bucket Fans required (always round up).
