Classroom Hybrid Ventilation System

To improve air quality in a naturally ventilated classroom

  • A solution for ventilating classrooms to the required standards without the need for costly renovation.
  • Supply air units draw air from outside into the classroom to meet required air changes by building regulations.
  • Smart controls monitor Carbon Dioxide (CO2) and temperature to provide a stable air quality for students and teachers.
  • Can be used to help meet the requirements of BB 101: Ventilation, thermal comfort and indoor air quality 2018.
  • Optional Heating solutions can include LPHW coils.
  • Extract Systems available to work in conjunction with supply air systems.
  • Filtration available for areas that fall within polluted areas, or roadside (AQMA) including Particulate Matter (PM10 and PM2.5) and Nitrogen Dioxide (NOx)
  • Quiet Operation (Insulated Housing and Inline Attenuation)


An easily retrofittable solution to hybrid ventilation for classrooms, or spaces when natural ventilation is insufficient to maintain an acceptable room temperature, humidity, or air quality.

Hybrid Ventilation

The Hybrid Ventilation System offers an energy efficient method of controlling temperature, humidity, and indoor air quality within a room. The system allows for the use of openable windows in conjunction with the simple mechanical ventilation by using smart control systems.

How Does Classroom Hybrid Ventilation System Work?

The Hybrid Ventilation System’s internal fan draws air from outside and mixes it with a portion of the existing indoor air to temper it reducing cold draughts. The mix can be adjusted either manually using louvres, or by using smart controls which ensure the maximum amount of supply air is utilised to optimise conditions throughout the seasons.

Installation Options

Hybrid Ventilation Systems are installed in each room that requires supplemental ventilation and should be installed as close to an external wall / window as possible ensuring minimal energy consumption and noise. These units can be installed above or below ceiling.

Smart Controls

Smart control systems can be used in conjunction with a range of monitors (temperature, humidity, and VOCs) to operate
supply and extract fans as required ensuring air quality and room conditions.

Particulate Matter Filtration (PM10 and PM2.5)

PM10 and PM2.5 Particulate air filters are optional within the Hybrid Ventilation System where outdoor air quality is poor.

Pollutant Gas and Odour Filtration (Nitrogen Dioxide (NOx), VOCs and Ozone)

Airclean Type 1 Gas Filters are optional within the Hybrid Ventilation System where outdoor levels of Nitrogen Dioxide
exceed acceptable limits. These filters have the added benefit of filtering VOCs (Volatile Organic Compounds), Ozone, and
