The diameter of the spigots in the Stream 100/125 model can be changed using adapters, and in the Stream 150/160 model
using the rubber seal.
On outlet (discharge) spigot side it is necessary to install:
• in case of horizontal installation – a duct with a length of at least 1 m;
• in case of vertical installation – a canopy preventing moisture from getting into the fan.
The outlet spigot must always be connected to the air duct.
