The Linus ProAir is a fully extruded aluminum linear slot diffuser built for architects, engineers, and contractors who need real airflow performance behind a clean architectural line. This is the three-slot model, but available for 1 to 4-slot configurations with 1/2", 3/4", and 1" slot widths. Standard and custom sizes available in any length.
100% Extruded Aluminum
No steel, no plastic, no stamping, no casting. North American-made extruded aluminum resists rust, corrosion, and moisture. At roughly 15% heavier than standard market alternatives, the difference is apparent the moment you handle it.
Aerodynamic Ice Tong Controllers
Extruded aluminum pattern controllers give up to 180° of airflow direction control — one-way, opposed, vertical, horizontal, or fully dampered. Field adjustable, and because they are aluminum rather than plastic they resist corrosion and stay quiet over the life of the install.
Three Slots, Three Openings
Three slots in 1/2", 3/4", or 1" vertical opening. More slots means broader coverage and higher air capacity for the same run length — choose the opening that meets your CFM requirement and holds your sightline.
Continuous Runs
Thirteen standard lengths in 6" increments from 12" to 84". Longer runs are joined with alignment pins for a seamless, uninterrupted line — suited to open-ceiling commercial and high-end residential work.
Field Cuttable
Ordered to length from the factory and trimmed on site with a fine-tooth, high-speed carbon blade. Up to 3" can come off each end — 6" total — which is usually enough to absorb a framing surprise during fit-out.
Slim 0.055" Faceplate
A low-profile faceplate that sits flush against the ceiling or wall, with an overall profile depth of 1.90" — worth checking against your plenum clearance before you specify.
White, Black, or Primed
Durable white or black powder coat, or a primed coat with a fine texture that takes wall paint evenly for a fully color-matched result. When painting the primed finish, mask the ice tong louver blades first.
Dimensions
Face width — three slots
| Slot vertical opening | Outside width | Inside width |
|---|---|---|
| 1/2" | 5.25" | 4" |
| 3/4" | 6" | 4.75" |
| 1" | 6.75" | 5.5" |
Profile depth is 1.90". View the full chart for every slot count and opening.
Length
Order by the nominal length shown in the size selector. The two dimensions installers ask for are derived from it:
- Overall outside length = ordered length + 1-1/2"
- Overall inside length = ordered length − 1/2"
A 48" unit therefore measures 49-1/2" overall and 47-1/2" inside. The size selector shows the overall figure alongside each length.
Mounting options
Three installation configurations, each giving a finish appropriate to commercial and architectural work. Concealed bracket adds 10% to the unit price.
Field cutting
- Units are ordered to length from the factory but can be cut on site. Use a fine-tooth, high-speed carbon blade for aluminum.
- A maximum of 3" can be cut from each end.
- Cutting both ends allows up to 6" of total adjustment.
- For adjustments over 2", slide the retaining clip against the support.
- Remove the end caps before cutting and reattach once complete.
Airflow pattern
Each slot carries its own extruded aluminum ice tong pattern controller, giving up to 180° of direction control per slot. Slots can be set independently — one-way, opposed, vertical, horizontal, or fully dampered — so a three-slot unit can throw air in several directions from a single run, or shut individual slots down entirely.
Maximum pattern controller length is 60". Units longer than that are supplied with multiple controllers per slot, each adjustable on its own.
