Keeping the Environment in Schools Clean to Protect our Future

By Hugo Kurona

Today more than ever, we must focus on correct ventilation in classrooms and other spaces in schools, not only to stop the spread of COVID-19 but also to obtain ideal air quality and temperature for students. The quality of the environment that we breathe in an educational building is related to the academic performance, concentration, and comfort of the students.

Poor indoor air quality (IAQ) has been shown to have a negative effect on the attention span of school-age children, causing a noticeable drop in concentration. Mechanical ventilation is the most effective way to provide fresh, filtered air in classrooms.


Managing comfort levels within a school can be challenging, with many turning to natural ventilation as a way to improve IAQ. However, this can become a problem in the colder months 

when cold air flows into the building from outside, putting a lot of pressure on the school’s heating system.

Natural ventilation also depends on the quality of the outside air and gives you very little control over the flow of air entering the building. This is where mechanical ventilation comes in, we can avoid these problems by providing schools with much greater control over the temperature and quality of the air
flowing into classrooms, increasing the comfort and well-being of the occupants.

  • TD-125XS - TD-SILENT In-line Mixed Flow Duct Fan


The S&P TD-MIXVENT & TD-SILENT series of inline duct fans have been specially designed to maximize the airflow performance with minimal noise levels within the smallest and most compact of housing sizes. This makes the TD-MIXVENT & TD-SILENT series is the ultimate solution for small to medium-sized ventilation installations which require a high airflow to pressure ratio and occupy only the minimum space possible. Example: false ceiling voids, cabinets, and many other limited space environments.

TD SILENT As the name suggests these fans are extremely quiet, low profile “Mixed-flow” fans. Manufactured in plastic material with an external connection box, the body is easily dismantled with a full-speed controllable, single-speed motor. Sound waves are directed through the perforated inner skin and absorbed by a layer of sound-absorbent insulation. Plus the TD-SILENT is fitted with rubber gaskets on the inlet and outlet to absorb vibrations.

TD-SILENT’s compact design and low noise level make it the ideal solution for removing contaminated air from school rooms.


By using TD-SILENT In-line Mixed Flow Duct Fans, S&P USA’s Export team was able to provide a ventilation solution that kept students, teachers, and staff healthy. Additionally, the TD-Silent’s extremely quiet, low profile design made no disruption to classroom learning.
