Industrial Single Blade Dampers

The simplest of flow restrictors as their control is due entirely to producing an increase in system resistance to reduce pressure or volume.

Most effective when used as an open or closed device. Our Blade form ensures very little pressure drop across the blade and good flow characteristics downstream.

Not suitable for modulating control as the volume passed rises very quickly as the damper starts to open, and little change is produced over the last 30 degrees of opening.

With a damper of this type partially open, the flow downstream is very turbulent, initially with little of the mass flow down the centre of the duct. It takes a length of about 10 duct diameters for the flow to homogenise.

They can be supplied for high temperature operations and supplied like all our dampers with Actuation and controls to suit any exacting requirement.
