Most standard strip air vents are designed to push air directly down, but this can make working beneath such a vent uncomfortable. Linear diverters & linear diffusers are designed to divert the air flow from strip air vents, thus making the space much more comfortable. These air diverters effectively divert hard-blowing hot or cold air outward along the ceiling so it is more evenly dispersed through the room. More importantly, they do so without compromising the air flow quality of the HVAC system.
At 1800ceiling.com, we carry linear air diffusers in Stock Widths, including: 2" (for 1-slot diffusers), 3.75" (for 2-slot diffusers), 5.5" (for 3-slot diffusers), and 6.75" (for 4-slot diffusers). We also have custom widths available up to 10". All of our linear diffusers are made from 0.080 gauge high-impact white polystyrene. Item 4874 is similar to the standard linear air diffusers, but it is designed to divert air in a 45-degree pattern.
