## ⚙️ Key Features

-   Cabin-heating air-distribution outlet
-   Designed for the Volvo Penta air-heater range
-   Connects to flexible warm-air ducting
-   Directional outlet design
-   Suitable for marine cabin installation

## 🔌 Function

The outlet directs heated airflow from the heater duct into the selected cabin or windscreen-demisting area.

## ⚠️ Common Signs of Failure

-   Restricted or weak airflow
-   Outlet cracked or loose
-   Directional vanes seized
-   Ducting detached
-   Rattling or air leakage around the mounting opening

## 🛠️ Service Notes

-   At 1.424 kg this adjustable cabin outlet is a heavier, more substantial fitting than the lightweight duct-branch nozzles sold elsewhere in the heater range — it mounts in the cabin lining or console rather than at a hose branch
-   Confirm the D11B/D11C application before ordering: this outlet is engine-specific, while the heater's branch nozzles elsewhere in the range are instead sized by duct diameter (50/55/60 mm)
