Details
Designed for precision airflow control, these 10x4 inch architectural linear bar grilles feature 30-degree deflection fixed bars to direct air exactly where it's needed. Their finished aluminum construction provides added protection against corrosion* and everyday environmental exposure under typical indoor conditions.
Perfect for commercial spaces, these grilles work equally well for supply or return air in heating, cooling and ventilation systems. The 30-degree angle provides superior air direction compared to flat grilles, while maintaining that sleek, continuous look designers specify. Installation is flexible - ceilings, sidewalls or sills - though we always recommend professional installation for optimal performance.
- Perfect Fit for Targeted Comfort: Designed for a precise 10x4" duct opening, the aggressive 30-degree deflection pushes air further into the room, eliminating hot and cold spots. Please see the submittal for measurements.
- Maintain a Pristine Ceiling: Our integrated perimeter seal creates an airtight barrier, stopping dust from leaking out to mar your ceiling and ensuring a cleaner, maintenance-free appearance.
- Commercial-Grade Aluminum Build: Constructed from solid extruded 6063-T5 architectural aluminum for exceptional strength and durability, ensuring this heavy-duty linear bar grille stands the test of time.
- Durable Matte White Powder-Coat Finish: Features a sleek, matte white powder coat finish that provides added protection against corrosion* under standard indoor HVAC applications, while resisting scuffs and everyday wear to help maintain its appearance over time.
- Seamless Architectural Installation: Achieve a flawless, minimalist look with concealed mounting points designed for a clean finish. (Fasteners not included).
- Custom Airflow Solutions: This 30-degree linear bar grille can be paired with an optional custom plenum box (sold separately) to meet the specific requirements of your HVAC system for optimized performance.

*Corrosion resistance applies to standard residential and commercial HVAC applications. Performance may vary depending on environmental exposure and installation conditions. Scratching, cutting, drilling, or other damage or modification that compromises the protective finish and exposes the underlying material may reduce corrosion protection. Products are not specifically tested or rated for specialty corrosive environments, including indoor swimming pools/natatoriums, marine applications, or areas with significant chemical or salt exposure.

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!
