Description
2.1
Product overview
The Dräger PAS Filter Series is a range of wall-mounted and portable air
filter units that provide high-quality breathing air by filtering the air output
from a compressed air source, such as a factory airline or mobile
compressor. A portable unit has a carrying handle and stand as shown in
the lower image in Fig 1.
The filter unit is contained within a cabinet manufactured from impact-
resistant polyethylene. There are labels on the inside of the cabinet that
provide pressure and flow requirements, a maintenance schedule, and a
list of replacement parts.
The filtration system removes liquid and solid particles down to 0.01
μ
m and
oil vapour and odours down to 3
μ
g/l. All models have coalescing (Fig 1,
Item 1) and activated-carbon (2) filters, with duplex filter elements.
Additionally, F3500 and F5500 models are fitted with a pre-filter (3) to
remove coarse contaminants from the air supply. The filtration system also
has an automatic drain that collects condensate from the filters in a bottle (4).
The unit has an adjustable pressure regulator (5) and an output pressure
gauge (6). The pressure regulator is used to adjust the cabinet output to the
required pressure, and a 6 mm hexagon key is supplied with the product for
this task. The pressure range on the gauge is suitable for positive-pressure
and constant-flow systems in accordance with the requirements of EN 14593
and EN 14594.
The unit is fitted with a BSP inlet coupling and CEJN compatible outlet
quick couplings. The inlet coupling (7) is on the left-hand side of the
cabinet. The outlet couplings (8) are on either the bottom (wall-mounted
units) or the right-hand side (portable units) of the cabinet. Models are
available with 3 outlets (F3000/F3500) and 5 outlets (F5000/F5500).
Model numbers with a suffix of P (e.g. F3500 P) indicate that the unit is a
portable version.
2.2
Intended use
The Dräger PAS Filter units filter the air from a compatible compressed air
supply (see Section 3.1) to provide breathing-quality air by removing liquid
and solid particles.
2.3
Limitations on use
Dräger PAS Filter units do not include filters or purifiers for removal of carbon
monoxide, carbon dioxide or other toxic gases and fumes.

Use
3.1
Compressed air supply
Ensure that the compressed air supply is from a factory airline or mobile
compressor as detailed in this section. If in doubt about the quantity or
reliability of the air supply, contact Dräger for supply of a suitable
compressor.
!
WARNING
!
Using an air supply that contains toxic gases or does not comply
with temperature, pressure and flow requirements could result in
death or serious injury for the user.
Wearers of breathing apparatus being supplied by the filter unit
must have a reserve supply of air to allow them sufficient time to
evacuate to a safe area in the event of a compressor failure.
The filter unit does not remove carbon monoxide, carbon dioxide
or other toxic gases and fumes.

The filter unit should be used in a safe and uncontaminated area,
and should be securely held or placed in a position where it can
not be damaged.
Ensure that the compressor intake is not near any polluted or toxic
atmosphere, and works preperly.
The compressed air supply must not exceed a temperature of 45 °C and
must not be more than 5 °C above the ambient temperature. This is to
prevent the build up of condensation in the breathing air. The compressed
air source should include an after-cooler.
!
3.1.1
Inlet pressure
●
Compressor with an air dryer – The inlet pressure to the unit must be
at least 0.5 bar above the pressure required at the unit outlet, and
below the maximum inlet pressure of 16 bar.
●
Compressor without an air dryer – The inlet pressure must be at least
5 bar above the pressure required at the unit outlet, and below the
maximum pressure of 16 bar, to ensure a pressure dew point of 5 °C
below ambient temperature.
3.2
Mounting the wall-mounted unit
CAUTION
Observe normal precautions when drilling into walls or other
structures to avoid damage to existing wiring, gas pipes, water
pipes, etc.
1. Open the cabinet and hold the cabinet against the wall in the desired
location. Ensure that there is sufficient space around the cabinet to allow
coupling connection, and to allow the cabinet cover to be fully opened.
2. Mark the mounting screw positions using the cabinet as a template.
3. Drill the mounting holes. Dräger recommend a drill bit size of
approximately 5 mm (number 8).
4. Fix the earth strip under one of the screws and mount the cabinet
securely using appropriate wall plugs and screws.
3.3
During use
Ensure that the cabinet is clean and undamaged, paying particular
attention to pneumatic components, hoses and connections. Typical signs
of damage that may affect the operation of the product include impact
damage, abrasion, cutting, corrosion and discoloration. Report damage to
service personnel or Dräger and do not use the cabinet until faults are
rectified.
!
1. If using a portable unit, stand the cabinet upright.
2. Empty the condensate collection bottle.
CAUTION
!
The contents of the condensate bottle may be contaminated with
oil and pose an environmental hazard. Handle and dispose of the
contents in accordance with national or local regulations.
3. Connect the compressed air supply to the inlet coupling of the filter
unit.
4. Check the outlet (working) pressure shown on the output pressure
gauge:
a. For continuous flow breathing apparatus, it must be within the
green area on the gauge.
b. For positive-pressure breathing apparatus, the pressure must be
within the range shown in the tables below.
5. If required, adjust the pressure regulator as follows:
a. Open the cabinet.
b. Release the wing nut (Fig 2, Item 1).
c. Turn the control bolt (2) to set the required pressure on the gauge.
d. Tighten the wing nut to lock the control bolt.
6. Connect the breathing apparatus to the outlet couplings.
WARNING
The airline connected to the outlet coupling must not be made up
of more than 5 individual hoses and its total length must not
exceed 100 m.
Airline equipment must allow the input pressure and flow specified
in the breathing apparatus Instructions for Use to be met. Incorrect
airline equipment configurations may result in insufficient air flow
to breathing apparatus wearers or increase the possibility of air
supply failure. Do not use the filter unit to supply air to more than
the users stated in the tables below at any time.
