Operation instruction
SR 507
Compressed air attachment
Revision: 03
General information
Instructions for use for SR 507 should be read before use.
The SR 507 is an attachment that enables a given head-top to be converted between a fan-assisted
respiratory protective device and a protective device with compressed air supply.
The Sundström SR 507 compressed air attachment can be used together with Sundström human interfaces
below named head-tops:
Hood SR 520, SR 530, SR 561, SR 562, Face shield SR 540, SR 540 EX, SR 570, helmet with visor SR 580,
half mask SR 900/SR 951.
This combination forms a breathing apparatus with continuous airflow for connection to a compressed air
supply according to EN 14594 class 3A/3B.
Use of a respirator must be part of a respiratory protection program.
For advice see EN 529:2005 or AS/NZS 1715:2009. The guidance contained in these standards highlights
important aspects of a respiratory protective device program but does not replace national or local regulations.

Breathable air
Breathable air shall meet at least the following purity requirements:
• The pollutants must be maintained at a minimum and must never exceed the hygienic limit value.
• The content of mineral oil shall be so low that the air will have no oil smell (the threshold of smell is around
0.3 mg/m³).
• The air shall have a sufficiently low dew point to ensure that no internal freezing will take place in the
equipment.
In the event of uncertainty as to whether the above demands have been met, a filter such as the Sundström
type SR 99-1 compressed air filter should be connected.

1. Functional check before use
2020-03-20
OI03H-0618 SR 507 5
On every occasion before using the equipment:
• Check on the rated capacity of the compressed air system.
• Check the maximum number of users permitted.
• Check the number of users already connected.
Check that the minimum flow of air through the head top is about
175 l/min
1.1 Connect the adapter to
the breathing hose of the
head top.
1.2 Connect the breathing
hose to the control valve.
1.3 Connect the compressed
air hose to the control valve.
1. Functional check before use

1.4 Turn the control valve
knob anticlockwise as far as it
will go in order to throttle the
airflow rate to a minimum.
1.5 Turn the flow meter bag
inside out and the flow meter
appears.
Hint: Turn the bag inside out
and use it for storing the
equipment
1.6 Place the head-top in the
flow meter. Grip the bag to
seal around the breathing
hose. Grip the flow meter
tube with the other hand, the
tube will point upwards from
the bag
Read the position of the ball
in the tube. This should hover
at a level with or slightly
above the upper marking on
the tube, (175 l/min).
If minimum flow is not
achieved, check that
-the flow meter is held
upright,
- the ball moves freely,
- the bag seals well around
the hose.
2. Putting the equipment on
2020-03-20

2.1 Put the belt on and adjust
the belt length.
2.2 Arrange the control valve
in a way that allows easy
adjustment of the flow rate
and a strict watch over the
breathing hose, i.e. it must
not be placed on the back of
the waist.
2.3 Then fit the connection
adapter to the breathing hose
of the head.
2.4 Connect the breathing
hose to the control valve
outlet.
2. Putting the equipment on

2.5 Connect the hose to the
control valve inlet.
2.6 The head top is now
being supplied with air and
you can put it on.Adjust the
head harness.
2.7 Use the control valve
knob to set the air flow rate to
suit your current work
intensity. In the fully closed
position (turn the knob anti-
clockwise), the flow is about
175 l/min, and in the fully
open position (turn the knob
clockwise), it is about 260
l/min.

4. Cleaning
2020-03-20
OI03H-0618 SR 507 10
The silencer of the compressed air accessory, i.e. the part inserted
into the hose, is sensitive to water. So clean the equipment before
dismantling it.
If necessary, spray the product with 70 % ethanol or isopropanol
solution for disinfection.
N.B. Never use a solvent for cleaning.
4.1 Sundström cleaning
tissue SR 5226 that clean
and disinfect are
recommended for daily care.
4.2 If the equipment is more
heavily fouled, use a soft
brush or sponge moistened
with a solution of water and
dishwashing detergent or the
like. Rinse the equipment and
leave it to dry
