Please find below shopping carts for eggcrate grilles including options for grilles only using the ceiling void as a return air plenum (used when the void is part of the conditioned space). Additional options are for eggcrate grilles with boxes with one or more spigots on (more than one return duct can be connected to one grille to minimize the number of return grilles required, see grille selection or plenum selection charts). Eggcrate grilles can also come complete with hinged cores and filters as an option when fan coil accessability is an issue.

When you have purchased your grilles with a grille box a "Confirmation order form" will automatically be sent by email for you to confirm spigot sizes and positions you require.



MEC metal eggcrate grilles only, no boxes

MEC white metal eggcrate grilles are for mounting within either a MF plaster board ceiling or within a ceiling grid (the 595mm x 595mm version directly replaces a 600mm x 600mm ceiling tile and the 1195mm x 595mm replaces a 1200mm x 600mm tile). grilles only are used for non ducted return air applications that use the ceiling void as a return air plenum. These diffusers are designed to provide minimum air resistance and are constructed from aluminium and are finished in RAL9010 white and all prices include delivery costs.
