This RS Pro range of ventilation grilles or vents have been designed for use with ventilation fans within rack server cabinets. RS Pro ventilation grilles are constructed from 0.7 mm thick 304 grade stainless steel with an electrolytic polish fine. They feature a louvred design. A vent with louvres has horizontal slats that are angled. This enables the free movement of air, but keeps unwanted elements out of the server cabinet.
The size and number of louvres varies by model. The mounting holes on each model feature a 4 mm diameter.
