INTRODUCTION
The RPB ASTRO SUPPLIED - AIR
RESPIRATOR TYPE CE is specifically
designed for use during Abrasive Blasting.
The ASTRO has been designed for use
in atmospheres NOT IMMEDIATELY
DANGEROUS TO LIFE OR HEALTH, and from
which a user can escape without the aid
of the respirator, or that do not exceed
concentrations allowed by OSHA, EPA or
NIOSH regulations and recommendations.
The RPB ASTRO is Approved by NIOSH
(TC-19C-417, 19C-423 TYPE CE to provide
respiratory protection in abrasive blasting
and type CE painting applications. The cape
is designed to protect the wearers upper
body from rebounding abrasive.

RESPIRATOR COMPONENT CONCEPT
The RPB ASTRO SUPPLIED AIR RESPIRATOR consists of three main components:
RESPIRATOR HELMET ASSEMBLY, BREATHING TUBE ASSEMBLY, and AIR SUPPLY HOSE
illustrated in Fig1.1. All three components must be present and properly assembled to
constitute a complete NIOSH approved Respirator.

DOFFING YOUR HELMET
To remove the helmet, first exit the working area and reverse procedures in Respirator Use.
!WARNING! NEVER remove your helmet when in the working area.
INSPECTION, CLEANING AND STORAGE
The RPB ASTRO Supplied Air Respirator has a limited service life, therefore a regular inspec-
tion and replacement programme must be conducted. Certain parts such as lenses must be
replaced frequently.
All components of the respirator assembly should be inspected for damage or wear and
tear before use. Replace worn or damaged parts immediately. USE ONLY RPB SAFETY
ASTRO PARTS. Refer to the parts list for the correct part numbers.
!WARNING! DO NOT CLEAN RESPIRATOR WITH VOLATILE CHEMICALS.

AIRLINE FILTRATION
The RPB RADEX AIRLINE FILTER offers
increased capacity, versatility and filtration.
This optional equipment combines the
versatility of either floor or wall mounting
with increased filtration capacity, enabling
customization to meet workers needs and
working environments.
AIR TEMPERATURE CONTROL
The RPB 4000-01 Cool Air Tube cools
compressed breathing air coming into
the respirator by up to 30F while the
RPB 4000-20 Hot Air Tube will heat the
compressed air by up to 30F. These
maximize worker comfort and increase
productivity in hot or cold climates.
AIR QUALITY MONITORING
The RPB RADEX CO MONITOR helps
ensure worker safety with a unique
traceability feature that monitors and
records carbon monoxide levels, and
temperature. This data that provides
certainty of monitor functioning and can
be stored for up to two years allowing
analysis of plant and field air quality.
