Egg Crate Grill

The Series 51EC Eggcrate Return Grilles are high capacity return or exhaust outlets with the highest freearea available (approximately 90%). They therefore have the lowest pressure drop and sound levels available for a return airinlet.

The aluminium cube cores are constructed of thin, interlocked aluminium strips assembled in a square grid fashion and match in appearance the grid louvres on parabolic light fixtures. They are most suitable for use as ceiling returns. They are not recommended for low side wall applications due to potential core damage.

The 51EC Series are available with various frame/border styles to suit both lay-in type and hard ceilings.
