Primus 1-ARSM-15, AIR Silent X wind turbine for marine environments, 440 Watt, silent carbon-fibre blades, internal regulator, marine grade
Primus AIR Silent X
$1,820.02 – $1,830.72
The Primus AIR-series of small wind turbines has been around since 1995, with over 150,000 installed since! Theirs is a proven product, for a reasonable price.
The AIR Silent X is made with hand-laminated carbon-fibre blue blades, designed to be quiet, even at high wind speeds. This makes the AIR Silent X particularly suitable for use on a boat etc.
The AIR Silent-X produces best at medium to high wind speeds and can work in a marine (salt spray) environment. For a low-wind environment the AIR Breeze could be a better choice. Peak-power output is 440 Watt, and there are versions for 12/24/48 Volt battery-charging applications in coastal, desert or Arctic environments. It delivers the energy you need for communications, offshore structures, sailing or remote monitoring, to name a few. A small wind turbine can also be a great addition to an off-grid system, to provide energy during those dark (but windy) winter days. With a build-in charge controller, the AIR Silent-X provides energy quietly and efficiently. The AIR Silent X is corrosion resistant, covered in aircraft quality paint with a marine grade O-ring seal and stainless steel fasteners, ensuring durability in challenging conditions. These are the official type codes:
Primus 1-ARSM-15-12: 12 Volt AIR Silent X
Primus 1-ARSM-15-24: 24 Volt AIR Silent X
Primus 1-ARSM-15-48: 48 Volt AIR Silent X
The AIR Silent X includes a stop-switch.
Be sure to check out the Primus Webinars to learn more about installation, wind resources, turbine placement etc.
Please note that the Primus turbines start to protect themselves from overheating above wind speeds of around 35 mph (16 m/s). This means it shuts down for 2-1/2 minutes, then runs again for a some of time, and shuts down again, this repeats. The effect is much lower energy production for these very high (and unusual) wind speeds. This is normal, and necessary for the turbine’s survival.

|Coastal Use||AIR Breeze||AIR X Marine, AIR Silent X||AIR X Marine, AIR Silent X, with TriStar 45 and TL-100 diversion load|
|Inland Use||AIR 40||AIR 30||AIR 30 with TriStar 45 and TL-100 diversion load|
The marine-type turbines (AIR Breeze, AIR X Marine, and AIR Silent X) can of course also be used at inland sites. They are just a more corrosion-resistant version of the inland wind turbines.
