Inspection access panel WISL
The Waterloo perforated inspection grilles are suitable for ceiling applications. They are designed to meet all exhaust air applications and are ideal for the intake of recirculation air from fan coil units.
Using a click mechanism, the grille can be easily opened and closed, allowing it to function as an inspection access panel. Optionally, the grille can be equipped with a wire mesh filter. It is also possible to replace the perforated section with a solid panel, so that the grille serves solely as an inspection access panel.
