Ultra-Quiet and Energy-Efficient: Operates at an exceptionally low noise level of just 10dB, making it the quietest dMEV extractor fan available. Powered by a highly efficient 24V DC motor, it consumes as little as 1.21W at trickle speed.

Customizable Speeds with Powerful Boost: Offers installer-selectable trickle speeds of 6/8/13 l/s and a boost mode up to 22 l/s, activated by a pull cord or remote switch. The timer overrun allows boost to run for 2, 15, 30, or 45 minutes, providing optimal control for air extraction.

3 Years Warranty: The sleek circular design blends seamlessly into any room, combining aesthetics and practicality. Built to last with high-quality materials, backed by a 3-year warranty for reliable, long-term performance.

Advanced Performance Features: Equipped with a flow sensor to maintain constant extraction rates under varying conditions like wind pressure. With a Specific Fan Power (SFP) as low as 0.13 W/l/s, it ensures compliance with building regulations while minimizing energy consumption.

Durable, Safe, and Easy to Set Up: Designed with an IPX5 rating for wet conditions, suitable for wall or ceiling installation. Includes LED diagnostics for easy setup and fine-tuning of settings. Power interruption memory ensures no loss of configuration, and the fan is ideal for both new builds and retrofit installations.

Ultra-Quiet and Energy-Efficient: Operates as low as 10dB for silent performance, powered by a 24V DC motor consuming just 1.21W at trickle speed, making it cost-effective to run at under £1 per year.

Adjustable Humidity Control: Intelligent humidity sensor activates boost mode when humidity reaches 60-90% (adjustable) and returns to trickle speed when levels drop, ensuring optimal moisture management.

Customizable Speeds and Boost Mode: Features selectable trickle speeds of 6/8/13 l/s and a powerful boost mode up to 22 l/s, with boost duration adjustable to 2, 15, 30, or 45 minutes for maximum flexibility.

Advanced Features for Reliability: Equipped with a flow sensor to maintain constant extraction rates under all conditions. Retains settings during power interruptions, ensuring continuous, hassle-free operation.

IPX5 Rated with 3 Years Warranty: Durable and safe for installation in wet areas, with a compact circular design suitable for wall or ceiling mounting. Backed by a 3-year warranty for long-lasting performance.
