Sandia Gen-Air 90-0000 Commercial Air Mover – 2,400 CFM, 3-Speed, 1/2 HP, Stackable

Sandia Gen-Air 90-0000 3-Speed Commercial Air Mover for Water Damage Restoration

The Gen-Air runs a 1/2 HP motor through a 10-inch steel fan blade in three speeds — 780 RPM (1,500 CFM), 1,000 RPM (1,900 CFM), and 1,150 RPM (2,400 CFM) — inside a 14-inch roto-molded high-density polypropylene chassis. Safety screens front and back protect the fan blade and operator. The unit stacks for compact storage and transport between water damage restoration jobs, and angles to direct airflow at floors, walls, or ceilings without adapters.

Air Mover Deployment in Water Damage Restoration

Water damage restoration protocols (IICRC S500) specify airflow equipment placement to create evaporative drying conditions across affected materials. Air movers positioned at low angles along walls and under furniture create a boundary layer airflow pattern that accelerates moisture evaporation from wet carpet, subfloor, and structural materials. The Gen-Air's 3-speed selector allows adjustments as moisture levels change during the drying period — high CFM initially when moisture load is heaviest, lower speeds as materials approach target moisture content to reduce over-drying risk. Xactimate code for air mover placement in water damage restoration billing is DRAIR, and equipment days are logged per unit per 24-hour period.

Stacking and Daisy-Chain Considerations

The Gen-Air's stackable design allows multiple units to be transported in a single load and stored vertically when not in use, which matters for restoration contractors running multiple concurrent jobs. The 20-foot cord provides adequate reach in most residential and commercial room configurations. For jobs requiring many units across a large floor plan, the cord length and outlet density at the job site determine how many units can be deployed without extension cords — the preferred configuration is direct plug-in to avoid voltage drop that reduces fan motor speed at high CFM settings.
