Controlled ventilation for an effective workplace

Amphenol Advanced Sensors CO2  Wall Mount  Ventostat 8000 Series

Having air that is fit to breathe might sound like a fundamental human right but, until comparatively recently, clean air was more of an ideal than a daily reality.

Atmospheric conditions

In the 21st century, we understand that true air quality is about much more than dividing the acceptable from the unacceptable. Proper heating and ventilation are recognised as vital aspects of buildings where people can live and work in comfort, and be productive. Environmental legislation is being enforced to guarantee cleaner air that is free from toxins. Having the right tools to measure air quality levels accurately is an important part of building maintenance.

Making a measurable difference

CO2 (carbon dioxide) is what we breathe out. Measuring its proportion is a good test of occupancy rates and air quality. Modern microelectronics has produced sensors that monitor and control air quality and do not require constant recalibration to stay within acceptable tolerances.

For example, when more people are in a building the oxygen levels will be depleted, so CO2 detection can be set to trigger the air conditioning to maintain oxygen at a comfortable level.

Telaire from Amphenol Advanced Sensors

The new Ventostat 8000 series, manufactured by Amphenol Advanced Sensors and supplied by Acal BFi, measures temperature, CO2 content and humidity via one cost-effective transmitter unit. This allows building managers to easily control the incoming fresh air and not only maintain excellent air quality but also reduce over-ventilation and the heating and cooling of that excess air. Building owners and HVAC contractors who deploy this demand control-based ventilation strategy report savings of up to 20% on their ventilation costs.


  • Uses a DCV approach (demand controlled ventilation).
  • Easy to install.
  • Low cost.
  • Saves money by making your ventilation system more effective.
  • Self-calibration option saves further costs.
