FAQs
What is a dMEV fan?
A dMEV fan (like the ARIA) continuously extracts damp air from wet rooms, providing constant, low-level ventilation to prevent mould, condensation, and maintain regulatory compliance.
Is the ARIA® dMEV fan compliant with the new Building Regulations Part F (2022)?
Yes, fully compliant. The ARIA dMEV system is engineered to exceed the required continuous extract rate for wet rooms under the latest Part F guidelines. Your installer will need to complete Appendix C of the Approved Document to demonstrate the fan has been installed and tested correctly.
How does a dMEV system like ARIA® differ from a standard intermittent extractor fan?
A standard fan reacts after moisture is visible. ARIA is a continuous, demand-controlled system that runs 24/7 at a low rate. This prevents the build-up of humidity that causes condensation and mould in the first place, offering guaranteed protection.
What do I need to show my Building Control Officer to guarantee Part F acceptance?
Your VENTI Air Passport or the Approved Document F Appendix C. Simply submit this document to your inspector for instant confidence.
How silent is the ARIA fan, and will it disturb sleep?
The ARIA is engineered for minimal acoustic impact. At its continuous trickle rate, the fan runs at a level that is quieter than a whisper, ensuring you enjoy silent, continuous air quality without any disturbance.
How difficult is it for my electrician/builder to install the ARIA fan?
Installation is highly efficient. As a decentralised (ductless) system, ARIA saves significant labour time by eliminating the need for complex, messy ductwork required by central systems. The unit simply installs directly through the wall.
Does the ARIA fan really help prevent mould and condensation in wet rooms?
Yes. The core function of ARIA is to continuously maintain a low relative humidity (RH) in the room. By constantly removing damp air, it prevents condensation on cold surfaces, thereby eliminating the environment mould needs to grow.
How often do I need to clean the ARIA fan unit?
Maintenance is deliberately simple for the homeowner. The front fascia or filter is designed for a 60-second, tool-free removal and wipe down. We recommend inspecting the filter every 3–6 months depending on usage.
Why does the ARIA fan look better than other plastic dMEV units?
ARIA is designed specifically for the high-end refurbishment market where aesthetics matter. Its minimal profile and clean lines ensure it blends seamlessly into your interior and exterior façade, providing invisible performance that respects your design.
What is the warranty period for the ARIA dMEV fan?
We offer a competitive 10-year warranty on the ARIA unit, a testament to the robust engineering and high-grade components used throughout the system. Please register your fan using the information provided in the box.
