FAQs
A dMEV (decentralised Mechanical Extract Ventilation) system provides continuous, 24/7 demand-controlled air extraction specifically for wet rooms like bathrooms, kitchens, and utility areas, operating on a single-room basis with automatic humidity response—running on low trickle speed (e.g., 5 l/s) and boosting extraction (up to 50 l/s) when moisture exceeds 65%, then reverting to background mode after stabilization, all while maintaining ultra-quiet operation (as low as 9 dB) and energy efficiency (1.0–5.8W).
Unlike traditional intermittent fans that shut off prematurely, dMEV units like the ARIA example prevent damp, mould, and indoor pollutants by ensuring persistent moisture removal, feature manual boost override via light/motion switches, and suit both retrofits and new builds with integrated ducting solutions for seamless installation.
