Airmaster 24130 Exhaust Wall Fan 18 Inches Two Speed

Product Description

The AIRMASTER 24130 is a low-pressure, all-purpose exhaust wall fan designed for direct-drive ventilation in commercial and industrial settings. Built around an 18-inch blade and a totally enclosed motor, it operates on 115 volts at two selectable speeds, delivering up to 2,504 CFM of airflow. The 1/9 HP motor is housed in a totally enclosed design that resists dust and moisture ingress, making it suitable for demanding environments. Licensed HVAC and mechanical contractors typically specify this unit for wall-mount exhaust applications where reliable, continuous airflow is required without belt-drive maintenance overhead.

The 24130 is suited for light commercial, agricultural, and industrial exhaust installations where wall-penetration mounting is practical. Its two-speed capability allows the installer to balance airflow against noise or energy requirements depending on occupancy or operational conditions. The direct-drive configuration eliminates belt and pulley adjustments, reducing scheduled maintenance. The model designation 18EPR16 corresponds to the 18-inch propeller size and performance class within the AIRMASTER product line.

Installation Notes

Wall exhaust fans of this type are installed by licensed HVAC or mechanical contractors following local mechanical codes and applicable ASHRAE ventilation standards. Disconnect and lock out all electrical power before beginning any wiring or mounting work. Ensure the wall sleeve or louver opening is properly sized for the 18-inch blade sweep and that structural blocking is adequate to support the unit weight of 27 pounds. Confirm single-phase 115-volt circuit capacity and wire gauge are appropriate for the motor draw before energizing.
