The Hurricane Pro High Velocity Oscillating Metal Wall Mount Fan 20" is an all‑metal, heavy‑duty wall fan designed for continuous air movement in greenhouses, grow rooms, garages, gyms, and workshops. It uses a 20‑inch (50.8 cm) aluminum blade set within a powder‑coated steel housing. The 3‑speed motor delivers up to 4,500 CFM (≈7,646 m³/h) at about 1,450 RPM and draws around 140 W on 120 V. Oscillation and adjustable tilt allow precise airflow direction, and a thermally protected motor adds safety for long runtimes. The fan ships with a heavy‑duty wall bracket and hardware plus a 6 ft power cord. ETL listing and rugged construction make it suitable as a reliable circulation fan where floor space is limited.
