By using the Modular Stackable Ring, you are able to attach GUARDIAN breather cartridges to extend the service life. This stackable ring also allows for the addition of the High-Capacity Air Filter and Activated Carbon FIlter.
Stack cartridges of silica gel, activated carbon or molecular sieve
Protect equipment from caustic fumes, extend the performance range or increase the life of a desiccant breather.
Connecting two cartridges of similar size can reduce air flow by up to 50%.
Note:
When using the Modular Stack Ring™, do not stack multiple cartridges with Isolation Check Valves. Use the Isolation Check Valve on the bottom cartridge only.
