Swapping a blower is mostly about compatibility and safe setup.

• Match the type: Yard décor often uses 12V replacement fan motors (around 0.5A–1.5A, sometimes with LED strings). Bounce houses and slides use 110V blowers rated in watts/HP.
• Check size/power: Confirm the inflatable’s air tube fit and match the blower’s watt/HP rating to the maker’s guidance.
• Swap carefully: Unplug power, remove the old unit, seat the new blower or motor, secure straps/zip ties, and ensure no kinks or gaps.
• Test and inspect: Inflate, listen for leaks, and verify steady pressure.

Use outdoor‑rated cords with GFCI protection. If specs aren’t clear, your inflatable’s manual is a helpful reference.

Size depends on the inflatable’s volume and design.

• Holiday yard inflatables (about 3–12 ft): Compatible 12V replacement fan motors (roughly 0.5A–1.5A).
• Small bounce houses/compact structures: Around 380–450W (about 0.5–0.6 HP).
• Mid‑size bouncers and slides: Roughly 680–750W (about 1.0 HP).
• Larger/taller slides or structures: About 750–950W (around 1.3 HP) or higher; some go up to 2 HP.

Also review airflow/pressure details (e.g., RPM or Pa) if listed, and follow the inflatable manufacturer’s recommendation. When uncertain, matching the original blower’s rating is a practical starting point.

Power draw varies by model and application.

• Decor replacement fans: Many run on 12V and draw about 0.5–1.5A.
• AC bounce house blowers: Common ratings include 250W, 350W, 380–480W (about 0.5–0.6 HP), 680–750W (about 1.0 HP), and 750–950W (about 1.3 HP). Heavy‑duty options can reach 2 HP.

Higher wattage generally means higher electricity use. The listed wattage is a helpful guide, though actual draw can vary with setup and conditions. For outdoor use, plug into a GFCI‑protected outlet and use an outdoor‑rated extension cord sized for the blower’s load.

For inflatables, a purpose‑built blower is typically a safer choice than DIY.

• Safety features: Retail blowers often include outdoor‑rated housings, grounded plugs, and certifications (e.g., UL/ETL) that DIY builds may lack.
• Right fit: You’ll find 12V replacement motors for yard décor (some with LEDs) and higher‑watt/HP blowers for bounce houses, making it easier to match tube size and power.
• Designed for continuous use: Built to handle steady airflow and typical weather exposure.

Compare specs on the product page with your inflatable’s manual to confirm compatibility. For custom setups or long cord runs, a qualified electrician can offer guidance.

Horsepower reflects the blower’s potential airflow and pressure, which affects inflatable size support.

• 0.5–0.6 HP (around 380–450W): Often used for smaller bounce houses or compact inflatables.
• 1.0 HP (about 680–750W): Typically suited to mid‑size bouncers and slides.
• 1.3 HP and higher (around 750–950W+): For larger or taller structures; some units go up to 2 HP.

Beyond HP, check other specs such as RPM (e.g., ~3300–3400) and pressure ratings (if listed). Aligning the blower with the inflatable maker’s recommendation often provides more consistent performance.
