Caution: This unit is designed for indoor use only.
Caution: For General Ventilating Use Only. Do Not Use To Exhaust Hazardous Or Explosive Materials And
Vapors.
Warning: Do not connect the unit’s power cord to a supply receptacle unless the inlet and power modules
are in their proper position and latched together.
Warning: Abatement Technologies air filtration systems are not intrinsically safe for use in hazardous
environments. Always consult a certified industrial hygienist before using them. Do NOT use this
equipment in any atmosphere that is or may be immediately dangerous to life or health (IDLH),
combustible, flammable, explosive, oxygen deficient, and/or contains odors, vapors, gases or particulates
that exceed permissible exposure levels. Such atmospheres may require the use of intrinsically safe
equipment, specific engineering controls, and personal protective equipment in accordance with
Occupational Safety and Health Administration (OSHA), Environmental Protection Agency (EPA),
Canadian Standards Association (CSA), and other federal, state, provincial and local regulations.
Warning: This equipment is not classified as “intrinsically safe” and should not be used in the following
hazardous locations as defined by the Underwriters Laboratories: Class I Division 1, Class I Division 2,
Class I Zone 0, Class I Zone 1, Class I Zone 2, Class II Division 1, Class II Division 2, Class III Division
1, Class III Division 2. Refer to http://en.wikipedia.org/wiki/Electrical_equipment_in_hazardous_areas.
Warning: Do not use this unit near sparks, open flames or other possible sources of ignition.
GENERAL INFORMATION
The PRED1200 Portable Air Scrubbers are multi-use air filtration devices, equipped with pre-filters and a HEPA
filter that are capable of filtering many airborne contaminants. An alternate carbon pre-filter for capturing low
concentrations of odors, vapors, gases, and volatile organic compounds, collectively known as OVG, is also
available.
Types of contaminants captured by particulate pre-filters, HEPA filter, or carbon filters:
Unpleasant nuisance odors
Note: To capture low concentrations of OVG, a VAPOR-LOCK® carbon filter must be used.
The PRED1200 Portable Air Scrubbers are capable of providing particulate and odor, vapor, gas filtration with
final stage filtration through a High Efficiency Particulate Air (HEPA) filter. These units incorporate a series of
particulate filters that successively remove larger size to smaller size particles from the air. In addition to
providing HEPA filtration, the PRED1200 units are primarily used in a negative pressure or recirculation mode.
A negative pressure condition is created in order to confine contaminated airborne particles. This condition
exists when the static pressure inside the room containing the unit is lower relative to the pressure of the
environment outside the room. The static pressure differential is created and maintained by continuously
exhausting air out of a given room at a faster rate than air enters the room from all other sources. In the
recirculation mode, all of the filtered air is exhausted back into the room containing the unit.
STANDARD AIR FILTER STAGES (SUPPLIED WITH THE UNIT)
The PRED1200 units come equipped with two progressively efficient pre-filters mounted in the pre-filter
compartment, and a final stage HEPA filter, located inside the cabinet:
