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 single-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 Slot Openings
1/2", 3/4", and 1" slot vertical openings, so you can hit your CFM requirement and still hold a consistent sightline across a space. The face width changes with the opening — see the dimensions below.
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 — single slot
| Slot vertical opening | Outside width | Inside width |
|---|---|---|
| 1/2" | 2.75" | 1.5" |
| 3/4" | 3" | 1.75" |
| 1" | 3.25" | 2" |
Profile depth is 1.90" across all slot openings. View the full chart for 2, 3, and 4-slot widths.
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.
