Details
These 12x20 inch single deflection air grilles with horizontal blades provide precise vertical airflow control, making them ideal for sidewall applications where managing air rise or drop is critical. These grilles direct warm air downward in heating systems or push cool air upward along ceilings—perfect for spaces requiring targeted comfort without complex adjustments. Their streamlined horizontal blades maximize effective airflow area, reducing pressure drop and minimizing noise for quieter operation.
As a cost-effective alternative to double deflection models, these grilles offer excellent value when single-plane air direction is sufficient. Each blade adjusts independently, allowing contractors to fine-tune air distribution for seasonal changes or unique room layouts. Designed for hassle-free installation, they integrate seamlessly with standard ductwork, saving time on both new construction and retrofit projects. Whether optimizing airflow in offices, classrooms, or lobbies, these grilles deliver reliable performance with the simplicity HVAC professionals and architects appreciate.

- Horizontal Blade Airflow Direction: Equipped with horizontal blades, this vent cover offers efficient vertical airflow control, allowing you to easily angle air upward or downward to maximize comfort in the room.
- Stop Dust Streaks and Stains: Our integrated foam seal forms an effective barrier against the ceiling, blocking the air leaks that cause dirty streaks and discoloration over time.
- Clean and Minimalist Grille Design: Features a no-holes front face for a sleek, modern appearance that blends discreetly into your ceiling or wall. All mounting is handled from the sides to preserve the clean aesthetic.
- Sturdy Aluminum Construction: Fabricated from 6063-T5 architectural aluminum, this air grille provides a durable, long-lasting build that resists warping and stands up to the demands of daily HVAC system operation.
- Durable Matte White Coating: The matte white powder coat finish is designed to resist yellowing, scratches, and corrosion, ensuring your grille maintains its like-new appearance for years to come.
- Simple and Adaptable Mounting: This register arrives without hardware, giving installers the flexibility to choose their preferred screws or anchors for a secure fit on various wallboard or plaster surfaces.

Bought 2. Easy to install. Nice to
buy from a local BC company.
Excellent quality, well built. Good delivery. All good.
We moved to a house with the cheapest builders-grade cold air return grates/grilles/registers. The layout of the house put them in very visible locations. While looking for an upgrade, I discovered the insanely high prices for something better looking. Then I put the words “diffuser” and “Canada” in my search. Linear Air Diffusers had exactly what I wanted! Well made, high quality, adjustable grilles. An exceptional value, I immediately ordered three. (Yes they work as intakes too). Perfect fit for the 10x16 openings. Installed with Velcro for a screwless custom look. Adjustable vanes helped with furnace noise in one of the bedrooms. Couldn’t be happier.
We have used these on several jobs and are extremely pleased with the way they Proform and the look. Last job we installed these in a large church to project the air to better stir the air in the room and the worked very well as planned.
Good as promised, good as expected.
I’m a returning customer for a few reasons... Sturdy construction, easy installation, the vents show up as ordered, and good communication. Highly recommend!
Quick shipping, product as advertised, would recommend.

Awesome, exactly as advertised.
I recently purchased linear air diffusers and couldn’t be more satisfied with the entire experience. The quality of the product is absolutely top-notch—sleek, durable, and designed to perfection. They added a modern and clean look to my space while performing exceptionally well.
There was a slight mix-up with my order, but I was incredibly impressed with how efficiently and professionally it was handled. The issue was resolved quickly and at no extra cost, showing their dedication to customer satisfaction.
Shipping was also impressively fast, and the diffusers arrived well-packaged and in perfect condition. I highly recommend these diffusers and this company for their excellent products and outstanding service!
Smooth communication from beginning till end. Highly recommend, very professional.
