Question:
Does this need a duct from the ventilation fan? I have a ventilation fan in my shower room and wondered if it needed a duct to take the condensation out to this Ubbink oft4?
Answer:
The Ubbink OFT4/166 Flat Roof Vent / Terminal is designed to facilitate ventilation in flat roofs. Typically, it's used in combination with a duct system to transport air from the interior of your property to the outside. This would include air from a ventilation fan in your shower room. It's important to have this kind of system in place to efficiently handle condensation and maintain good air quality. However, the specifics of your setup, including the need for a duct between your fan and this vent, may depend on various factors. We recommend checking with a professional installer or our sales team for advice tailored to your situation.
