The GENESIS G20BOX-BLK is a 20-inch blade box fan rated at 2,330 CFM maximum airflow, drawing 0.50 amps at 120 volts and consuming 53 watts. It delivers three selectable speeds through a flat-mount design suited to floor, window ledge, or surface placement. The unit weighs 8 pounds and measures 20 inches high by 20 inches wide by 4 inches deep, making it compact enough for tight spaces. HVAC service technicians, facilities maintenance staff, and ventilation contractors install this type of fan for spot cooling, air circulation, and temporary ventilation during service calls or permanent supplemental airflow applications.
The G20BOX-BLK is suited for residential and light commercial environments where portable, high-volume air movement is needed. Typical deployment includes equipment rooms, server closets, workshops, garages, and job sites requiring temporary or supplemental ventilation. The flat-mount housing allows it to sit flush on a surface or fit into a standard window opening. Three speed settings let the installer match airflow output to the specific requirements of the space without additional controls or wiring.
Designed as a portable box fan for standard 120-volt residential and light commercial electrical circuits, suitable for floor, shelf, or window-ledge placement in spaces requiring supplemental air circulation.
Installation of this fan is typically performed by facilities maintenance personnel or HVAC technicians as part of a ventilation or temporary cooling setup. Verify that the circuit supplying the fan is rated for 120 volts and that the outlet is properly grounded per NEC requirements. Do not block the fan intake or discharge grille, as restricted airflow can cause overheating. Confirm the mounting surface is level and stable before placing the unit in service.
