airborne contaminants, and eye/face protection; such as welding and grinding. Additionally,
the Vision-Link™light attachment is available to provide light to the work area. Quiet-Slim™
behind-the-neck style earmuffs must be worn along with the Z4®Weld Visor.
This product must be inspected and maintained in accordance with this instruction manual at
all times.
See PROTECTION PROVIDED AND LIMITATIONS (page 4) for details.

RESPIRATION
The RPB®Z4®is approved as in the categories as follows:
Powered Air
The RPB®Z4®Respirator is approved to EN 12941:1998 +A1: 2003 +A2: 2008 TH3, when
properly fitted and used with all required components, including the Breathing Tube Assembly
and the RPB®PX5®or the RPB®PX4 AIR®Powered Air Purifying Respirator. As such, it
significantly reduces, but does not completely eliminate, the breathing of contaminates by the
respirator wearer. Specific protection depends on the filter selected for use in the RPB® PX5®
or the RPB®PX4 AIR®PAPR (see PX5®or the PX4 AIR®Instruction Manual).

hours, Speed 2 - 7 hours & Speed 3 - 6 hours with the 03-985 P3 filter. The Manufacturer
Minimum Designed Flow is 180 l/min Speed 1 - greater than 4 hours, Speed 2 & Speed 3
are not recommended with the 03-995 A2P3 filter.
The Manufacturer Minimum Designed Flow for the PX5® is 170 l/min Speed 1 - 9 hours,
Speed 2 - 7 hours & Speed 3 - 6 hours with the 03-892 P3 filter. The Manufacturer
Minimum Designed Flow is 180 l/min Speed 1 - greater than 4 hours, Speed 2 & Speed 3
are not recommended with the 03-893 and 03-895 gas filter cartridge.
HAZARD LIMITATIONS

and is designed to protect the operator’s face and head against sparks and hazardous
ultraviolet and infrared rays emitted during the welding process. See “Auto-Darkening
Welding Protection Filter” (page 28) for information about ADF capabilities and use. Use an
approved RPB®welding face seal or cape for adequate protection from sparks, debris, and
light flashes.

Powered Air
Check that the contaminated area is within the limits of use for a Powered Air Purifying
Respirator and determine the type of contamination. Once the contamination level has
been confirmed you can then determine the filter cartridge to be used for the application,
to make sure that you are sufficiently protected. Make sure that the area is well ventilated
and that regular air samples are taken to confirm the atmosphere stays within the levels
recommended by local governing bodies. Follow the PX5®or the PX4 AIR®PAPR Instruction
Manual for more details.
EMPLOYER RESPONSIBILITIES
Your specific responsibilities may vary by location and industry, but in general RPB®expects that
employers will:
Follow all applicable standards and regulations for your location, industry, and activity.
Depending on your location and industry, a number of standards and regulations may
apply to your selection and use of respirators and other personal protective equipment.
These may include such things as federal, local, or military standards and regulations and
consensus standards. There are also requirements specific to particular contaminants, e.g.
silica (see rpbsafety.com for more information), asbestos, organic pathogens, etc. Know which
requirements apply to your location and industry.
Have appropriate safety programs in place.
Have and follow:
 A workplace safety program.
 A written respiratory protection program in accordance with applicable standards and
regulations.
In accordance with the above,
Perform a hazard analysis and select appropriate equipment for each activity. A
hazard analysis should be performed by a qualified person. Controls should be in
place as appropriate and a qualified person should determine what kind of respiratory,
face and eye, head, and hearing protection is appropriate for the intended activities
and environments of use. (For example, select a respirator appropriate to the specific
airborne hazards, with consideration of workplace and user factors and with an Assigned
Protection Factor (APF) that meets or exceeds the required level for employee protection,
select welding face and eye protection appropriate to the type of welding to be done, etc.)
As applicable, check your workplace safety program, respiratory protection program, and
standards and regulations for your activity or industry for related protection requirements,
and see this manual (Protection Provided and Limitations, page 4) and the PX5®or the
PX4 AIR®PAPR Instruction Manual for product specifications.

PRODUCT USER SAFETY INSTRUCTIONS
BEFORE INITIAL USE - BE TRAINED AND MEDICALLY QUALIFIED
Do not use this respirator until you have read this manual and the PX5®or the PX4 AIR®PAPR
Instruction Manual (additional copies available at www.rpbsafety.com) and been trained in
the respirator’s use, maintenance, and limitations by a qualified individual (appointed by your
employer) who is knowledgable about the RPB®Z4®Respirator.
Do not wear this respirator until you have passed a medical evaluation using a medical
questionnaire or an initial medical examination by a qualified physician or other licensed health
care professional (PLHCP).
Allergens: No known common allergens are used in this product.
Some materials could cause an allergic reaction in susceptible individuals. If you have a known
allergy or develop irritation, inform your employer. Irritation may occur from lack of cleaning.
Following all cleaning and care instructions provided in the instruction manuals for this and any
other RPB®products you are using.
MAKE SURE THE SYSTEM IS READY FOR USE
Make sure you have a complete system. Verify that you have all required components for the Z4®
to serve as a complete approved respirator:
Respirator Helmet Assembly (Z4®)
Breathing Tube Assembly
PX5®or the PX4 AIR®PAPR
See Respirator Component Diagram (page 7). The RPB®Z4®is only approved to be used with the
RPB®PX5®or the RPB®PX4 AIR®PAPR. Use only authentic RPB®brand parts and components
that are part of the approved respirator assembly. Using incomplete or inappropriate equipment,
including the use of counterfeit or non-RPB®parts, can result in inadequate protection and will
void the approval of the entire respirator. Do not modify or alter any part of this product.
Inspect all components daily for signs of damage or wear and tear that may reduce the level of
protection originally provided. Remove any damaged component or product, including any visor
that has been subject to impact, from service until repaired or replaced. Scratched or damaged
safety lenses or other components should be replaced with genuine RPB®brand replacement
parts. When safety and impact lenses are replaced, make sure to remove any additional
protective film from both sides of the lens. If the film is left in place, it could affect the optical
clarity of the lens and cause eye strain. Inspect the inside of the respirator for respirable dust or
other foreign objects. Keep the inside of the respirator clean at all times.
Make sure that the helmet is correctly assembled in the configuration that suits your application.
Never use the respirator without all lenses in place. This includes the Safety Lens, Impact Lens,
the ADF, and the rear ADF Lens. These lenses, when installed properly, are part of the respiratory
seal to prevent toxic or hazardous gases, liquids or dust from entering the helmet. An incomplete
or improperly installed lens system could provide inadequate impact and respiratory protection.
See Respirator Setup and Care (page 13). See Donning (page 30) for fit information.
