Costzon 1.25HP Air Blower for Bounce Houses — 950W Inflatable Pump Fan, Quiet Portable with 4-1/4" Outlet

Costzon Air Blower is a 1.25HP (950W) commercial-grade pump fan designed to rapidly inflate bounce houses, water slides and other large inflatables while running quietly and safely.

Built for backyard parties, rental businesses and event setups, this compact electric blower combines a high-efficiency motor with noise-reducing impellers and safety features so you can inflate large inflatables quickly without a bulky machine. The unit’s 4-1/4" outlet fits most standard inflatable collars, and thoughtful touches — like a covered switch, dual vent guards and a convenient top handle — make it practical for repeated use at events and transport between locations.

How fast and powerful is this blower for filling a bounce house?

The Costzon blower pairs 1.25 horsepower with a 950-watt motor to deliver rapid airflow so inflatables reach operating pressure quickly. Its measured inflation rate supports high-volume air movement appropriate for large residential and commercial inflatables.

• Inflation rate: up to approximately 45,200 CFM (968.8 m³/min) at rated conditions
• Air outlet: 4-1/4" (outside diameter) compatible with common collars

Is the blower safe and simple to operate at events or rentals?

Yes — the unit includes built-in safety and ergonomic features for repeated use. A clear protective cover over the power switch and wire mesh guards over both vents reduce the chance of water or accidental contact, while the anti-slip body and top carry handle make moving and powering the blower straightforward.

• Covered switch to help protect against moisture
• Dual wire-mesh vent guards to prevent hand contact with moving parts
• 13-foot power cord and ergonomic grip for convenient setup and placement

Will the blower be too loud for backyard parties or commercial use?

The Costzon blower was engineered with high-quality impellers and a built-in bearing to reduce vibration and noise compared with basic models. While no powerful blower is silent, this design moderates sound so it is less intrusive during inflatable operation and quicker to manage at events.

• Noise-reducing impellers for lower operational sound
• Durable built-in bearing for smoother motor rotation and less vibration
• Lightweight impeller material keeps performance high without extra mass

How portable and adaptable is this blower for different inflatables?

The blower’s compact footprint and integrated handle make it easy for one person to carry and place. Its standard outlet size, rated voltage and robust airflow make it suitable for bounce houses, water slides, obstacle courses, air sofas and many other inflatables.

• Compact dimensions and top handle for single-person transport
• 110–120V AC / 60Hz, 8.7A power input for common household or event outlets
• Broad compatibility with many inflatable types and event setups
