Hankison Catalite Breathing Air Systems

• Compressed air contaminants contribute to respiratory ailments and excessive absenteeism.
• Low concentrations of carbon monoxide detrimentally affect bodily coordination, reaction time, and visual acuity causing accidents; higher concentrations can lead to permanent impairment or death.
• The oily odor in compressed air causes nausea and breathing discomfort.
• Filter panels and powered air respirators do not remove carbon monoxide (CO). If CO is detected, production must stop or expensive bottled air used.
• Water, oil, and solid particles, if not removed, can damage critical components, cause regulators to clog and in outdoor applications cause airlines to freeze.

Meets OSHA and CSA Standards for Breathing Quality Air

Operation

1. A Hankison one micron coalescing filter removes gross solid and liquid contaminants.
2. A Hankison 0.01 micron ultra high efficiency coalescing type oil removal filter removes virtually all liquid oil aerosols (mist).
3. A Hankison pressure-swing regenerative desiccant dryer dependably reduces the moisture content to a level that ensures the effectiveness of the catalyst bed.
4. A catalyst bed lowers carbon monoxide (CO) concentrations by converting CO to CO₂.
5. A Hankison activated carbon filter removes oil vapor (and other gases normally adsorbable by activated carbon) and the undesirable odor it imparts to the air. A final layer of media prevents solid particles 0.01 microns and larger from passing downstream.

Highly Visible Warning of Unsafe Operating Conditions

Ease of Installation and Operation

Long Service Life - Low Operating Costs

• Optimally sized towers contain sufficient desiccant to ensure adequate moisture removal while saving the heat of adsorption to minimize purge air usage
• Slow and complete tower pressurization plus reduced air velocities prevent bed movement, preserving desiccant life
• Solid state controller and reliable air control valves ensure dependable operation
• Purge valves are normally closed, protecting the unit from outside contamination when the unit is shutdown
• Inlet valves are normally open - allows flow to continue if a power interruption occurs
• Purge exhaust mufflers for quiet operation
• ASME code constructed pressure vessels; desiccant towers include relief valves

Instruments and Controls

• Inlet and outlet air pressure gauges
• Left and right tower pressure gauges
• Purge flow indicator
• Moisture color change indicator -- gives advance warning of need for purifier maintenance
• Prefilters equipped with differential pressure gauges -- indicate the need for element replacement

Control panel is supplied with:
• On/off switch
• Tower status lights
• Switching failure alarm
• All instruments and controls are front mounted for easy visibility and use

Flow Capacity

1. Rated capacity- Rated capacities shown in Table 1 are established at inlet conditions of 100 psig (7 kgf/cm²) and 80°F (27°C). At rated flow, inlet concentrations of 200 ppmv/v are reduced to 20 ppmv/v, 135 ppmv/v to 10 ppmv/v, 100 ppmv/v to 5 ppmv/v.
2. To determine inlet capacities at other conditions: Step 1: Inlet temperature and pressure adjustment: Multiply inlet flow from Table 1 by the factor from Table 2 that matches your operating conditions. Example: model 1912 has a capacity of 54.6 scfm at 120 psig and 100°F (47.9 scfm x 1.14 = 54.6 scfm). Step 2: Inlet/Outlet CO concentration adjustment: multiply flow from Step 1 by the factor from Table 3 for the maximum CO concentration expected at the purifier inlet and the desired CO concentration at the purifier outlet. Example: With a maximum CO concentration of 135 ppmv/v at the inlet and a desired concentration at the outlet of 5 ppmv/v, the adjusted flow from Step 1 becomes 50.2 scfm (54.6 scfm x 0.92= 50.2 scfm).
3. To determine outlet flow: subtract purge flow from Table 1 for the model under consideration from the corrected inlet flow. Example: 50.2 – 7.9 = 42.3 scfm available at the outlet.

OSHA and CSA Standards

1. The OSHA standard also states that compressed breathing air shall meet at least the requirements for Type 1-Grade D breathing air described in ANSI/Compressed Gas Association Commodity Specification for Air ANSI/CGA G-7.1-1989.
2. The CSA standard lists levels for a number of additional contaminants (methane, nonmethane hydrocarbons, nitrogen dioxide, nitrous oxide, halogenated hydrocarbons) and includes by reference contaminants documented by the ACGIH for chemical substances and physical agents in the workroom environment. The purifier will remove only those gaseous contaminants normally adsorbable by activated carbon.
3. CO is converted to CO₂ by the purifier. Although some CO₂ is adsorbed in the desiccant beds, high concentrations of CO₂ at the compressor intake, in addition to the CO₂ produced in the purifier could result in exceeding CO₂ limits.
4. The purifier will remove only those gaseous contaminants normally adsorbable by activated carbon.
