Indoor Air Quality

Poor indoor air quality can seriously affect our health and wellbeing. Whether it is inside homes, hospitals, schools or offices, effective ventilation systems guarantee removal of excess moisture and airborne pollutants, leaving a clean and fresh air environment. As energy resources become scarcer, regulations become tighter and the awareness of the environment issues relentlessly increases. Hence, the importance of well-specified ventilation systems. Moreover, in the light of the current coronavirus pandemic, it is now crucial to improve ventilation in order to prevent and minimise the spread of coronavirus in indoor spaces.

Which extractor fan should I get?

Building Regulations Approved Document F – Ventilation, sets minimum flow rates that a ventilation system installed in a wet room should be able to deliver when correctly installed. The minimum Airflow rates are as follows:

  • 6 l/sec for toilets
  • 15 l/sec for bathrooms
  • 30 l/sec for utility rooms
  • 60 l/sec for kitchens (30 l/sec in kitchens when the fan is installed adjacent to the hob – this is also the minimum flow rate expected from a ducted cooker hood)
Indoor Air Quality

Having considered the application of the ventilation required it is important to select the correct type of fan to meet the requirement fully.

Axial Fans are ideal for through the wall, ceiling and short run of ducting applications. While providing high performance from a slim profile, they work against limited backpressure. They are therefore recommended for use with flexible ducting not exceeding 1.5m in length with a maximum of two 90 degree bends.

Mixed Flow Fans for wall and ceiling combine the convenience of an axial fan size with the performance of a small centrifugal fan. Thus, they are ideal for short to medium duct runs.

Centrifugal Fans are quiet, powerful and suitable for wall and ceiling applications. They work well against system resistance making them the perfect choice for efficient performance for longer duct runs.

Safety Low Voltage Fans (SELV) Axial, Mixed Flow and Centrifugal Fan variants operating from 12v or 24volt supply which may be installed in accordance with IEE wiring regulations.
