Primus AIR 30


Primus 1-AR30-10, AIR 30 wind turbine, 440 Watt, internal regulator

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 30 produces best at medium to high wind speeds and can work in a marine (salt spray) environment. For a low-wind environment the AIR 40 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 30 provides energy quietly and efficiently. The AIR These are the official type codes:

Primus 1-AR30-10-12: 12 Volt AIR 30
Primus 1-AR30-10-24: 24 Volt AIR 30
Primus 1-AR30-10-48: 48 Volt AIR 30

Turbine Selection Matrix

Low to Moderate Wind Speeds High Wind Speeds Very High Wind Speeds
under 5.5 m/s (12 mph) average December wind speeds 5.5 – 7 m/s (12 – 15 mph) average December wind speeds Over 7 m/s (15 mph) average December wind speeds
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.
