Airmaster 42876 Belt Drive Fan 48 Inches 2 Hp

Product Description

The AIRMASTER 42876 is a high-pressure belt drive fan engineered for demanding industrial and commercial ventilation applications. Built around a 48-inch blade assembly, it delivers 23,556 CFM of airflow powered by a 2 HP motor running on 230/460V three-phase power at single speed. The belt drive configuration allows for flexible motor placement and easier maintenance access compared to direct drive units. This fan is designed for installation by qualified HVAC or industrial ventilation contractors in facilities requiring high-volume air movement across large open spaces.

The AIRMASTER 42876 suits heavy-duty ventilation in warehouses, manufacturing facilities, agricultural buildings, and large commercial spaces. Its three-phase power requirement makes it appropriate for facilities with industrial electrical service. The 48-inch fan diameter delivers high CFM output suited to spaces where large volumes of air must be exhausted or circulated efficiently. This model carries the manufacturer designation HA48MA.

Key Features

• 48-inch blade assembly delivering 23,556 CFM airflow

Compatibility

Designed as an OEM-style replacement or new installation unit for industrial and commercial belt drive ventilation systems requiring a 48-inch fan with three-phase electrical service.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician familiar with three-phase wiring and NEC requirements. Disconnect and lock out all power before mounting or servicing the unit. Verify that the supply voltage matches the selected motor tap — 230V or 460V — before energizing. Ensure the mounting structure is rated to support the fan assembly weight and that belt tension is set per standard drive alignment practices before first run.
