The world’s best selling marine wind turbine is by far the Air-X Marine. This small wind generating turbine was designed for sailboats and other boats too. The marine grade wind turbine was designed for boats with all the weather elements in mind with its powder coating and stainless steel fittings for corrosion protection in a marine environment. The Air-X Marine is simple to install and all that is necessary for mounting is a 1.5” schedule 40 pipe (1.9” OD, 48 mm) which is not included.

The Air X Marine Wind Turbine has a start-up wind speed of only 6 Knots (7 mph, 2.7 m/s) and at wind speeds of 28 mph thas a start-up wind speed of merely 6 knots (7 mph, 2.7 m/s) and at wind speeds of 28 mph the Air-X Marine produces 400 Watts of power, the powering possibilities are endless. With blue water cruisers purchasing over 70,000 turbines worldwide in just a few short years, the AIR X Marine has become the standard wind turbine. Power supplied from the AIR-X Marine is great for the refrigerator, auto-pilot, water maker, lights, navigational equipment, and communication equipment. The AIR-X Marine features patented peak power tracking for maximum power no matter how high the wind speeds. Other users have operated all of the equipment aboard their 40 ft (12 m) sailboat including (with an inverter) a microwave, coffee pot, bread maker, TV, VCR, toaster, as well as 12 volt system radio, radar, lights, loran, and refrigerator. The AIR-X Marine was their only source of recharging apart from occasional engine motoring.

Previously Air wind modules relied on for protection their aero-elastic blade design extreme winds, causing a disturbing flutter noise in winds above 35 mph (16 m/s). The Air-X Marines blades are made of carbon fiber composite plus there is a new microprocessor-based speed control which results in increased performance, increased battery charging capability and reduces the “flutter” noise commonly found with most small wind turbines. To eliminate the buzzing noise the turbine’s smart controller allows it to control the rotation speed .The controller enables for peak-power tracking of the wind by optimizing the alternator’s output on all points of the cubic curve and then efficiently supplies the energy to the battery. The added increased power production comes from the new series carbon-reinforced blades with a modified pitch angle. The new electronics are considered a great improvement over the AIR 403 controller that consists of diode-rectification and a simple on/off voltage switch.

A much lower stress design has been engineered. The new AIR-X limits power on the input side of the electronics by controlling the torque from the blades. The power no longer has to be dissipated by the electronics resulting in lower stress on the circuit, bearings and other materials. Mostly in high wind speeds is when stress on a wind turbine happens. Throughout these circumstances, the electronic stall design decreases the blade speed to 600 rpm, thus drastically reducing turbine and tower loading while still creating energy. The advantage is the greater confidence in turbine operation in high wind conditions without having to manually operate the stop switch. Air-X Marine has outstanding resistance to the effects of the sun, wind, and water by vastly improving body preparation and the treatments of the marine paint during construction ensuring a more durable powder-coat protection to the body and internal components. Even when subjected to the most intense sun, wind, and water situations the Air-X Marine surpasses the others.

The Air-X Marine also has  increased the trickle charge of the wind turbine so it can be effectively absorbed, preceding AIR designs called for 300-400 amp-hour battery banks. The AIR-X’s charge controller periodically interrupts charging and reads the battery voltage then compares it to the voltage setting to see if the battery is charged then it completely shuts off the entire current going to the battery. This action is completed within a few milliseconds. The closer the battery is to achieving its full state of charge, the more frequently the AIR-X’s circuit replicates this action. What this ultimately means is any size battery bank from 25 to 25,000 amp-hours or higher can be charged safely. When the battery has reached its fully charged state, the AIR-X will come to almost a complete stop. Only when the battery has dropped below its voltage set point will it startup again and restart charging. This creates a huge benefit by lengthening the battery life and not overcharging it.
