Ventilation & Continuous Running Extractor Fans

A continuous running extractor fan operates at a low background speed throughout the day and night. It provides steady ventilation and can boost when humidity rises, helping remove moist and stale air from the property.

No. Continuous running fans are designed to be highly efficient and run at low trickle speeds. Energy use varies by model, but they are generally much cheaper to run than many people expect.

Most continuous fans are designed for quiet background operation. Because they usually run at a low speed, they are often less intrusive than older intermittent fans that switch on loudly at full speed.

Continuous fans can help reduce condensation by removing moist air before it settles on cold surfaces. They are especially useful in bathrooms, kitchens, en-suites, toilets and utility rooms.

Current Part F Building Regulations focus on providing suitable ventilation. Continuous running fans can help meet ventilation requirements when specified and installed correctly.

Continuous ventilation is commonly used in bathrooms, kitchens, en-suites, utility rooms and toilets. These rooms produce moisture and often need reliable extraction to prevent condensation and mould.

In many cases, yes. Replacing an old bathroom fan with a continuous running fan can improve moisture control, reduce condensation and provide better everyday ventilation.

dMEV stands for decentralised Mechanical Extract Ventilation. A dMEV fan provides continuous low-level extraction from individual rooms such as bathrooms, kitchens and utility rooms.

Yes, they can help. Black mould often grows where excess moisture and poor airflow are present. Continuous ventilation helps reduce humidity and makes it harder for mould to keep returning.

The best fan depends on the room, required airflow, humidity control needs and installation type. Fans with humidistat control are often a good choice for bathrooms and other damp-prone rooms.
