The Control-A-Flow Draft Eliminator is the original commercial air deflector and diverter sold since 1995! It deflects air from overhead vents to follow the ceiling line, rather than blowing onto people. Use in a standard 2′ x 2′ drop ceiling T-bar ceiling grid. (Hard ceiling model available) Two 12″ x 24″ translucent plastic panels ride on the bottom lip of the rails and open and close like closet doors. When they meet in the middle, the air is redirected along the ceiling line, eliminating the cause of drafty air complaints. Installation takes about a minute and the only tool needed is a ladder.

The filtered model consists of two 12″ x 24″ filter panels with a wire frame sealed inside. The filters remove allergens, dust, bacteria, debris, molds and other bacteriological elements before they enter the room. The filters should be changed every 4 to 6 months, when they go from white to grey, it is time.

Draft Elimination
Cold drafts can cause illnesses, leading to costly sick time off. Draft elimination can reduce the flow of air that is expelled and the amount of those that get sick. They improve employee productivity by eliminating warming up breaks and squabbles with other employees about the thermostat settings.


Other benefits include:

Balance: For compressor systems, it preserves the air volume circulating throughout the room, while maintaining the balance of the ventilation system, without creating back pressure.

Unobtrusive: With the rail color matching the T-bars, combined with the translucent panels, Control-A-Flow® blends into the ceiling and does not stick out.

Light: The entire unit weighs less than 2 lbs.

Adjustable: Using the included “Adjusting Wand” the panels and rail cover plates can be adjusted to redirect the air in 2, 3, 4 or even 5 directions at once, while easily and safely standing on the floor.

Installation: The rails clip onto the existing T-bar and hangs below the ceiling line by only 1.5″. Requiring no tools, it can be installed in less than 2 minutes.

Versatile: Can be relocated to another area quickly and easily. Works great in laboratories to keep air from affecting scales and experiments.

Filtering the supply air has been shown to improve Indoor Air Quality (IAQ). Our filters are made of a multi-density Dacron fiber that creates one of the thinnest filters available while boasting over an 85% efficiency rating for particles 2 microns or larger. The filter is treated with EPA registered Dow Corning AEGIS anti-microbial treatment, which chemically bonds to the filter to virtually destroy bacteria and other microorganisms on contact, reducing airborne microorganisms by up to 86.5% in one pass. The filters last approximately 4-8 months and are quick, easily, and inexpensively replaced.

Reduces Illness & Allergies: By filtering out particles as small as 0.5 micron, allergic reactions to pollens, dust, rust, dust mites, Volatile Organic Compounds, and other airborne contaminants can be reduced or eliminated.

Pays for Itself: Less sick time, increased productivity and morale add up to higher profits. Saves energy by eliminating space heaters under desks.

Filters Economically Replaced: The filters last 4-8 months and replacement is a snap. Just insert the reusable metal frame into the new filter sleeve, secure end-cap and place back into the Control-A-Flow®.
