Jet fans

Jet fans are used for longitudinal ventilation of tunnels and are normally equipped with silencers.

Jet fans

Jet fans represent a special design of axial fans. The jetfan generates a thrust onto the air of the tunnel and therefore generates a flow on the whole crossection of the tunnel.

available designs

  • thrust from 35 to 2500N
  • size(inner diameter) from 400 to 1800mm
