Warning Indicators for Filters
Colorator, Colorgage and Marvindicator are element condition indicators for sump and suction filters that
warn of dangerous element clogging allowing element cleaning or replacement before damage occurs.
Electrical connections for audio signals and/or warning lights also provided. However, many users find the
attention-compelling Red Pop-Up Button a sufficient warning signal as well as the Red, Yellow and Green of
the Colorator and Colorgage.
