NCA Single blade balancing dampers are designed for use in circular ducting to allow airflow to be adjusted or balanced.
They are ideal for use as balancing dampers for branch ducts to individual grilles.
The lockable hand control shows blade position from 100% to 0%.
N.B.These dampers are not suitable for applications where the duct needs to be completely shut off, as there is no seal around the blade.
Also available with extended spindle for motorisation – please contact us to order.
