Sub Floor Fan Elta MORI WMF100 – Extract Pulls The AIR OUT (Mains Powered)
Low-Energy Weatherproof Subfloor Extract Fan for Damp, Humidity, Condensation and Airflow Control
The Elta MORI WMF100 Sub Floor Extract Fan is a low-energy, mains-powered ventilation solution designed to improve airflow beneath suspended timber floors by actively pulling stale, humid air OUT of the subfloor void.
Unlike passive air bricks, which rely on natural airflow, the Elta MORI WMF100 provides continuous mechanical extraction to help reduce excessive humidity, condensation and stagnant air in difficult-to-ventilate underfloor spaces.
Poor subfloor ventilation can result in moisture accumulation, musty odours and conditions that encourage mould growth and timber deterioration. By removing stale air from beneath the property, the WMF100 Extract Fan helps promote more effective air circulation and improved ventilation.
Featuring an energy-efficient motor, adjustable low-running and boost speeds, and weatherproof construction, the Elta MORI WMF100 is suitable for a range of residential and refurbishment applications.
For a more complete subfloor ventilation solution, the WMF100 Extract Fan can be paired with the matching Elta MORI WMF100 Supply Fan, which pushes fresh external air into the subfloor space.
