Cyclone Seperation Technology

EnviroVent’s Filterless Extract Fans are the only fans with patented Cyclone Separation Technology (No. 0402041.8). This ensures that all particles, humidity and dust in the air are drawn into the fan and extracted outside the property, without the need for filters that can become clogged. This enables the fan to deliver the maximum of performance to control moisture and humidity using the lowest energy consumption.

7 Year Guarantee

We are absolutely confident that we can offer a 7 year no quibble maintenance-free warranty because we have been running an accelerated life test programme for nearly 10 years on the Infinity’s predecessor – the original EnviroVent Filterless Fan without a single breakdown.4 easy steps to filterless infinity

Our R&D teams are continually testing and improving this technology to make it perform even better for longer. Following extensive testing and research we have further engineered the airflow of the Filterless Infinity with exact precision to achieve the optimal efficiency out of the highest quality bearings. The stylish new front grille allows the air to pass through with the least possible resistance to achieve the quietest performance.

Intelligent Vapour Tracking System

Running continuously on trickle, the Filterless Infinity ensures that condensation and high humidity levels are kept at bay. No user intervention is required as the intelligent vapour tracking controls constantly monitor the average humidity.

As this rises and falls, the motor speed rises and falls in direct correlation. This controls condensation both quietly and efficiently, eliminating the problem of noisy extract fans and reducing the periods of time when the fan operates on maximum speed, saving energy.

This is built into the central cartridge as standard to enable landlords to monitor operational use.



Filter-Free and Fuss-Free Cleaning

4 step cleaning couldn’t be simpler or safer:

There is a small magnet which deactivates the fan as soon as the front cover is removed. Once the cover is replaced the fan will continue to run as normal.
