INTRODUCTION
3
The NOVA 3 Supplied Air Respirators are designed to provide
protection from airborne contaminants 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, NIOSH
or ACGIH regulations and recommendations.
The NOVA 3 is NIOSH approved (TC-19C-456 Type CE
Supplied Air Respirator) to provide respiratory protection in
general applications including abrasive blasting. The helmet
meets ANSI Z89.1 Type 1C Head Protection and the Inner Lens
meets ANSI Z87.1 for Eye Protection. The cape is designed to
NOVA 3 Respirators are NIOSH Approved for use with the
NV2016 Flow Control Valve, 4000-01 Cold Air Tube and the
4000-20 Hot Air Tube.
All RPB Safety products are covered by a manufactures warranty of 3
months. The manufacturer warranty covers defects in material, workmanship
obligation and your exclusive remedy shall be to repair, replace or refund
the purchase price of such parts or products upon the presentation of
proof of purchase.Maximum liability is in no case to exceed the value of
the RPB Safety product involved.

The NOVA 3 Supplied Air Respirator consists of 4 main
components:
Respirator Helmet Assembly
Respirator Cape
Breathing Tube Assembly
Air Supply Hose
All 4 components must be present and properly assembled
to constitute a complete NIOSH Approved Respirator.
Failure to use genuine RPB Safety NIOSH approved parts and
components voids the approval of the entire respirator assembly.

®
Inspect all components of the respirator daily for signs of
damage or wear and tear that may reduce the level of
protection originally provided.
Do not use silica sand or abrasives containing silica, lead,
arsenic or sharp glass particles - use of abrasive containing
these elements could result in serious injury or death.
Do not wear this respirator until you have passed a complete
physical exam including a lung X-ray conducted by qualified
medical personnel.
Improper use of this respirator or use not in accordance with
this User Instruction Manual may cause injury or death.
Improper use may also cause life threatening delayed lung
diseases such as silicosis, pneumoconiosis or asbestosis.
This respirator, when properly fitted and used, significantly
reduces but does not completely eliminate the breathing of
contaminates by the respirator wearer.
Be certain your employer has determined that the breathing air
source provides at least a Grade D breathable air as specified
in the compressed gas association commodity specification
G-7.1. The respirator must be supplied with clean breathable
air at all times. A carbon monoxide monitor must be used at all
times. Contact your RPB distributor for a Radex 08-200 CO
Monitor.

toxic gases, inert gases or other unbreathable non Grade D
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. Failure to connect the supply hose to
the proper air source could result in serious injury or death.
If this respirator is used in confined spaces ensure the area is
well ventilated and that all contaminate 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.
Leave work immediately if:
NOVA 3 Respirators do not provide hearing protection.
Earplugs or earmuffs must be properly fitted when exposed

AIR QUALITY
This respirator must be supplied with clean breathable air at
all times. Breathable air must at least meet the requirements
for Type 1 gaseous air described in the Compressed Gas
Association Commodity Specifications G.7.1 (Grade D or
higher) and as specified by Federal Law 42 CFR 84, subpart
J.84.141(b) and 29 CFR 1910.134 (i) the NOVA 3 does not
purify air or filter contaminants.
AIR SOURCE
Locate the air source in a clean air environment, always use a
filter on the inlet of your air source. Do not park vehicles
beside your air inlet as this 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. The air should be
regularly sampled to ensure that it meets Grade D
requirements.
BREATHING AIR SUPPLY HOSES AND FITTINGS
NIOSH approved RPB Safety air supply hoses and fittings
must be used between the point of attachment and the
The hose sections must be within the approved length and
the amount of sections must be within the number specified
in the breathing air pressure table on page 11.
OPERATION

RESPIRATOR
BREATHING AIR PRESSURE
The air pressure must be continually monitored at the point of
attachment. Air pressure must be read from a reliable
pressure gauge whilst the respirator has air flowing through it.
WARNING: Failure to supply the minimum required air
pressure at the point of attachment for the length of air supply
hose could result in contaminants being inhaled as the
pressure in the helmet may become negative due to peak
inhalation flow when working at very high work rates.
The NOVA 3 Breathing Air Pressure table on page 11 defines
the air pressure ranges needed to provide the respirator with
a volume of air which falls in the required range of 6-15cfm or
170-425 Its/min.
Make sure you understand the Breathing Air Pressure table
before using this respirator.
Determine your air source (column 1)
Identify your breathing tube assembly (column 2)
Confirm the part number of the air supply hose you are using
(column 3)
Check your RPB Safety Air Supply Hose is within the NIOSH
approved length (column 4)
Set the air pressure at the point of attachment within the
range specified (column 6) for your breathing tube assembly,
hose length and number of hose sections. (column 5)
Make sure air is flowing through your respirator when setting
the air pressure.

As the NOVA 3 Supplied Air Respirator has a limited service
life, a regular inspection and replacement programme must be
conducted. Before using the Respirator all parts should be
inspected for damage or wear and tear. Replace all worn or
damaged parts immediately. Use only NIOSH approved RPB
Safety parts. Refer to Parts and Accessories section on
pages 22-25 part numbers.

BREATHING TUBE ASSEMBLY
Inspect the Breathing Tube NV2021B for splits or excessive
wear. Check that the fittings are secured into the tube and are
not allowing any air to escape.
Replace the tube as soon as signs of damage or excessive
wear become evident. Do not remove the foam that is inside
the Breathing Tube as it reduces the noise level of the
incoming air.
