Jalousie Dampers

Our popular jalousie dampers are designed for round ventilation ducts but can easily be adapted for square or rectangular connections upon request.

These are specially designed for lumber kilns and are primarily made of stainless steel. The gaskets are made of Viton, which we have used successfully for many years and which performs well inside lumber kilns.

We stock jalousie dampers for round ducts in the following dimensions: 630, 800, 900, and 1000 mm.
We have also designed dampers for round connections in 400, 500, 710, 1120, and 1250 mm.

We typically supply jalousie dampers for the round connections used by WSAB, but we have also delivered square and rectangular dampers for Valmet kilns.
Adapters are available to make our dampers compatible with Katres ducts.
