ZEKS Compressed Air-Line Filters

ZFF™ Flanged Filters remove harmful moisture and contaminants in large scale compressed air systems to protect production processes and tools and guard against process failure and product spoilage.
Multi-element design and simple flow path result in efficient, high volume filtration with low pressure drop. Replaceable filter elements are available in five grades allowing users to meet their unique filtration requirements.

If at any time a different air quality is needed, simply select one of the other filter element grades.

To provide long service life without failure, ZFF™ elements are constructed to include:

• Stainless Steel Support Core – will  withstand high differential pressures
• Deep-Pleated Filter Media – maximizes filtration efficiency in each element grade
• Specialized Drainage Layer – optimized liquid drainage properties

ZFF™ filter housings meet ASME Section VIII, Division 1 requirements. The top-load design enables filter element replacement without removal of the bottom of the housing. This feature facilitates changing of the elements and minimizes the clearance requirement below the housing.

Filter maintenance is enhanced through monitoring of pressure drop as indicated on a differential pressure gauge that includes both color and numeric scales.

ZFF filters are available in four distinct element designs to remove particulate, oil vapor and oil / water aerosols from the compressed air stream.

ZFF Series Filters feature ASME-rated housings with top-loading element access for simplified element replacement. Deep-pleated filter media reduces air flow velocity to maximize filter efficiency while minimizing pressure drop.

ZFF™ filter elements are available in five grades making it possible to configure ZFF™ Flanged Filters for nearly all compressed air
applications. Elements provide long service life with high efficiency and are chosen based on specific application requirements:

• GRADE P – Particulate/Bulk Liquid Filtration
  • Air Purity: 5 microns; 5 ppm oil carryover; .5 psi Dp clean & dry; 1 psi Dp saturated; 6 psi Dp recommended replacement
    For removal of small particles and dirt, and for liquid coalescing. Also used where high concentrations
    of airborne dirt are present in the ambient air.
• GRADE G – General Purpose Filtration
  • Air Purity: 1 micron; .1 ppm oil carryover; 1 psi Dp clean & dry; 2 psi Dp saturated; 6 psi Dp recommended replacement
    Coalescing/particulate filter used to protect pneumatic tools and actuators from dirt, oil, and dust.
    Element of choice for heatless desiccant dryer afterfilter.
• GRADE H – High Efficiency Filtration
  • Air Purity: .01 micron; .01 ppm oil carryover; 1.5 psi Dp clean & dry; 3 psi Dp saturated; 6 psi Dp recommended replacement
    Used for fine coalescing and when removal of very small particles is required.
• GRADE A – Activated Carbon Finishing
  • Air Purity: .01 micron; .003 ppm oil carryover; 1 psi Dp clean & dry; NA psi Dp saturated; NA psi Dp recommended replacement
    For removal of vapors and odors. NOTE: A .01 micron, high efficiency (Grade H) filter must be installed upstream of the Grade A filter.
    Grade A elements must be replaced at 6 months or 4,000 hours, whichever occurs first.
• HI-TEMP – High Temperature Filtration
  • Air Purity: 1 micron; .1 ppm oil carryover; 1 psi Dp clean & dry; 2 psi Dp saturated; 6 psi Dp recommended replacement
    For general purpose coalescing/particulate filtration where compressed air temperature exceeds 250oF.
    Used for heated desiccant dryer afterfilter.

ZFF Flanged Filter Features:

• Flanged Connection
• Versatility – Four element grades to meet your compressed air quality requirements
• Robust Design – Housing and filter elements designed for challenging industrial applications
• Low Pressure Drop – Allows compressors to run more efficiently, resulting in energy savings
• Top-load Element Access – Permits access to elements without the need to drop the filter bowl or disconnect filter from air system

ZFC™ Filters reduce contamination in compressed air to
protect critical processes and pneumatic equipment.

ZFC™ Compressed Air Filters include features that address air quality,
enhance the operating efficiency of compressed air systems and minimize
cost-of-ownership.

ZFC filters are available in four distinct element designs to remove particulate, oil vapor and oil / water aerosols from the compressed air stream.

ZFC Series Filters feature die-cast aluminum housings that are treated with a proprietary coating for protection against corrosion in harsh environments. Deep-pleated filter media reduces air flow velocity to maximize filtration efficiency while minimizing pressure drop.

Features:

• Threaded Connection
• Versatility – Choose from four filter element grades to meet the unique challenges of each application. Elements have been developed for specific removal of bulk liquid, aerosols, course and fine dust particles, as well as for carbon finishing.
• Robust Design – Housing and filter elements designed for challenging industrial applications
• Low Pressure Drop – High pressure drop causes air compressors to work harder, adding more to compressed air system operating cost.
  ZFC™ filter housings and deep-pleated elements are designed to minimize turbulence, resulting in very high efficiency filtration with
  minimal pressure drop.
• No-Touch Element Replacement – The filter bowl is designed to properly align the element with the filter head during changeout. With ZFC™ filters, it’s not necessary to handle spent elements resulting in cleaner and faster filter maintenance. The vertical space required when separating the head and bowl during element changeout is minimal, enabling ZFC™ filters to be installed where others won’t fit.
• Long Element Life – The superior construction of ZFC™ filter elements enables them to consistently deliver clean, high quality air while maintaining integrity throughout the life of the element.

ZFC™ Element Grade Selection and Filter Application

Each filter includes one of four element grades:

• Grade P – Particulate / Bulk Liquid Filtration
  • Use for removal of dust particles down to 1 micron and coalescing of liquid; .6 psi ∆p dry.
• Grade G – General Purpose Filtration
  • Use for removal of dust particles down to 0.1 micron and coalescing of water and oil for a maximum remaining aerosol content of 0.03 ppm @ 70oF; .6 psi ∆p dry; 1.2 psi ∆p saturated.
• Grade H – High-Efficiency Filtration
  • Use for removal of particles down to .01 micron and coalescing of water and oil for a maximum remaining aerosol content of 0.008 ppm @ 70oF; .8 psi ∆p dry; 1.5 psi ∆p saturated.
    It’s recommended that Grade H filtration be preceded with Grade G filtration.
• Grade A – Activate Carbon Finishing
  • Use for oil vapor and hydrocarbon odor removal. Results in a maximum remaining oil content of 0.003 ppm @ 70oF; 1 psi ∆p initial; 1 psi ∆p final. Must be preceded with Grade H filtration.
  • Grade A Elements must be replaced every 3 months or every 2,000 hours, whichever is first. As a convenience, a Time Strip that can be adhered to the filter housing comes with Grade A elements, providing visual indication of the remaining service life of the element.
