Air Line Filter and Indicator
End of Life

Extreme clogging will extend the red indicator (as device progresses towards full bypass mode) until it is fully extended, locked, and requires replacement. Build-up of debris will open the bypass to keep air flowing.

When restriction becomes excessive, a bright red indicator deploys from the device, indicating it is time to change the filter.

The filter cartridge is replaceable with a 1-1/4” wrench/socket and is ready again to protect your operating assets in just seconds.

Air Line Filter and Indicator

In routine use, air flows through the Air Line Filter, trapping particles.

The Air Line Filter and Indicator (ALFI) protects against harmful debris and contaminants in high pressure air lines in a wide variety of industrial, transportation and on-site applications requiring compressed air or gas.
