The Eggcrate Grille is the most commonly used in ceiling mounted return air applications, they are not suitable for floor mounting. The grilles have extruded aluminium frames with a 13mm x 13mm x 13mm aluminium egg crate core. The standard inner core is removable with options to order either a “push up” type or alternatively a “pull down” type. Hinged models are available as standard and provide easy access to filters or other equipment. There is a spring retaining clip for easy fixing.

The free area of the grille is >90% of the nominal area, providing maximum air flow with relatively low noise levels. The standard finish is in white powdercoat.

Air Filtration: A filter is offered as a standard option in removable core grilles. This filter is easily removed for cleaning, easy access or replacement. The filter media is manufactured in a synthetic nonwoven material. It offers low air resistance, long life and satisfactory dust extraction efficiency.
