Airmaster 23002 Low Pressure Shutter Fan 12 Inches

Product Description

The AIRMASTER 23002 is a 12-inch low pressure shutter fan designed for direct-drive ventilation applications in commercial and industrial settings. Running on 115/230V single-phase power at 1/30 HP, it delivers 815 CFM of airflow through a shutter-style housing that opens on operation and closes when the unit is off. The totally enclosed motor resists dust and moisture ingress, making it suitable for demanding environments. Licensed electricians and HVAC technicians are the typical installers for this class of exhaust and supply ventilation equipment.

This fan is well suited for wall or ceiling exhaust applications in warehouses, utility rooms, equipment enclosures, and light industrial spaces where low-pressure ventilation is required. The direct-drive design eliminates belt and pulley maintenance, reducing long-term service requirements. The shutter mechanism provides passive damping when the unit is not running, limiting backdraft and environmental infiltration. The EPRSM12 model designation identifies the specific fan assembly within the AIRMASTER product line.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with NEC requirements for motor-driven ventilation equipment. Disconnect and lock out all power before wiring or servicing the unit. Verify the supply voltage matches the motor nameplate rating before energizing. Ensure the shutter swings freely and the fan housing is sealed to the mounting surface to prevent air bypass.
