Vent-Axia 473827 Lo-Carbon Centra HT DC dMEV Centrifugal Fan with Humidistat & Timer

The Vent-Axia 473827 Lo-Carbon Centra HT DC is a high-performance decentralised Mechanical Extract Ventilation (dMEV) centrifugal fan designed for continuous residential ventilation in bathrooms, kitchens, utility rooms and toilets.

Featuring an integrated humidistat and timer, this energy-efficient 100mm fan automatically responds to increased moisture levels to help control condensation and improve indoor air quality. Its near-silent operation and discreet styling make it ideal for modern homes and social housing applications.

What is dMEV?

Decentralised Mechanical Extract Ventilation (dMEV) provides continuous low-level extraction directly from wet rooms such as bathrooms and kitchens. Unlike centralised systems, individual fans operate independently to deliver effective whole-house ventilation in accordance with Building Regulations Approved Document F.

The Lo-Carbon Centra continuously extracts stale and moisture-laden air at low noise levels, helping to reduce condensation and improve indoor air quality throughout the property.
