Free up your floor space with this 2-pack of 20-inch wall mount fans, each delivering up to 4000 Cfm of high velocity airflow for warehouses, workshops, and garages. Mount them on walls or ceiling beams to keep air circulating overhead while leaving the ground clear for equipment and foot traffic. All-metal construction with aluminum blades handles the demands of commercial and industrial environments, and three speed settings let you dial in the right amount of airflow for the conditions. Manual angle adjustment directs the breeze where cooling matters most, and noise stays at a comfortable 60 dB or below even on high speed. Each fan includes complete mounting hardware for straightforward installation on any solid wall surface.
