PA20 Principle of Operation

• A PA20 Powered Air Purifying Respirator System
  consists of four components
• Hood
• Breathing Tube
• Blower Unit
• High Efficiency Particulate (HEPA) Filter

4
PA20 Principle of Operation

• Battery Powered Belt Mounted Blower Unit draws
  air through a HEPA filter located inside the
  Blower Housing
• Filtered Air is delivered through the breathing
  tube and into the workers hood or loose fitting
  facepiece
• A design minimum of 7.5 cubic feet per minute
  (cfm) is delivered to the hood NIOSH requires
  only 6 cfm

5
Proper Use Warnings

• Follow OSHA-defined respirator selection criteria
  when selecting proper respiratory protection.
• Know the work environment and the potential
  hazards that could exist.
• Do not use in atmospheres considered immediately
  dangerous to life or health (IDLH), or that are
  above the Maximum Use Concentration (MUC).
• Leave area immediately if Breathing
  becomes difficult Dizziness or other distress
  occurs You taste or smell the contaminant
  Unit becomes damaged Battery alarm sounds
• This apparatus must not be worn with the blower
  unit switched off. If the blower is switched off,
  a rapid build-up of carbon dioxide and depletion
  of oxygen may occur, which could result in death
  or serious injury.
• Never alter or modify this respirator. Use only
  NIOSH approved PA20 components and replacement
  parts for this respirator.
• Do not use in atmospheres containing less than
  19.5 oxygen.

Assembly

• Attach Breathing Tube to Blower Unit, insuring
  gray seal is in place (below)
• Make sure that filter assembly is installed into
  blower unit housing
• Attach the other end of the breathing tube to the
  hood by inserting the tube into the sleeve on the
  hood approximately 5 and securing with the
  anchor plate and clamp (right)
• Secure suspension into hood by snapping into
  place
• Remove tissue from hood lens

7
Pre-Operational Inspection

• Ensure that the Blower Unit and Hood are clean
  and free from damage
• Insure that all needed NIOSH-approved components
  are present for operation
• Inspect for Deterioration, Physical Damage, and
  Improper Assembly
• Ensure that NIOSH-approved Bullard filter is in
  place inside the Blower Assembly
• Check for proper airflow using the air flow
  indicator

8
Donning / Doffing

• Donning / doffing should take place in a clean,
  hazard-free environment
• Place the blower unit and belt around the users
  waist and adjust the belt for a proper fit
• Follow proper assembly and pre-operational
  instructions
• Turn on the blower unit
• Place the hood on the head and adjust the
  suspension for a comfortable and secure fit

9
Low Voltage Audible Alarm

• The alarm may indicate
• Low Battery Voltage
• Clogged or Damaged Filter
• Blower Malfunction
• Breathing Tube or Hood Malfunction
• (see Instruction Manual for Troubleshooting)
• If the alarm sounds, exit the work area and place
  the blower unit on charge

10
Charging the Internal Batteries

• Remove the charging port cap by turning counter
  clockwise and pulling
• Connect the lead from the batter charger to the
  port on the blower unit by aligning the pins,

• Observe additional battery charging and care
  precautions in the User Manual
• After periods of extended storage or non-use,
  please refer to the User Manual for special
  charging procedure

11
PA1FG HEPA Filters

• PA20 Series HEPA filters protect against
  particulates, and are at least 99.97 efficient
  against 0.3 micrometer diameter mono-disperse
  particles
• Never attempt to clean these filters!!
• Banging or blowing the filter may cause damage to
  the filter
• Use only Bullard replacement filters - NIOSH
  requirement

• Replace filter when airflow is below the PASS
  line on the airflow indicator, if the filter
