Dayus DABL and DABLD Bar Linear Grilles - Made to Order

A grille is a vent cover through which air is blown into or out of a room for circulation back to the central heating or cooling unit. These are commonly found if you have heating or central air conditioning. A grille has no damper to control air flow, so air is left to flow freely. Grilles do not have the damper normally found on registers.

General Information:

2 Slot Ac Grill

General notes on the quick selection table:

For supply or return air, fully adjustable loose core linear slot diffuser with unique air pattern control design. The air pattern can be adjusted in situ or factory, set to suit design requirements. It is suitable for ceiling mounting applications. The loose core linear slot diffuser's unique design allows the installer to simply push the complete core of the diffuser upwards to allow it to be screw fixed to the box above then simply dropped back down into the frame.

For the selection tables with lateral discharge:

• The diffuser is located along the longitudinal axis of the ceiling, next to the wall, in a room of the following size:

• The air jet is adherent (Coanda effect), i.e., the diffuser is mounted flush with the ceiling.

For the selection tables with vertical discharge:

Ac Slot Grill Picture

• The diffuser is located in the middle of the ceiling in a square room.
• Positioning for vertical discharge, as non-adhering jet.
• The diffuser length is less than 0.5 times the width of the room and less than 0.5 times the throw.
• The pressure P_t is measured inside the duct upstream of the plenum box.
• The height of the room is 3 ± 0.5m
• The ΔT is equal to -10°C, the temperature difference between the room and the supply air.
• The maximum velocity is 0.25m/s in the occupied zone.

Ac Grill Slot Diffuser

Correction factor for width to length ratio of the room ( applied on both 20 & 25mm ).

3 Slot Ac Grill

The factor is known as C_a. To calculate, divide the diffuser width less length by the length of the room. This is applicable to linear slot diffusers with lateral discharge. In diffusers with vertical discharge, C_a is equal to 1, since these diffusers have been tested in a square room (A/L =1) .
