  • Myth vs Fact

    Myth vs Fact

    Freightliner Truck On HighwayThe Filter Minder® filter monitoring device makes it easy for you to tell when it's time to change filters.  

    The myth is that an automotive air filter should be changed about every 6,000 miles, or when it "looks dirty."

    The fact is that a certain amount of dirt in an air filter actually increases its filtering efficiency by reducing the size of the holes in the filter media which helps stop smaller dirt particles.

    This means that instead of a maximum life of 6,000 miles, the typical air filter may actually last anywhere from 60,000 to 100,000 miles!

  • When To Service?

    When To Service?

    A Dirty Filter Element Is Better Than A Clean OneAir filter restriction is not time or miles dependent.

    Mileage of as much as 300,000 to as little as 5,000 miles have been reported when restriction is reached.

    It is important to know the highest full load restriction that occurred during the vehicle operation in order to service BEFORE the redline.  

    After an element has reached its redline value, it only takes a little more contaminant before high fuel consumption and poor engine operation occurs.  Don't Dust Your Engine!

  • INTRODUCING

    The Filter Minder® Air Line Filter and Indicator

    We are pleased to introduce a new addition to its portfolio of filter monitoring products.... the innovative, versatile and convenient Air Line Filter and Indicator. Click through the showcase to learn more and view the ALFI Animation.

  • Air Line Filter and Indicator
    Early Filter Life 

    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.  

  • 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.

Filter Minder® Sensor LED Display

Filter Minder® Sensor LED Display - Round

Filter Minder® Sensor LED Display - Square

 

How It Works

The Filter Minder® Sensor LED Display is a panel or dash display capable of reading sensor output voltage to help determine filter restriction or other conditions being monitored by a sensor. As voltage increases, a light bar progressively illuminates until reaching maximum condition or full illumination of the light bar. The unit has memory and will remember the highest condition even if power is turned off. The last LED flashes when maximum condition is reached.

The display can be adjusted to Off, Dim and Bright settings. It can be reset to zero by pushing the reset button. Display will accept 6 to 30 volts input, and it can provide sensors with a regulated 5 volt signal.

Sensor LED Display - Round

 

 

The LED Display complements any voltage output sensor (0-5Vdc). It will accept 6 to 30 volts input and can provide sensors with a regulated 5 volt signal. It is capable of reading sensor output voltage to help determine the conditions being monitored. As voltage increases, a light bar progressively illuminates until reaching maximum condition or full illumination of the light bar. The unit has resident memory and will retain the highest condition, even if power is turned off. The LED in the last position flashes when the maximum condition is reached. The display can be adjusted to off, dim and bright settings. It can be reset to zero by pushing the reset button. It is available in panel or dash mounts.
