For proper filtration, do not fill tanks rapidly as this small filter is made to handle a maximum of 6-7 CFM air flow. For the filter to work as designed, a 10+ minute fill on 80 cu ft tanks is required. An indicator strip is visible through the clear filter element. The indicator strip should be checked regularly for remaining filter life. It changes from blue to pink to white as the molecular sieve depreciates from moisture absorption.
