 Door Grille  A to Z Products
 Introduction
 
Door grilles are commonly known as Privacy Grilles and are used to allow air movement between multiple treated spaces. They are non‐vision door fixed grilles. Door grilles are used in any heating, ventilation and air conditioning system (HVAC). It can be used as transfer grilles for walls and partition openings and its architectural finish is eye catching. They are used in dark rooms where light sensitivity is critical. They are applicable where low pressure air with sufficient flow needs to be achieved thus eliminating draughts.

Door grilles have a simple design which makes them useful for incorporation in all styles of architecture. Their special features make them ideal for placing in doorways.

COSMOS Door grilles are suitable for mounting in doors to allow ventilation air to pass between adjacent
rooms. They are used in doors to allow air flow to a space that is not directly served by a ducted source of supply air or a ducted outlet for return or exhaust air.

COSMOS series DG door grilles are designed to transfer air through door or wall. The DG series includes inverted “V” shaped louvers providing a sight proof return or exhaust grille regardless of the viewing angle.

The inverted “V” shaped profile of the blades allows the passage of air but prevents light from entering, and at the same time reduces the sound pressure level.

The series DG is available with a number of options that include a light proof option, surface mounting applications and door mounting.

Also series DG offers a number of solutions for your door and air transfer applications.
