Choosing the Correct Ultra 9000 Blower
When replacing an existing spa air blower, first check the label on your current blower. In most replacement applications, you should match the horsepower and voltage of the existing unit.
Before ordering, confirm:
- Horsepower: 1 HP, 1.5 HP or 2 HP
- Voltage: 120V or 240V
- Plumbing connection: 2" slip fitting
- Electrical connection: Verify the plug/cord configuration on your existing equipment
- Available installation space and blower orientation
Replacing an Existing Spa Air Blower?
The Ultra 9000 is designed for replacement and OEM spa applications and is available in six horsepower/voltage combinations. Matching the specifications printed on your existing blower is generally the best starting point when selecting a replacement.
Important: Do not select a higher-horsepower blower simply because it is more powerful. Spa air systems are designed around specific airflow and pressure requirements. When replacing an existing blower, match the original horsepower and voltage unless your spa manufacturer specifies otherwise.
If you're unsure which Ultra 9000 model you need, contact us with the manufacturer, model number, horsepower and voltage shown on your existing blower and we'll help identify the correct replacement.
