The deflection range of grilles are a versatile and cost-effective range, available in two models.
Both are manufactured from the same aluminium extrusions for a consistent appearance across the range.
With two banks of individually adjustable blades, double deflection grilles allow further control over throw than single deflections.
Blades are secured with high tensile spring wire, which provides enough force to keep them in their assigned position, while also allowing easy manual adjustment.
The maximum free area of 80% is identical to that of single deflection grilles, however noise generation and pressure drops are slightly higher, making Series DD double deflection grilles more suitable for supply applications.
Available in a range of standard RAL colours.
