Anonymous users2024-01-23School toilets are usually relatively large, and exhaust fans must not be enough.
Ordinary exhaust fans have exhaust air volumes ranging from a few tens of cubic meters per hour to 3,400 cubic meters per hour.
I don't know how big the toilet in your school is, but the toilet in your school is used more frequently and is more polluted, so you should take about 8 10 air changes per hour.
So according to your description, it must be a small ventilation fan. In addition, if the design of the exhaust pipe is unreasonable, it is also very unfavorable to the elimination of toilet odor.
For public toilets, it is more appropriate to use duct fans to exhaust the air.

The school toilet is a convenient place that you often go to, and if the toilet is blocked, it will not be able to solve the problem "conveniently". >>>More
