Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:

Create a detailed description for the following product: BAL 150, belonging to category: External Exhauster

### Response:
This innovative external exhauster automatically opens when the hood is switched on and the extracted air is conducted to the outside below the sloping front panel. Thus, cooking in the kitchen is remarkably quiet. When the exhaust air duct is closed it is reliably soundproof and thermally insulated. The minimalist looking housing of the weatherproof fan is made of stainless steel. Different glass colours are available for the decoration of the front cover.
