For a standard residential bounce house, you need at least a 1,100W / 1.5HP blower — a 480W pump won't move enough air volume to keep a full-size structure inflated under kids actively using it.

The key spec here isn't pressure but CFM (cubic feet per minute) — how much air volume the blower pushes continuously. Bounce houses aren't sealed inflatables; they're constantly losing air through seams and mesh windows, so the blower runs the whole time. A 480W blower is sized for pool floats and smaller inflatables under roughly 50 cubic feet. Anything larger, including a basic 10x10-foot bounce house, needs the 1,100W option to hold its shape under load.

  • Minimum recommended blower for a standard bounce house: 1,100W / 1.5HP motor.
  • 480W blowers suit smaller inflatables under approximately 50 cubic feet of volume.
  • Bounce house blowers are rated for CFM (air volume), not PSI (pressure) — these are not interchangeable with SUP or mat pumps.
  • A correctly matched 1,100W blower inflates a standard bounce castle in under 5 minutes.
  • Blower runs continuously during use — underpowered motors overheat and trip breakers within 15–20 minutes of sustained load.
