General Description
The Parker HPZA Series Zero Air Generators (Figure 1) are completely engineered systems
which replace the use of inconvenient high pressure gas cylinders as a source of
hydrocarbon-free air. The HPZA-30000 generators purify on-site compressed air to a total
hydrocarbon level of less than 0.1 ppm (measured as methane). The HPZA-3500, HPZA-
7000, and HPZA-18000 generators purify on-site compressed air to a total hydrocarbon
level less than or equal to 0.05 ppm, when operated at or below the unit's maximum flow
rate. Zero-grade air from a Parker Zero Air Generator may be used as a source of fuel air for
Flame Ionization Detectors (FIDs) or as a zero reference for any instrument which measures
hydrocarbon concentration.
The Parker Zero Air Generators have been certified to the electrical safety requirements as
specified by the IEC, CSA, and UL standards. These units bear the Intertek (ETL) marking
on the product label and comply to US and Canadian Standards. Product supplied to carry
the CE mark (220/230/240 VAC units only) and comply to EMC standards. This unit has a
pollution grade of 2 to the intended environment.
Engineered System
The Parker Zero Air Generator is comprised of four functional component groups:
prefiltration, hydrocarbon removal, cooling, and final filtration (see Figure 2).

  • Page 3: Installation

    Approximately 6” of space should be allowed along the top and sides of the generator to ensure proper ventilation. Compressed Air - The Parker Zero Air Generator requires a source of clean, dry compressed air (40 psig- Utilities 125 psig/2.8 barg-8.6 barg) for optimal operation.
  • Page 4 Models HPZA-3500, HPZA-7000, HPZA-18000, HPZA-30000 Power - The Parker Zero Air Generator may be operated by a 120 VAC, 220 VAC, 230 VAC, or 240 VAC, 50/60 Hz power supply. Main supply voltage fluctuations must be within ±10% of the nominal main supply voltage.
