The X-400A is an affordable and durable air mover which includes a daisy chain feature. What is daisy chain? Daisy chaining is often used in the restoration industry meaning that multiple units can be connected to each other without the use of an extension cord. Each unit has an on board power outlet which allows up to three extra machines, with the combined power of 15 AMPS, to be plugged into it. The X-400A creates up to 1600 CFM of airflow while still being super lightweight (17 lbs.) and compact. It is also made from ABS plastics, which is the same material used in NFL helmets. This air mover is great for anyone with a business where many outlets are necessary. • X-400A : 1/4 HP, 1600 CFM, 3 Speeds Air Mover With Daisy Chain (ABS) • 1/4 HP, 3 Amps, 1600 CFM • Daisy Chain, 3 Speeds, Cord Length 20" • 4 Positions, Stackable • ETL/CETL Safety Certified
