HVAC Egg Crate Diffusers

HVAC Egg Crate Diffusers

HVAC egg crate diffusers and louvers enable your HVAC system to work more efficiently because they allow for optimum air low with minimal resistance. Unlike traditional slotted vents, single cell air louvers provide greater air intake capacity because they don't collect dust and debris as quickly. The greater air flow means your HVAC system will run easier and longer. The result is more balanced air flow through the structure and a longer lifespan for your expensive HVAC system.

1800ceiling.com offers an extensive inventory of egg crate air louvers and light diffusers so you can find the perfect solution for your project's needs. We carry aluminum sight guard grilles, plastic perforated tile returns, and a variety of different egg crate lenses. If you want an economical alternative to the traditional light panel lenses or air intake vents covers, then shop our selection of egg crate louvers below.
