What does an extractor fan rate mean?
What does an extractor fan rate mean and how can I tell what applies for any given fan?
Expert Trade Answers
Best Answer
"The extraction rate refers to the amount of air that the extractor will remove, this is usually measured in cubic metres per hour. As a rule of thumb the bigger that number is the better the extractor is. Something else to consider is the noise levels, the lower the dB is the quieter it will be."

"Use the extractor rate to determine whether the fan will be sufficient or if you need a more powerful one. If you’re struggling to find the extraction rate, you may need to look out for a litres per second (l/s) measurement. One l/s is around 3.6 m^3/hr. Therefore, to find the l/s from your extraction rate, divide it by 3.6."

"It’s the rate at which the extractor will draw out air."

"It means the rate of m3 of air sucked out by the fan, basically the more m3 the stronger the fan is."
