Choosing the correct blower fan is essential for proper inflation, stability, and long-term reliability. The blower’s amperage determines how much air it pushes into the inflatable — the higher the amperage, the greater the airflow.
📊 Blower Fan Size Chart
| Blower Size (Amps) | Inflatable Height Suited | Fan Hole Size Required |
|---|---|---|
| 0.50A | Up to 80 cm | 6–7 cm |
| 0.60A | Up to 100 cm | 6–7 cm |
| 0.80A | Up to 150 cm | 6–7 cm |
| 0.85A | Up to 180 cm | 6–7 cm |
| 1.0A | Up to 210 cm | 9–11 cm |
| 1.2A | Up to 250 cm | 9–11 cm |
| 1.5A | Up to 300 cm | 9–11 cm |
| Mini 1.2A | Up to 250 cm | 6–7 cm |
🔧 Fan Hole Size Matters
Inflatables are manufactured with specific fan-hole diameters, so blower size is not just about power.
- 6–7 cm holes → 0.50A to 0.85A blowers
- 9–11 cm holes → 1.0A, 1.2A, 1.5A blowers
- Mini 1.2A → High-power option for inflatables with smaller 6–7 cm holes
⚠️ A blower that is too large will not fit, and one that is too small will not inflate the item correctly.
💨 How Blower Amperage Works
- Higher amperage = more airflow
- More airflow = firmer inflation, better shape, and improved performance
- Larger, taller, or wider inflatables need more air volume, not just height coverage
⭐ AirFigs Pro Tip
If your inflatable is:
- Near the top of a size range
- Has LED lights
- Has moving parts or wide sections
👉 Choosing the next size up (where hole size allows) will improve performance and reduce strain on the blower.
🛠 How to Check What You Need
- Open the zip at the base of your inflatable
- Measure the fan hole diameter
- Check the inflatable height
- Match both to the chart above
