Airvent 477633 125mm Mixed Flow Fan

The Airvent Mixed Flow Fan offers high-performance air extraction for restricted spaces, making it the perfect solution for ventilation needs in refurbishment projects.

Unparalleled performance in confined spaces

The mixed-flow impeller sets this fan apart. Drawing air parallel to the fan's axis and expelling it perpendicularly, this configuration creates more pressure and higher airflow than traditional axial fans. This allows sufficient ventilation through convoluted duct routes or highly restrictive outlets like external wall grilles. With airflows up to 500m3/h on high speed and pressure capabilities exceeding 100Pa, this fan can overcome restrictions that would overwhelm lesser models.

Despite its powerful performance, noise levels are impressively low thanks to the fan's high-quality components. It produces just 35dB(A) at 3 metres, even on the highest speed setting. With its range of speed settings, you can reduce noise even further, down to 21dB(A) on low.

Optimised design for challenging installs  

Installing ventilation fans in refurbishment projects often means dealing with cramped loft spaces and inadequate mounting points. This fan is purpose-built for those difficult situations.

The integral foot plate provides a secure anchor point for installation on joists or framing in confined loft spaces. With large slots allowing screw-fixing adjustability, mounting the fan is quick and straightforward. The spigot is designed for rapid flexible ducting connection, enabling you to easily route air through tricky loft spaces to an external vent.

The fan's compact 230 x 175 x 260mm size allows it to squeeze into tight spaces between joists. Its robust IPX4 rating also means it will cope well with the challenging conditions in loft spaces. With its optimised design for rapid installation and reliable performance, this mixed-flow fan is the ideal ventilation solution for renovations and upgrades.
