One horsepower of motor sits behind this 750-watt blower, spinning at 3330 rpm and moving air at 26 meters per second, which suits the larger water slides and multi-bay bouncers that a smaller unit struggles to hold up. The 4.5-inch vent matches the collar on most garden inflatables. An IPX4 rating and a sealed cover over the power switch mean a light shower does not end the party, and the plug carries a ground fault interrupter for outdoor circuits. The cable measures 25 feet on 120 volts at 60 hertz, so the blower sits well clear of the play area. Wind pressure reaches 1.90 kilopascals. Housing dimensions are 15 by 10 by 15 inches at 13.5 pounds, light enough to carry in one hand and small enough to store on a shelf.
