How do Bounce Houses Work

Most quality Inflatable Bouncers and Water Parks fall under the category of Continuous Airflow.  This means that an air blower continuously pumps air into the Bounce House or Water Park while the inflatable is in use (If you want to blow it up by mouth, you're in the wrong place!).  Air escapes through the seams and the porous materials.  You will hear air "breathing" out of the inflatable, or even see bubbles in water slides and water parks. This is perfectly normal, and not cause for concern.  Beware of cheap knock offs.  There have been a number of recalls due to low-cost knock offs.  Blowers require power in order to inflate the bouncer, and must be used in areas that have power readily accessible.  If you don't have power for your bouncing party, you will need a generator to run the blower.

Within the continuous airflow category, are two primary types of inflatables: Commercial Grade inflatables and Residential Grade inflatables.
