iso SF6 room Vacuum For determining the quality

In a normal home, an air-conditioner changes room air 0.5 to 2 times per hour. In a cleanroom, depending on classification and usage, air change occurs anywhere from 10 to more than 600 times an hour. ACR is a prime variable in determining ISO and Federal cleanliness standards.
