We distinguish between two different types of snow gun: Fan guns and snow lances. The snow generation principle is the same for both types of device, the difference lies in the amount of snow produced, the cost and the application range. Selecting the most suitable snow gun depends on the hillside orientation, temperature, slope width, amount of snow required, gradient of the terrain, wind situation and air circulation. The mountain’s individual characteristics must be taken into account. Both fan guns and snow lances are available as manually adjustable or fully automated models. Both types can produce a range of different snow qualities (from completely dry to wet).
