The Expanded Mesh Grilles are designed for use in exhaust, return or supply air applications and may be mounted into walls or ceilings. They are not suitable for floor mounting. The grilles have extruded aluminium frames with a steel expanded mesh core. A large range of sizes are available.

The open area of the grille is in the range of 75-80% of the nominal area, providing maximum air flow and low noise levels.

The standard finish is white electrostatic powdercoat.
