We highlight the features and benefits of the Primus Windpower Air 30 and Air 40 wind turbines to understand the difference between the two popular models.
We have created this blog to help you compare the Primus Windpower Air 30 and Air 40 wind turbines. Overall, they are quite similar; the kWh produced is one of the main differences, which is represented in the model numbers. The Primus Air30 produces about 30kWh per month, while the Primus Air 40 generates about 40kWh. But, beyond that, their differences might not be so clear. In the following paragraphs, we will describe some of the major characteristics of the two models.
It is important to compare the two models because they cost the same, so why would you buy a turbine that produces 30kWh/mo. when you can buy one that produces 40kWh/mo. for the same price?
Former Southwest Windpower started designing the Air wind turbines to meet the demand of commercial remote applications such as oil and gas substations and communication towers. They initially created the Air 30 as an industrial wind turbine designed to withstand the high wind speeds found in those remote and isolated locations. The RPM’s of the Air 30 are high so that it can perform in high wind speeds. The higher RPMs increase the vibrations of the turbine making it louder than her sister turbine the Air 40.
The construction of the Air 30 turbine is the same as the Air X Marine turbine; the materials used to build the marine version are corrosion resistant. Install the Air 30 turbine in remote applications in a non-corrosive or saline environments; the Air 30 is the ideal turbine for areas with high winds where there are no people in the proximity that would be bothered with the sound generated.
Primus Windpower designed the Air 40 for land applications that require a quieter wind turbine.
The outside appearance and size of the Air 40 are the same as the Air 30, they both are gray color; the turbines rated for marine use are coated in white paint. The main difference between the Air 30 and 40 models is that the algorithm of the Air 40 has reduced RPM’s designed to optimize performance in moderate wind speeds. As a result, the Air 40 will operate in a much quieter fashion than the Air 30. Another feature of the Air 40 is that the angle of the blades was modified to reduce vibrations. The Air 40 is the recommended wind turbine for land applications with people in the vicinity. The marine version of the Air 40 turbine is the Air Breeze model which was designed with boats in mind.
In summary, we recommend the Air 30 for remote places with high winds were the vibrations and sounds is not an issue like gas rigs and telecom sites. The Air 40 is the right choice for moderate wind locations where quiet operation is important. Both models come with an integrated charge controller. Order any of the AIR models for 12, 24 or 48 Volt applications. For marine applications or operation in corrosive and saline environments consider the Air X Marine for marine buoys and oil platforms; always use the Air Breeze marine in boats.
