Today, Air Breeze, the new generation of the world’s best-selling small wind generator, powers countless lights, radios, computers, tools and appliances. It is also used widely to complement solar PV systems. Air Breeze is a perfect choice for hybrid wind/solar systems that provide you with the most reliable year-round energy supply.

Wind energy is clean energy
This isn’t just any energy. Air Breeze produces non-polluting electricity. No fossil fuels are mined or burned to make this electricity. No carbon dioxide is released into the atmosphere. With Air Breeze and the power of the wind, you can forget about carbon footprints.

There is also a marine model available. Please qualify requirements at time of order.

Today we’re releasing our latest and most reliable generation of AIR turbines: the AIR Breeze Marine, for sailing and off-grid coastal applications, the AIR 40, for off-grid remote homes, industry and telecommunication towers in non-corrosive environments, and the AIR 30, for hobby, RV and educational use.

The latest designs required a great deal of efforts on the part of our engineers as well as independent laboratories which helped us pinpoint weak spots in our products. Specifically, the most common causes of failures were excessive heat build-up during extreme wind events and mechanical stresses on the circuit board.

What did we do?

Southwest Windpower is probably the only small wind company with its own wind tunnel. Our engineers gathered information from warranty claims and in-house and external product analysis. We then duplicated identified problems in our wind tunnel and then began the process of changing the design. Specifically we:
1.Performed a comprehensive characterization of the AIR 30 blades to determine the optimal tip and root angle to capture the wind and made changes to the mold.
2. Optimized the software on all AIR products to enhance performance, reliability and reduce excess heat build-up in high wind speeds
3. Upgraded the circuit board using higher temperature rated components to further reduce susceptibility to extreme temperatures
4. Integrated changes to the circuit board configuration to reduce mechanical stress on the board and mitigate component failures

How do we know we did it right?

After completing improvements, we contracted an independent laboratory to perform a Highly Accelerated Life Testing (HALT). HALT uncovers issues in product design, component selection and/or manufacturing that we couldn’t otherwise find without running units in various field environments for an extended period of time. The HALT subjects the turbine to all kinds of stresses and weather and temperature fluctuations in quick succession.

AIR has been around for nearly 15 years and each year we discover new ways the product is used. AIR is found everywhere from a monitoring site in Antarctica to a village clinic in Sri Lanka. It’s the best because it is easy to install and operate. We at Southwest Windpower remain committed to making a difference with wind energy.

The AIR is by far the world’s number one selling small wind turbine.In late 2001 we introduced an entirely new level of technology which previously was only found in today’s state-of-the-art mega-watt-class wind turbines.

The Air X incorporates a new microprocessor-based technology that results in increased performance, improved battery charging capability, greater reliability and the reduction of “flutter” noise from the machine.

The controller allows for peak-power tracking of the wind by optimizing the alternator’s output on all points of the cubic curve and efficiently delivers the energy to the battery. The turbine’s smart controller allows it to actually control blade rotation speed thus eliminating the buzzing noise commonly found with most small wind turbines.

Quieter operation

Previous AIR wind modules relied on their aero-elastic blade design for protection in high winds. This caused a loud flutter noise in winds above 35 mph (16 m/s). Air X’s circuit monitors the wind speed and electronically slows the blades as it reaches its rated output preventing it from going into flutter. This results in a much quieter wind turbine. In high winds, the Air X will continue to produce power at a reduced level until the wind decreases, at which point maximum potential output will resume.

Improved Battery Charging

Previous AIR designs required 300-400 amp hour battery banks so the trickle charge of the wind turbine could be adequately absorbed. The Air X’s charge controller periodically stops charging, reads the battery voltage, compares it to the voltage setting and if the battery is charged, it completely shuts off all current going to the battery. This function is performed within a few milliseconds. The closer the battery is to reaching its full state of charge, the more often the Air X’s circuit repeats this action. This means any size battery bank from 25 to 25,000 amp hours or higher can be charged safely. When the battery has reached its charged state, the Air X will slow to an almost complete stop. Only when the battery has dropped below its voltage set point will it startup and resume charging.

Where and How Air X is Used

The Air X is an ideal product for the person that needs a little power for basic appliances such as TV, radio and a few lights.
Common applications for the Air X

For Medium to High Wind Speeds

The Whisper 100 is designed to operate in a site with medium to high wind speed averages of 12 mph (5.4 m/s) and greater. The 100 provides 100+ kWh per month, 3.4 kWh per day, in a 12 mph average wind. Worried about sound? The Whisper 100 is one of the quietest wind turbines ever tested by the National Renewable Energy Labs. Sound Report.

In addition to its patented smooth acting side furling design, the Whisper 100 has a number of new features that make it ideal for any new or existing photovoltaic system.

A new four bearing spindle for a smoother operation and longer life
An upgraded Yaw shaft that more efficiently delivers current to your batteries
New bronze bushing and larger diameter furling pin for smoother furling action
New castings that allow easy access to the stator for changing voltage Included with every whisper is our new Whisper Controller.
Whisper Controller
Unlike many other small wind systems, the Whisper 100 ships with a controller that includes a diversion load to ensure quiet safe operation of your wind turbine when the batteries are charged.

It installs in minutes and it protects both your wind turbine and battery. The Whisper Controller fits easily inside your battery room. Add the optional LCD display and you will instantly receive real time data on the performance of your Whisper 100.

The display can be mounted on the controller or up to 1000 feet (300 meters) away letting you know what is happening. You can even add an anemometer to your controller and now you can measure wind speed and compare it to the output to make sure you are getting the most from your Whisper 100.

Wind as easy to use as photovoltaics
The Whisper 100 is designed for even the novice. This turbine installs in just a few hours with no welding, no concrete or cranes. Our engineers designed the work out of installing wind turbines.

Solar and wind work together
Solar and wind resources often compliment each other. Generally when it is sunny it is calm and when it is cloudy it is windy. This complimentary effect is even greater during seasonal changes. During the winter and spring when the sun is at its least exposure, the wind is at it highest. A Whisper 100 during these periods is essential to keep your batteries charged and your lights on.

Maximum output in any wind
Exclusive to the Whisper, the side-furling Angle-Governor protects the turbine in high winds by turning the alternator and blades out of the wind, reducing turbine exposure. Unlike other wind turbines that lose as much as 80% of their output when furled, the Angle-Governor allows the Whisper to achieve maximum output in any wind.
