Air blowers are high-volume electric fans designed to push large quantities of air into inflatables — bounce houses, obstacle courses, and large decorative structures — continuously, maintaining internal air pressure rather than sealing it in.
Unlike hand pumps or high-pressure electric pumps that fill and seal an inflatable to a specific PSI, air blowers work differently: they run continuously because large inflatables like bounce castles aren't airtight by design — air escapes through seams and entry points at the same rate the blower replaces it. The result is a structure that stays rigid and inflated only while the blower is running. Motor wattage determines how quickly and how fully the blower can fill a given volume of air space — underpowered blowers leave large structures soft and partially collapsed.
- Air blower motor output typically ranges from 480W for smaller inflatables to 1,100W (1.5HP) for full-size bounce houses.
- Air blowers move air by volume (CFM — cubic feet per minute), not by pressure — making them unsuitable for SUP boards or drop-stitch products requiring 10+ PSI.
- A 1,100W air blower can inflate a standard bounce castle in under 5 minutes at full airflow.
- Air blowers are designed for continuous operation; they must remain running to keep large open-seam inflatables fully inflated.
- Gonflable's 480W blower suits inflatables under approximately 50 cubic feet; the 1,100W model is required for full-size bounce structures.
