The Primus AIR Silent X wind turbine is a new addition to the Primus family. The AIR Silent X is a combination of the high end Silent Wind carbon fiber blades with the renowned Air Breeze wind turbine body. The addition of the carbon fiber blades reduces the noise output of the turbine while also increasing the power output.
The body of the turbine weighs only 13 pounds. It is painted with a corrosion resistant finish over cast aluminum, which allows for longevity even in marine/coastal environments.The AIR Silent X energy output reaches 90 amp-hr. per day at an average of 12 mph. It includes a built in microprocessor-based tower up charge controller in the body of the wind turbine with factory settings that is compatible with most applications, and can be adjusted easily if needed.
The startup wind speed of the AIR Silent X is 7 mph, and will automatically shut off with a wind protection speed of 110 mph. The AIR Silent X wind turbine operates at 12VDC only and integrates very easily with 12VDC PV systems.
The stop switch is included with all Silent X wind turbines.
All Primus AIR Silent X models include a green LED light visible at the bottom of the turbine's body. The LED light will be solid when the turbine is producing energy. A slow flashing means the turbine is in regulation mode, which is when the turbine spins slowly but no energy is being produced. A fast flashing means the winds are strong and the turbine has entered overspeed protection.
Some of the AIR Silent X features:
- Improved reliability backed by a 5 year limited warranty

About Primus Windpower
Primus Wind Power is located just outside of Denver, Colorado and has been a leading producer of wind turbines in the United States since the 1990's. They recently acquired the AIR turbine from Southwest WindPower (in 2013). Primus manufactures their products here in the U.S. and ships directly from their Colorado location. They are committed to satisfying off-grid, marine and residential customers with high-end wind turbines for many different applications. They have engineered five different turbine models to better suit their clienteles needs for specific projects.
The Primus turbines weigh less than 20 pounds but they are extremely durable, reliable and efficient. In addition to their turbines, they also design and manufacture their own blades and control devices such as the Wind Control Panel. They offer their most common replacement parts and accessories to the public including blade replacement kits, replacement nose cones, pole and stays mounts for marine purposes, hardware kits, stop/start switches, and control panels for improved monitoring.
All Primus wind turbines have built in charge controllers with external LED light indicators, which make them very easy to operate and monitor. The turbines also have automatic emergency shutdown modes that protect them from extremely high wind speeds. Primus turbines can be connected directly to a battery bank for power and work extremely well in conjunction with solar panels.
In their literature (website) Primus offers several detailed graphs showing peak wind and solar resources in certain regions throughout the U.S., and whether these regions benefit more from solar, wind, or a combination of the two. Primus Wind Power offers a 5-year warranty on all their wind turbines, as well as accessible technical support staff for any issues that may arise while installing or maintaining your wind turbine.
Choosing a Primus wind turbine
Primus Wind Power manufactures five lines of wind turbines. All five are exclusively for battery charging with a rated power of 400W and are available in 12V, 24V, and 48V. The five turbine models are very similar in appearance but were designed with different applications in mind. Here is a quick summary to help you choose the right turbine for your application.
The Air 30 is assembled with high wind blades and a high RPM charging algorithm. They are designed for remote high wind locations where access can be challenging, for example telecom towers or remote oil facilities. The Air 30 is made for land use only, for remote marine applications use the Air X Marine.
The Air 40 is built in the same body as the Air 30 turbine, however the blades and the RPMs are optimized for a quiet operation. The Air 40 is a great wind turbine for land applications such remote cabins where people are in the vicinity.
In short, the Air Breeze is the marine version of the Air 40 turbine. The cast aluminum body is painted with aircraft quality paint and is assembled with a marine grade O-ring seal and stainless steel fasteners. For boats and sailboats this is the right turbine to use, unless you want a quieter turbine, the Air Silent X.
Air Silent X
The Air Silent X turbine displays the same marine protection as the Air Breeze but comes equipped with blue carbon fiber blades for low sound emission.
Air X Marine
As mentioned above the Air X Marine is the marine version of the Air 30 turbine. Without question it is the right turbine for remote marine applications such as buoys and navigation lights.
