Vent-Axia Lo-Carbon Tempra 100mm (4") Heat Recovery Fan Longer Cell & Pullcord - 403832

Product Overview

This model is a “long-cell” (L) version of the Tempra LP range, designed specifically for wall thicknesses between approximately 321 mm and 460 mm. It fits through a standard 100 mm diameter hole, making it well suited to refurbishment of bathrooms, toilets, kitchens or utility rooms where replacing an existing 100 mm fan is desirable.

The unit provides heat-recovery functionality, extracting stale air and transferring its warmth into the fresh incoming air via a compact ceramic heat-exchanger achieving up to around 78 % temperature efficiency. It supports continuous trickle modes of approximately 6 l/s or 9 l/s, with a boost capability of circa 15 l/s, offering both background ventilation and intermittent higher extraction when required.

Control is via a pull-cord mechanism that activates the boost mode when needed (for example when someone enters the room), making it intuitive for end-users. The unit is IPX4 rated for bathroom safe use and features a “summer setting” (extract only) to prevent overheating in warmer periods. Its EC/DC motor is low-power (trickle consumption from approx 3.2 W) and very quiet in operation, promoting energy-efficient, discreet performance.
