  • 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® Heavy Duty Pressure Sensor

Heavy Duty Vacuum / Pressure Sensor

Continuous Monitoring | Direct Mount

1/2-18NPT

 

How It Works

The Filter Minder® Heavy Duty Pressure Sensor monitors vacuum and/or pressure on filter systems or virtually anywhere vacuum or pressure needs to be monitored. It provides a progressive output from .5 to 4.5 volts full scale. It is an absolute sensor and  measures vacuum and/or pressure from .5 to 300 psia (3.4 to 2068 kPa).

Applications include fuel pressure, oil pressure, air pressure, water pressure, gaseous pressure and others.

Heavy Duty Pressure Sensor Specifications

Filter Minder® Low Pressure Sensor

Air Filter Restriction Monitoring Sensor

Continuous Monitoring | Direct Mount

 

How It Works

The Filter Minder® Low Pressure Sensor continuously monitors vacuum in the air induction system, reporting air filter restriction.  As vacuum or air filter restriction increases, the sensor gives a comparable voltage output range of 0.5 to 4.5 volts full scale. Air filter capacity used and remaining air filter service life can be determined throughout the entire life of the filter.

HVAC version available.
