Plastic Diffusers

Non-corrosive plastic ceiling registers, vents and air returns are ideal for wet and humid areas such as kitchens, locker rooms, showers, indoor pools, dishwashing areas and medical MRI rooms. Larger 2'x2' are made to be installed into a ceiling grid system while our smaller 12" x 12" plastic vents are ideal for rest rooms and showers.

Black soot and dust on your ceiling tiles can be expensive and difficult to clean or replace. Avoid damage to the ceiling tiles surrounding your ceiling diffusers by installing our unique ceiling dust deflectors. 1800ceiling.com carries many innovative repair products and even offers How-To videos for the do-it-yourselfers.

Air Diverters

Block and redirect annoying drafts from square 2'x2' ceiling diffusers and linear ceiling vents. Our diverters install quickly without the need for tools. Stay comfortable while sitting at your work station. Ideal for offices, restaurants, commercial kitchens and medical facilities.

Linear Deflectors & Diverters

In some commercial buildings, the HVAC systems blow air so forcefully that the excessive hot or cold air can cause a reduction in work performance and employee morale. Linear diffusers are specially-designed to solve that problem. These products divert unwanted, constantly blowing air away from populated areas with a 45-degree deflection so the air is distributed more evenly through the space. The result is a more seamless indoor environment that's more comfortable and pleasant.

1800ceiling.com carries a wide selection of HVAC products for building managers, physical plant warehouses, HVAC contractors, and other professional tradesmen. We have linear slot diffusers available in a range of lengths so you can find the perfect fit for every project. Shop online today and stock up, because the more you buy the more money you'll save!
