The respiratory system of kids is really sensitive. It is very easy to get ill by even slightly polluted air.
The classroom is a confined space when the students attend class. After 40mins to 1hour, the content of the CO2 increases very high without fresh air come inside. It will make the students dizzy, sleepy, and exhausted. The students spend 6 to 8 hours per day in the classroom. It means that 1/3 of their time they are staying in the poor air quality room. If one student gets flu, it is easy to spread to others.
Nowadays, the outside air is got polluted by industry, vehicles, smog, chemicals used in science practical etc..Open the window can not make sure the income air is clear or not. It is also affected by the children’s health. Studies show that polluted air not only hampers the health of kids but also decreases the concentration power, resulting in poor grades. Moreover, it can aggravate behavioral disorders. Asthma attacks, headaches, fatigue, nausea, and rashes can put a check on the growth of kids.
Those reasons make us have to improve the indoor air quality of the classroom.

VTRONIC VT501, the wall mounted HRV with HEPA filter, is a good solution for the classroom ventilation.
With H11 HEPA filter to purify intake air
With ceramic exchanger, energy saving.
Sync control 4pcs VT501 to make indoor air balanced and efficiency
60m3/h airflow meets the classroom request
<30dB not affect students and teacher
Smart mode, reverse direction every 65 seconds.
