Breathing Air Filtration Upgrade

For breathing air applications, upgrade to the SC000340-MHC disposable filter cartridge that contains molecular sieve, CO catalyst, and activated carbon that removes moisture, hydrocarbon, carbon monoxide, carbon dioxide, particles, oil, and taste/odor.

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.
