This louvered vent can be used on the side of cabinets or cabinet doors (as pictured) and where space permits. Its great for when you are housing computers or electronic components inside of cabinets and need silent cooling. It is sized for a 200x200mm cooling fan.

The louvered vent attaches to the cabinet with four screws, while the fan attaches to the cabinet from the inside. A hole must be cut into the cabinet that is 200mmx200mm in size.

Depending on how you orient the fan, it can either blow air in or out of the cabinet.
