A portable inflatable spa loses much of its appeal when weak bubbles, inconsistent airflow, or a failed blower leaves you with an ordinary tub. These replacement air blowers restore the air supply for compatible spa systems, with models ranging from 1.0 HP for compact setups to 2.0 HP for larger jet arrangements. Your existing model number, electrical voltage, horsepower, and pipe connection determine the right replacement.
The Lineup, Simplified
6320241 Spa Blower 240V 2HP
6320141 Spa Blower 120V 2HP
6310241 Spa Blower 240V 1HP
6316220F Spa Blower 240V 1.5HP
6315141 Spa Blower 120V 1.5HP
6310131 Spa Blower 120V 1HP
A Breakdown Of The Leading Choices
A 240-volt spa with more than 14 jets needs an air supply with enough capacity to keep the water moving consistently. This 2.0 HP model, meaning a 2-horsepower motor rating, is designed as a replacement for the 6320241 blower and connects through 2-inch plumbing. That combination makes it the most substantial option in this lineup for larger residential or commercial hydrotherapy systems.
For everyday owners, the internal cushioning rubber is a thoughtful detail because it helps reduce motor vibration and the associated humming around the tub. The spring check valve also avoids the foam-based plate design that can age and impede airflow, although matching the old blower remains essential.
Real Benefits
- The 2.0 HP rating supports jet arrangements containing approximately 14 or more outlets.
- Internal rubber cushioning helps soften vibration and background noise.
- A spring check valve supports smooth airflow without relying on aging foam components.
- The 2-inch connection suits many existing spa air-delivery lines.
- Installation is listed as taking about five minutes with compatible equipment.
Trade Offs
- The 240-volt configuration requires a matching electrical supply and compatible wiring setup.
- Model 6320241, horsepower, voltage, and pipe size must all match the blower being replaced.
Key Specs
Built With In Mind
This blower suits owners of a larger 240V spa whose existing unit carries model 6320241 and uses 2-inch air plumbing.
Where A Sibling Pick Shines
The 6320141 Spa Blower 120V 2HP serves owners of a large 120V system more directly.
The same 2.0 HP output offered by the 6320241 model comes here in a 120-volt configuration. That difference matters for a large spa already connected to a 120V supply, particularly one with approximately 14 or more jets. This is the 6320141 replacement, so the model number must correspond with the unit installed in your tub.
For a busy home spa, the combination of steady airflow and vibration-dampening rubber can make the installation feel less intrusive. You still get the spring-valve design intended to maintain airflow, plus a 2-inch plumbing connection and a stated five-minute installation window for compatible systems.
Strengths Worth Knowing
- Delivers 2.0 HP airflow for approximately 14 or more jets.
- The 120V configuration fits qualifying residential and commercial installations.
- Rubber cushioning reduces vibration transferred through the motor housing.
- The spring check valve avoids a foam plate that can deteriorate with age.
Worth Noting
- Its 2-inch connection and model 6320141 must align with the existing spa equipment.
Made For
This model makes sense for owners of a large 120V hydrotherapy system with a matching 6320141 blower and 2-inch plumbing.
Consider Something Else When
The 6315141 Spa Blower 120V 1.5HP is the closer fit for a system with eight to twelve jets.
A smaller spa does not need the airflow capacity associated with a 14-plus-jet layout. This 1.0 HP blower is listed for approximately four to eight jets and replaces model 6310241 in a 240V installation. That gives you a more proportionate choice than the 6320241 Spa Blower 240V 2HP, especially in a compact residential setup.
Across an evening of use, the internal cushioning helps limit the motor’s vibration, while the spring check valve keeps the air path designed around a non-foam mechanism. The 2-inch connection makes it usable with many standard spa systems, though the listed five-minute installation depends on compatible plumbing and electrical arrangements.
A Few Highlights
- Provides a 1.0 HP option for roughly four to eight water jets.
- Cushioned internals help reduce the vibration that accompanies a running blower.
- Uses 2-inch plumbing, a common connection across the listed models.
Practical Considerations
- Its 240V supply must match the wiring and electrical setup of the spa.
- The four-to-eight-jet range makes it less suitable for larger jet arrangements.
- Model 6310241 must match the blower being replaced.
Quick Facts
Right Fit For
This blower suits owners of a compact 240V spa with four to eight jets and model 6310241 equipment.
A Better Fit Elsewhere
The 6316220F Spa Blower 240V 1.5HP accommodates systems with eight to twelve jets.
The middle ground in this lineup arrives as a 1.5 HP blower for 240V systems with approximately eight to twelve jets. Model 6316220F fits between the four-to-eight-jet capacity of the 6310241 and the larger 14-plus range of the 6320241. For a residential spa with a moderate number of outlets, that balance can be more practical than choosing the highest available horsepower.
The quiet-running design centers on rubber vibration cushioning rather than a claim about a particular sound level. Its spring check valve supports consistent airflow without the aging foam plate used in some older assemblies, and the 2-inch fitting works with the plumbing arrangement described for the system.
Where It Excels
- The 1.5 HP rating fits jet layouts of approximately eight to twelve outlets.
- Rubber cushioning helps soften vibration during operation.
- A spring check valve supports airflow without a foam plate.
- Installation is listed at about five minutes for compatible systems.
Minor Gripes
- The 240V requirement narrows compatibility with 120V installations.
- Owners must verify model 6316220F and the 2-inch pipe connection before fitting it.
Feature Card
Who Will Love This
This model fits owners of a 240V spa with eight to twelve jets who want more capacity than a 1HP blower.
Another Choice May Suit
The 6315141 Spa Blower 120V 1.5HP serves a comparable jet range on a 120V supply.
Here is the same 1.5 HP capacity as the 6316220F, adapted to a 120V supply. The 6315141 model is intended for systems with approximately eight to twelve jets, making it a practical choice for a standard residential spa where a 120V electrical arrangement is already in place. You gain useful airflow capacity without moving to the 2HP models.
The internal rubber helps reduce vibration and its associated noise, useful when the spa sits near living spaces. A spring check valve keeps the air mechanism separate from aging foam components, and the stated five-minute setup refers to an already compatible 2-inch plumbing arrangement.
Well-Handled Touches
- The 1.5 HP motor rating supports approximately eight to twelve jets.
- Cushioning and the spring valve address vibration and airflow resistance.
Details To Watch
- A 120V supply does not match a 240V spa installation.
- The listed jet range may be modest for a heavily equipped spa.
- Both model 6315141 and the 2-inch connection must match the system.
The Right Fit

Product Snapshot
Best Suited To
This model suits owners of a small 120V spa with four to eight jets and a matching 6310131 blower.
Reach For A Different Pick When
The 6316220F Spa Blower 240V 1.5HP better serves a mid-size 240V system with eight to twelve jets.
Match The Blower Before Ordering
Confirm The Electrical Supply
Voltage is the first distinction because these replacements come in 120V and 240V versions. A 120V blower belongs with a compatible 120V supply, while the 240V models require the corresponding electrical arrangement. Treat the old blower label as the starting point rather than selecting by horsepower alone.
Identify The Model And Connection
Each number identifies a specific replacement: 6320241, 6320141, 6310241, 6316220F, 6315141, or 6310131. All six use 2-inch plumbing in the listed configurations, so confirm that the connection and clearance around the installation area match your existing arrangement.
Use The Jet Count As A Guide
The listed capacity progresses in clear bands: approximately 4 to 8 jets for the 1HP models, 8 to 12 for the 1.5HP models, and 14 or more for the 2HP models. Jet count provides a useful capacity check, though the original manufacturer’s matching requirements remain the deciding factor.
Account For Noise And Installation
Internal rubber cushioning helps reduce vibration and the hum associated with a running blower. The spring check valve also replaces the aging foam plate approach found in some older equipment. Installation is listed at about five minutes for compatible systems, so plumbing access, electrical requirements, and the available equipment area deserve a check beforehand.
Common Mistakes In Spa Blower Replacements
Mistakes Worth Dodging
Choosing by horsepower alone can lead to an electrical mismatch, while choosing by voltage alone can leave you with the wrong model or pipe size. Record the model number, voltage, horsepower, and connection from the installed blower before selecting a replacement. Confirming the jet count adds another useful layer of capacity guidance.
What Separates Higher Output From Basic
The 2HP models provide more listed airflow capacity for jet arrangements with approximately 14 or more outlets than the 1HP alternatives. That added motor output makes sense for larger systems, while smaller spas gain little from exceeding their listed jet range. The 1.5HP options occupy the practical middle ground.
Frequently Asked Questions For Blow Up Spa
How do I know which spa blower matches?
Match the replacement to the model number, horsepower, voltage, and 2-inch pipe connection shown on your installed unit. The jet count provides a further capacity check.
Can a 120V blower replace a 240V blower?
No. A 120V blower should not replace a 240V unit because the electrical supply and model requirements must match. Choose the version corresponding to the existing system.
How many jets can a 1HP blower support?
The 1HP models are listed for approximately four to eight jets. The 1.5HP models cover approximately eight to twelve jets, while the 2HP models support roughly 14 or more.
What does the spring check valve do?
A spring check valve regulates airflow within the blower without relying on an aging foam plate. This design is intended to keep the air path operating as the motor runs.
Do all six blowers use 2-inch plumbing?
Yes. Every listed model is designed for a 2-inch pipe connection, though the model number, voltage, horsepower, and jet capacity still need to match the spa.
Final Verdict
The right replacement comes down to an exact match rather than the largest motor available. Choose the model that preserves your voltage, pipe size, and listed jet capacity, from the compact 1HP units to the 2HP options for larger systems. A careful model-number check can prevent an avoidable return and keep your spa operating as intended.
