GlasMax
- Vent with sound absorbing infill made from sustainable materials.
- The sound absorbing material filters the air flow, thereby reducing airbone irritants.
- Suited to high-rise applications.
- Three different air flow rates.
- Ideally suited for situations associated with low sound exposure.
