KW draught limiter Z 150

Precision draught limiter made of stainless steel with very high control accuracy of the negative pressure in chimneys.
With a retrofittable motor control the flap can also be used as a combined secondary air device. The draught limiter has external, self‑cleaning bearings, a locking facility in the closed position and a stop damper for reliable, low‑noise operation.
Installation can be carried out on the chimney using the KW pipe sleeve or on the flue gas pipe using the KW connection adapter.
