Awoco 36″ Air Curtain With 2 Speeds
Best for: Entrances in commercial spaces where you need a barrier between interior and exterior air, dust, and drafts without creating indoors cooling. This unit is a powerful fan that forms a high-velocity air stream over doorways, helping to keep interior environments stable during high-traffic periods.

- Magnetic door switch option enables automatic operation when doors are opened or closed; optional if not installed.
- Two speeds: 1177 CFM at high and 942 CFM at low; noise levels are 58dB and 56dB respectively.
- Low power consumption for continuous business hours; designed with German electrical technology.
Best for: Businesses seeking a cost-efficient, low-maintenance air-diversion solution at entry points. Choose this if your goal is to reduce HVAC load by limiting outdoor air infiltration rather than cooling the space directly.
