Mercury Corsair 90-2000 Air Mover – 0.5 HP, 1060 CFM, 3-Speed, 31 lbs

Mercury Corsair 90-2000: 0.5 HP 3-Speed Air Mover for Water Damage and Drying

The Corsair 90-2000 is a 0.5 HP air mover that weighs 31 lbs and produces 1060 CFM airflow at three speed settings. Its roto-molded polyethylene body positions at 0°, 45°, or 90° to direct air under carpet, across hard floors, or up walls depending on the drying application. Up to five units connect in a daisy-chain on a single 15A circuit, making it practical to set up multi-unit drying arrays without running extension cords to each unit individually.

Corsair 90-2000 Motor, Airflow, and Positioning Specifications

• Motor: 0.5 HP (1/2 HP), 115V — draws 2.2A low, 2.4A medium, 2.7A high
• Fan: 9.5" steel blade and frame at 780 RPM
• Airflow: 1060 CFM — sufficient to dry 50–75 square feet of wet carpet or 100–150 square feet of hard floor per unit
• Positioning: 0° (flat), 45°, or 90° — adjusts without tools for under-carpet, floor-level, or wall-directed airflow
• Daisy chain capacity: Up to 5 units on a 15A circuit; up to 7 units on a 20A circuit
• Built-in GFCI outlets: Ground-fault protection at each unit; GFCI tripping at one unit does not affect others in the chain
• Weight: 31 lbs
• Dimensions: 19.2" L x 14.5" W x 19.5" H
• Power cord: 20-foot 16/3-gauge safety cord
• Body: Roto-molded high-density polyethylene — stackable with molded carrying handle
• Safety certification: ETL tested to UL/CSA standards

Where the Corsair Fits in Water Damage Restoration and Drying Programs

The Corsair 90-2000 is sized for water damage restoration contractors, facilities maintenance teams managing post-flooding cleanup, and commercial carpet care operators drying carpet after extraction. At 1060 CFM per unit, a 5-unit daisy-chain on one 15A circuit moves 5300 CFM of air across a floor — equivalent to what a larger, heavier, more expensive drying unit achieves, in five portable 31 lb units that can be positioned independently for directed coverage. The 0°/45°/90° positioning is the primary operating advantage over fixed-angle air movers: water damage restoration frequently requires airflow directed under carpet edges (0° flat against the floor), across open hard floor areas (45°), and up along wet walls (90°) in the same job — the Corsair handles all three without substituting different equipment. For carpet drying after hot-water extraction, positioning at 0° and sliding the unit under the carpet edge creates an air channel between the carpet and pad that dries both simultaneously, which is faster than surface-only drying from above.

Daisy-Chain Wiring, GFCI Safety, and Stacking for Storage

The Corsair's built-in GFCI outlets allow each unit to serve as the power pass-through for the next unit in the chain. Up to 5 units draw a total of 11–13.5A on a 15A circuit at high speed — within the circuit's 80% continuous-load limit of 12A. At 7 units on a 20A circuit (total draw 15.4–18.9A), the circuit operates at its maximum rated load. GFCI protection is local to each unit: if moisture trips the GFCI at one machine, that unit stops but the others in the chain continue operating, which prevents a single floor-level drip from shutting down the entire drying array. The roto-molded polyethylene body stacks securely when the handle is folded flush — units stack flat without tipping, which reduces storage footprint when transporting multiple units in a van or equipment room.
