Datalogging & Variable Speed Control

The Datalogging function enables the collection of data such as the total running time at trickle and boost speeds, the  time in which the fan has spent in periods of increased humidity and the energy that has been used.

The Infinity speed can be varied for more control and to achieve increased airflows.


  1. Helps protect against disrepair cases
  2. Reduce complaints about condensation and mould
  3. Provides clarity on the running costs and energy usage

Cyclone Separation 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.

  1. Air is expelled through robust rear chamber
  2. Air is thrown outwards through a dual powered expansion chamber and allowed to expand out to atmosphere
  3. Easy clean impeller
  4. Air is drawn through the helical front grille

8 Year Renewable Warranty

Part of our lifetime range®. High quality for peace of mind, saving time, money and hassle. Reducing the impact on landfill sites too.

Precision Engineered

We are absolutely confident that we can offer a 8 year 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.

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.

Intellitrac® Controls

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 Intellitrac® Technology 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.

One Fan For All Situations

The Infinity is ideal for WC, bathroom, kitchen and utility room installations, delivering high performance extract ventilation to meet the building regulations and beyond.

From simple through the wall installations, to in-line, window and ceiling installations, the Infinity fan fits all with the use of easy to install accessory kits.

For extra safety in bathrooms, a low voltage version is available.

Easy Cleaning In 4 Steps

The fan has been designed for ease of cleaning and servicing in mind. That is why it can be carried out safely and quickly by the resident.

There is a small magnet which deactivates the fan as soon as the front grille is removed. The impeller can then be cleaned in a sink and the fan scroll can be wiped clean with a cloth quickly and easily.

Once the impeller is inserted again and the front grille replaced, the fan will continue to run as normal. No more unsightly fans with clogged filters.
