Airmaster 24120 Exhaust Wall Fan 16 Inches Two Speed

Product Description

The AIRMASTER 24120 is a direct-drive, low-pressure exhaust wall fan designed for general ventilation in commercial and industrial applications. Built around the 16EPR16 model configuration, it moves 1,881 CFM at low pressure using a totally enclosed motor rated at 1/9 HP and 115 volts. The two-speed operation lets technicians match airflow to the demand of the space without additional controls. At 16 inches, the fan is sized for standard wall penetrations and is installed by HVAC or general mechanical contractors as part of an exhaust ventilation system.

This fan is suited for light commercial, industrial, or agricultural environments where a compact, wall-mounted exhaust solution is required. The totally enclosed motor makes it appropriate for dusty or debris-prone spaces where an open motor would be at risk. Two-speed capability supports energy management in spaces with variable occupancy or load. Typical installations include equipment rooms, warehouses, garages, barns, and utility spaces that require reliable, continuous or intermittent exhaust ventilation.

Installation Notes

Installation should be performed by a licensed HVAC or mechanical contractor in accordance with local mechanical codes and ASHRAE ventilation standards.
