Rytons 9×6 Cowled Acoustic AirLiner Set with Hit & Miss Ventilator | Telescopic Cavity Liner | 9,800mm²
The Rytons 9×6 Cowled Acoustic AirLiner Set is a telescopic cavity wall ventilator system with an external cowl, providing the same acoustic and ventilation performance as the standard 9×6 AirLiner Set with the addition of improved weather resistance at the external face. The cowl deflects wind-driven rain from the vent opening and reduces wind-induced noise, making it the appropriate specification for exposed wall faces or prevailing wind elevations. Acoustic performance is 42 dB open or closed. Equivalent area is 9,800mm². Manufactured from UV-stabilised high-impact polystyrene and polypropylene. Cowl dimensions: 255mm L × 154mm H × 74mm D. Sleeve: 220mm W × 140mm H, extending 250mm to 404mm. Internal grille: 271mm L × 171mm H. Available in Terracotta, Buff/Sand, and White.

Applications
- Background ventilation with improved weather resistance — exposed or wind-driven rain locations. The external cowl deflects wind-driven rain away from the vent opening, making the cowled variant the appropriate specification for exposed wall faces, prevailing wind elevations, or locations where the standard flat external grille would be subject to water ingress. The cowl projects 74mm from the wall face — confirm clearance from adjacent features before specifying.
- Replacement of existing non-acoustic ventilators in 9×6 openings. Fits standard 9×6 inch (229×152mm) ventilator brick openings. The telescopic sleeve adjusts from 250mm to 404mm.
- Hit & miss control — ventilation management. The hit & miss ventilator grille allows the occupant to open or close the vent to control airflow.
Product Benefits
- 42 dB open or closed — BRE tested to BS EN 13141-1:2004.
- External cowl — improved weather resistance. The projecting cowl deflects wind-driven rain from the vent opening. Cowl dimensions: 255mm L × 154mm H × 74mm D.
- 9,800mm² equivalent area — same ventilation performance as standard variant.
- Telescopic sleeve — adjusts 250mm to 404mm.
- Hit & miss ventilator — occupant-controlled airflow.
- UV-stabilised high-impact polystyrene and polypropylene.
- Three colour options — Terracotta, Buff/Sand, White.
Installation
As the standard 9×6 AirLiner Set. The cowl is fitted to the external face of the sleeve in place of the flat external grille. Ensure the cowl projects clear of the wall face and that there is adequate clearance from adjacent wall features. The cowl opening should face downward to deflect rain — confirm correct orientation before fixing.
