How does a MEV system work?
A continuous Mechanical Extract Ventilation (MEV) unit sits centrally, usually in a loft or cupboard, and quietly extracts stale, humid air from wet rooms (kitchen, bathrooms, WCs) through ducts, expelling it outside. Running continuously, it controls moisture and pollutants across the whole home.
What is the MVDC-MS designed for?
It's designed for the simultaneous ventilation of separate areas in the home, or as a multi-point extractor for commercial applications. It offers 'Close Control' of ventilation rates for accurate, efficient performance.
Does it have humidity control?
No, this is the standard multi-speed model. If you'd like the unit to boost automatically on rising humidity, choose the MVDC-MSH humidity version (443298B).
How is the speed controlled?
It has fully variable normal and boost speeds via a switched-live activation, plus a third purge speed on a second switched live. A potentiometer speed selector lets you set the exact airflow, reducing noise and energy use.
Where can it be installed and is it noisy?
It can be wall-, ceiling- or loft-mounted at any angle, and an acoustic lining is fitted as standard to keep noise levels low.
Does it meet Building Regulations?
Yes, it complies with Building Regulations Approved Document F (System 3) and is recognised in the SAP PCDB with best-in-class Specific Fan Power. It carries a 2-year warranty and should be installed by a competent person.
