Product Overview

Double Deflection Grilles have two sets of individually adjustable blades – a front set of horizontal blades and a second set of vertical blades set at 90 degrees to each other.

Gaps between the blades are sufficient to allow easy adjustment of blades, enabling the user to create custom blow patterns. Whether these be targeted towards one area, or fanned out to affect a wider area is entirely your choice.

As noise generation and pressure drops are slightly higher than with a single deflection grille, the double deflection grille is better suited to supply air applications.

All square sizes from 150sq – 550sq rising in 50mm increments are held in stock. Standard stocked grilles are powder coated to RAL 9010 (Pure White). Rectangular grilles and anodized finishes are made-to-order, usually within 5 working days.

Opposed blade dampers can be factory fitted to your double deflection grille. Adjustable through the grille blades with a screwdriver, opposed blade dampers allow easy volume control.

The Double Deflection Grille can also be made-to-order in sizes other than the standard sizes listed.

The smallest dimensions available are: 100mm x 100mm (W x H).

The largest dimensions available are: 2900mm x 2900mm (W x H).

For blade lengths above 570mm mullions will be used.

Application

Double Deflection grilles are better suited for use as supply air outlets in a variety of settings including ceilings, walls and ducts.

Having a second row of blades reduces the free area by around 10%, therefore we do not recommend using a DD for extract purposes.

Construction

Fabricated entirely from extruded aluminium. Two rows of adjustable blades set within a frame. Blades held in place with high tensile spring wire and starlock washers.

For overall size including flange, add 45mm to width and height.

CVDDG - Sizing

In order to calculate the exact overall face dimensions of the grille +45mm must be added to the nominal dimensions.

Nominal Dimensions = Opening Size.

This is the number shown in the part codes e.g. CVDDG-600

For example:

CVDDG-600: The nominal opening size is 600mm x 600mm. The overall size including frame is 645mm x 645mm.

Actual Neck Size: For clearance within the aperture a standard tolerance of 15mm (7.5mm each side) is deducted from the nominal opening size listed.

For example:

CVDDG-600: The nominal opening size is 600mm x 600mm. The actual neck size is 585mm x 585mm.
