Pros
- 25,000 CFM, the most airflow here, from a standard 120 V outlet
- Covers up to 8,500 sq ft, so one unit can replace several smaller coolers
- App control with schedules and alerts
- A 66 gallon tank plus hose hookup
Cons
- Draws 14.7 A, so it needs a dedicated 15 or 20 A circuit to itself
- At 290 lb and 90 in tall it is a forklift or ramp job in tight spaces
- Loud at 68 dB
