SWEDFAN offers three main types of starters.
Direct starters, Dahlander starters (for two-speed motors) and Frequency inverters. Depending on the logistics of the tunnelling job SWEDFAN evaluates which type of starter will give the lowest energy cost and recommends which of the three types will be most suitable.

Highly efficient silencers

Our standard silencer are manufactured with mineral wool as absorbing material. For high efficient noise reduction, the silencers are provided with a centre core filled with mineral wool which efficiently also reduces the high frequency sound.
Casting is made from 3 or 4 mm steel, depending on size. Anti-rust protection preformed as for fan casting. Silencers are a safe protection against slinter if a fan should burst.
