ARIOSA
Ariosa is Valsir's heat recovery ventilation system with solutions for both centralised and apartment-level ventilation. The range covers the vertical Ariosa V and Ariosa V Compact, the Ariosa HV for horizontal or vertical installation, the apartment-level Ariosa DOT and DOT Mini, and the room-level Brezza60. Air distribution uses the AriaSilent duct system. All units have an LCD control panel as standard, and the system can be controlled remotely with the VMC app, available on the App Store and Google Play.

ARIAPUR
Ariapur is an odour and vapour extraction fan with two extraction paths: through a wall or ceiling grille and directly from the WC pan via the flush pipe. It connects to the drainage vent stack and needs no separate exhaust duct; a non-return valve prevents backflow. Available for Tropea S and Winner S frame versions.
Product information
- Dual extraction: room air via the grille and odours straight from the WC pan
- Adjustable capacity: 65–80 m³/h (Ariapur 80 / 80 T) and 85–100 m³/h (Ariapur 100 Led)
- Non-return valve prevents odour backflow; several units on one vent stack
- Switch or motion-sensor activation; 2–30 min timer completes the air change
- Ariapur 100 Led: integrated 12 W LED light, 4000 K, 960 lm
