Description
Within the Ethafilter A Series Walker range, the ETH3711HC is the Ultramax Systems replacement element. As a Grade HC hopcalite element it converts carbon monoxide to carbon dioxide across a catalytic bed. The element belongs in a breathing air train, downstream of the coalescing and carbon stages. It sits where the safety case for the whole train rests. Dimensions follow the original, so it installs into the existing housing without modification. Housings in the A30HC family take this element. Australian stock holding keeps lead times short, at a working budget price relative to the OEM part.
This replacement filter element from Ultramax is a high-quality, Ethafilter A Series-compatible alternative. Designed as an alternative to OEM part numbers E3711HC. It is engineered to suit housing models A30HC. Manufactured to strict quality standards, it delivers reliable system protection at a competitive price.
