  • CLARCOR Industrial Air Confidential Page 12 September 9, 2016

    Benefits:

    Extended filter life = Lower Cost of Ownership

    Lower labor costs Fewer filter changes required Less handling required by shipping/receiving Reduce the need for on site storage

    Lower disposal costs No need for frequent filter cleaning/recycling

    The amount of particulate by weight in a given volume of air, usually specified in grains/cubic foot (or grams/cubic meter)

    Grain Loading

    1 lb (0.454 kg) = 7000 grains

    1 kg = 15,432 grains

    Air-to-cloth ratio = ACFM total filter area

    Total # filters x sq/ft per filter = total filter area

    Magnehelic* Gauge

    *Trademarks are property of their respective owners

  • CLARCOR Industrial Air Confidential Page 19 September 9, 2016

    Pressure difference between two points in a dust collection system

    Typically measure across a tube-sheet in inches of water column

    Instruments used to measure DP are:

    U-tube manometers Magnehelic* Gauges Photohelic* Gauges Pressure Transducers

    *Trademarks are property of their respective owners

    Differential Pressure

  • CLARCOR Industrial Air Confidential Page 20 September 9, 2016

    A unit of pressure equal to the pressure exerted by a column of liquid water one inch high at standard conditions (70 degrees at sea level)

    Usually expressed as inches in water gauge (w.g) or water column (w.c)

    Fine Particle Emissions Particulate bleed through of conventional felts Aggressive design high filtration velocities High Differential Pressure Loss of Airflow High air-to-cloth ratios Poor cleaning mechanism efficiency Extra drag across filter due to primary dust cake.

    Common Problems in Pulse Jets:

  • CLARCOR Industrial Air Confidential Page 22 September 9, 2016

    Abrasion Failure Filters located in direct line of inlet gas stream Difficult Installation Bottom Load Extra downtime to handle multiple and bulky components Accurate installation of multiple filter components Aggressive Cleaning Cycles Accelerated pulse cleaning causes premature flex failure

    Common Problems in Pulse Jets:

  • CLARCOR Industrial Air Confidential Page 23 September 9, 2016

    High DP/Loss of Airflow
