AIR SOURCE, FITTINGS, AND PRESSURE

DANGER

AIR SOURCE

Powered Air

Check that the contaminated area is within the limit s of use for a Powered Air Purifying
Respirator and determine the type of cont amination. 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 governing bodies. Follow t he PX4 AIR
details. The Manufacturer Minimum Designed Flow is 170 l/min, Speed 1 - 10 to 13 hours,
Speed 2 - 7 to 10 hours, and Speed 3 – 6 to 8 hours.

Supplied Air

Locate the air source in a clean air environment, always use a filter on the inlet of your air
source. Make sure the air sourc e is somewhere that vehicles, forklift s, and other machinery
are not running near the air inlet, as t his will cause carbon monoxide to be drawn into your
air supply. Always use suitable after coolers /dryers with filters and carbon monoxide alarms
to ensure clean breathable air is supplied at all times. A Radex
a GX4® Gas Monitor (08- 400) are recommended. The air should be regularly sampled to
ensure that it meets EN 12021 (AS/NZS 1715) requirements.

AIR QUALITY

This respirator must be supplied with clean breathable air at all times. Breathable air must at least
meet the requirements for EN 12021 ( AS/NZS 1715). The RPB
filter contaminants. A carbon monoxide monitor must be used at all times.

Do not connect the respirator’s air supply hose to nitrogen, toxic gases,

inert gases or other unbreathable non-EN 12021 (AS/NZS 1715) air
sources. Check the air source before using the respirator. This apparatus is not designed for use
with mobile air supply systems i.e. cylinders. Connecting the supply hose to a non-breathable air
source will result in serious injury or death.

INSTRUCTIONS FOR SPECIFIC USES OR ENVIRONMENTS

Welding

See Operator Setup and Use - Z-LINK+
(page 31) for important safety-related use and care information. Check the prescribed shade level
for your welding application and adjust your auto-darkening filter accordingly (see table with
recommended shade levels, page 33). Never place the auto-darkening welding filter (ADF) on hot
surfaces. Do not expose the ADF to liquids and protect it from dirt. See ADF storage, maintenance,
and cleaning information (page 32). Make sure the helmet completely blocks any accidental
light. Make sure light can only enter the front of the helmet through the viewing area of the auto­darkening welding filter.

Welding and Grinding

For welding and grinding applications that produce sparks, be sure to use the FR (Fire Retardant)
specific model of the PX4 AIR
Instruction Manual. Use a RPB® Zytec® face seal or shoulder cape for protection from sparks,
debris, and light flashes. Make sure all skin, such as the neck, is covered to prevent UV radiation
and burns.

Confined Spaces

If this respirator is used in confined spaces, ensure the area is well ventilated and that all
contaminant concentrations are below those recommended for this respirator. Follow all
procedures for confined space entry, operation, and exit as defined in applicable regulations and
standards.

Welding in Confined Spaces

Welding in a confined space can present an atmospheric hazard due to the generation of
contaminants and displacement of oxygen. A pressure-demand SCBA or a multifunctional
pressure-demand supplied-air respirator with self-contained air supply shall be used during
welding in confined spaces when welding can reduce the ambient oxygen level and supplemental
ventilation and atmospheric monitoring are not provided.

Make sure you understand the Breathing Air Pressure table before
using this respirator.

1. Use the correct air source. Do not use an ambient air pump, as it does not supply enough
pressure (column 1).

2. Confirm the part number of the air supply hose (column 2) and the flow control device
(column 3) you are using.

3. Check your RPB® Safety Air Supply Hose is within the correct length (column 4) and the
correct number of hose sections (column 5).

4. Set the air pressure at the point of attachment within the range specified (column 6).

Make sure air is flowing through your respirator when setting the air pressure.

Failure to supply the minimum required air pressure at the point of attachment for the length
of air supply hose will decrease the level of protection provided. Check that the capacity
of the air supply systems can provide sufficient air to all users, with a maximum of 5 users
connected simultaneously per air supply unit. In addition, could result in contaminants being
inhaled as the pressure in the helmet may become negative due to peak inhal ation flow when
