My next installment will cover Zero Air Generators.  There are several models Restek sells, which vary by output flow rates and purity.  Each of these models will be discussed below.  They will include Parker 75-83NA, HPZA-3500, HPZA-7000, HPZA-18000, HPZA-30000.   The most noticeable difference between these models is capacity.<\/p>\n\n\n

75-83NA<\/strong><\/h2>\n\n\n\n

The Restek part number for this generator is\u00a020684<\/strong>. \u00a0This model is capable of 1000 cc\/min. \u00a0The preferred installation is for this unit to be wall mounted, although it can be installed onto a benchtop. \u00a0The Parker Installation, Operation and Maintenance manual can be found here \u00a0TI-7583H.pdf<\/a>\u00a0 The 75-83NA model takes compressed air and purifies it into zero grade air using a combination of filters and a catalyst. The prefilter removes oil mist, particulates, and moisture from the incoming compressed air supply. \u00a0The catalyst oxidizes any remaining hydrocarbons from the compressed air supply into carbon dioxide and water. \u00a0A second, final filter removes additional particulates.<\/p>\n\n\n\n

Maintenance requirements for these generators include an\u00a0annual\u00a0maintenance kit, Restek\u00a021646<\/strong>\u00a0(Parker MK7583) and a catalyst tower, Restek\u00a022005<\/strong>\u00a0(Parker 75394, which needs to be replaced every\u00a0two years).<\/p>\n\n\n\n

Included in maintenance kit 21646:<\/p>\n\n\n\n

    \n
  1. Prefilter (Parker 050-05-BX)<\/li>\n\n\n\n
  2. Final filter (Parker A01-0185)<\/li>\n<\/ol>\n\n\n\n

    A couple of specifications to keep in mind: for every generator model listed in this post, the minimum\/maximum incoming (compressed) air temperature is 60 \u00b0F\/100 \u00b0F<\/strong> and the minimum\/maximum incoming (compressed) air pressure is 40 psi\/125 psi<\/strong>.<\/p>\n\n\n\n

    HPZA-3500<\/strong><\/h2>\n\n\n\n

    The Restek part number is\u00a029282<\/strong>. \u00a0This model has a maximum flow rate of 3500 cc\/min. This unit is larger\/heavier than the 75-83NA model, so the preferred installation is bench top, but it can be mounted on the wall. The Parker Installation, Operation and Maintenance manual can be found here TI-HPZA-3500H.pdf<\/a>\u00a0<\/p>\n\n\n\n

    In this model, compressed air is forced through two prefilters, followed by a catalyst tower, and finally through a final filter. \u00a0The\u00a0annual\u00a0maintenance kits, Restek\u00a021647<\/strong>\u00a0(Parker MK7840)\u00a0and 29286 (MKZAG-12M), include the following:<\/p>\n\n\n\n

      \n
    1. First stage prefilter (Parker 100-12-DX)<\/li>\n\n\n\n
    2. Second stage prefilter (Parker 100-12-BX)<\/li>\n\n\n\n
    3. Final filter (Parker GS-050-05-95)<\/li>\n<\/ol>\n\n\n\n

      A catalyst tower, Restek\u00a022004<\/strong>\u00a0(Parker 76810), is also available. \u00a0Unlike the replacement schedule for the 75-83NA model, the catalyst tower should be replaced when the following occurs (according to page 7 of the manual):<\/p>\n\n\n\n

      The catalyst module in the Parker Balston Zero Air Generator should be changed when the \u201cCheck System\u201d LED is illuminated or blinking to maintain the hydrocarbon removal specification for the unit.<\/em><\/p>\n\n\n

      \n
      \"\"<\/figure>\n<\/div>\n\n\n

      HPZA-7000<\/strong><\/h2>\n\n\n\n

      The Restek part number for Parker model HPZA-7000 is 29283<\/strong>. \u00a0As you may have guessed, the maximum flow rate is 7000 cc\/min. \u00a0The manual is the same as for HPZA-3500, TI-HPZA-3500H.pdf<\/a>, and so are the maintenance kits (Restek\u00a021647<\/strong>, Parker MK7840; and Restek 29286, Parker MKZAG-12M), but the catalyst tower is different (Restek\u00a022006<\/strong>, Parker 76820). \u00a0Preferred installation is on a bench top. \u00a0<\/p>\n\n\n\n

      HPZA-18000<\/strong><\/h2>\n\n\n\n

      The Restek part number for this generator is\u00a029284<\/strong>. \u00a0The maximum flow rate is 18,000 cc\/min. \u00a0Once again, the maintenance kit is the same (Restek\u00a021647<\/strong>, Parker MK7840) but the catalyst tower is different\u00a022007<\/strong>\u00a0(Parker 76811).<\/p>\n\n\n\n

      HPZA-30000<\/strong><\/h2>\n\n\n\n

      The highest capacity zero air generator Restek sells is Parker\u2019s HPZA-30000 model, Restek\u00a029285<\/strong>. \u00a0This unit has a maximum flow rate of 30,000 cc\/min. \u00a0As you may expect, the maintenance kits are the same (Restek\u00a021647<\/strong>, Parker MK7840; and Restek 29286, Parker MKZAG-12M) but the catalyst tower is different\u00a022008<\/strong>\u00a0(Parker 76821).<\/p>\n\n\n\n

      As you can see, generator selection is straightforward; simply select the zero-air generator that matches your flow needs.  Then, instead of the drudgery of changing zero-grade air cylinders, use a zero-air gas generator instead.   Thanks for reading.<\/p>\n\n\n\n
