GONAL 0462 plastic fix grille 230x430

OUTDOOR PROTECTIVE GRILL: One of the possible elements of the outlet end point of the ventilation system (e.g. ventilation fan, hood, etc.). The protective grid with low pressure loss and free of moving elements provides rain protection and protection against physical impact, it can be installed on both vertical and horizontal surfaces. The protective grid does not have a pipe socket, so it can basically be fitted to rigid-walled ventilation pipes that are led out to the plane of the outdoor surface. Applicable: at the end of ventilation systems with a diameter of 220 mm or rectangular duct elements, placed on the external side wall.
