Introduction
For many decades WEINMANN has developed,
produced and marketed appliances for oxygen
therapy, inhalation therapy and emergency
medicine.
In 1957 WEINMANN put the first diaphragm
pressure reducer on the market.
Pressure reducers are used in medical oxygen
inhalation. They reduce the pressure delivered by
oxygen bottles from 200 bar to the specified
operating pressure.
The flowmeter is used during the inhalation of medical oxygen via the central gas supply system of a
hospital, for example.
Pressure reducers are a functional component of a
wide range of appliance combinations such as
stationary oxygen appliances and portable oxygen devices. They are therefore an important
component in the treatment of chronic respiratory
diseases and/or disorders of the cardiovascular
system.
The aim of these Service and Repair Instructions is to
familiarize you, a
the function, technology, servicing and repair of
pressure reducers and flowmeters. In conjunction
with a training course that you have already been
trained and competent expert,
with
given by WEINMANN, you now belong to that
group of “trained and competent experts”, which
means you can give your customers proper instruction, rectify faults yourself and perform the prescribed functional check and any repairs in
accordance with these Service and Repair Instructions.
In the event of any warranty claim the device must be
sent to WEINMANN
So that we can process any warranty claims or
requests for favorable treatment, please send us
the customer’s purchase slip (invoice) with the
appliance.
Repairs and/or repair work may only be performed by WEINMANN or by trained and competent experts.
You are responsible for any repairs you carry out
yourself and the relevant guarantees!

1.1 Explanation of Numbers
Type: 30800
The type row indicates the basic design of the
pressure reducer, e.g. “30800” for indexed
pressure reducers (Fast I).
Order number:
In the order number the first three numbers are a
short indication of the type, and the last two digits
indicate the specific version (e.g. the connection
variants).
Appliance number:
The first two digits of the appliance number show
the year of manufacture. The next five digits are the
consecutive appliance serial number within each
type. The appliance number is stamped on the
back of the pressure reducer.
1.2 Information about conformity with standards
Up to serial number 0849999, OXYWAY
pressure reducers meet standard EN 738-1.
From serial number 0850000, OXYWAY
pressure reducers meet standard EN ISO 105241:2006.
In the course of adapting the products to standard
EN ISO 10524-1:2006, it was not possible to
design all components to be downward-compatible. Parts which are not downward-compatible are
available for both device statuses separately and
are marked accordingly in the replacement parts
lists (see “8. Replacement Parts” on page 64) of
these instructions.
• Fit replacement parts which are not downward-compatible only
pressure reducer serial numbers quoted.
• Do not convert pressure reducers up to
SN 0849999 “to suit the new standard”.
in accordance
with the
Caution!
Malfunction as a result of unclear device status.
If replacement parts which are not downward-compatible are used in the wrong pressure reducers,
connected devices will malfunction.

Overview

2. Function
2.1 General
During operation, the oxygen coming from the
oxygen bottle passes through the bottle valve and
the connector 2 into the body 4 of the pressure
reducer. You can read off the bottle pressure (delivery pressure) at the contents gage 1.
WEINMANN piston pressure reducers are of
modular design. This makes it possible to keep the
number of replacement parts to a minimum.
A filter screw with integrated sinter filter (see explanation on right) traps any impurities. A further sinter
filter absorbs pressure surges in the oxygen flow.
The filter screw 12 is located at the entrance to the
connector 2. The second sinter filter is fitted between
the connector 2 and the body 4.
In the reduction stage the bottle pressure is reduced
to the required nominal outlet pressure, depending
on type. The principle used, with crater drill hole
and spring-loaded piston, ensures especially constant pressure in spite of variations in flow.
All pressure reducers are protected against excess
pressure by a safety valve 11.
Explanations:
Sinter filter: Small spherical bronze particles are
pressed together under heat, creating a filter with a
particularly fine pore structure (50 - 75 µm).
Flow: Outlet volume; expressed in liters per minute.
2.2 Fixed pressure reducer FIX
(WM 30050; 30100; 30200; 30300; 30350)
A fixed orifice in oxygen outlet 7 creates a constant
flow.
The pressure reducers in this series differ in the
length and position of the connector 2 and the
oxygen outlet 7.
2
7
Function
7
Page 8
2.3 Variable pressure reducer FINE (WM 30500; 30700; 30750)
The piston is acted upon by a second spring which
can be adjusted via a spindle system and thereby
creates different outlet pressures. In conjunction
with the fixed orifice in the oxygen outlet 7 you can
therefore make continuously variable adjustments
to the flow. You can read off the flow setting at the
flow gage 8.

2
The pressure reducers in this series differ in the
length and position of the connector 2.
7
2.4 Indexed pressure reducer FAST (WM 30600; 30800; 30850)
As in the fixed pressure reducers, this creates a
constant operating pressure (outlet pressure).
The index head 6 contains an orifice disc with
various orifice diameters which are aligned by an
index (click-in) system with the oxygen outlet 35.
This enables you to set various flow rates.
The pressure reducers in this series differ in the
length and position of the connector 2. A pressure
reducer of type WM 30850 has two oxygen
outlets.

2.5 Multistep pressure reducer Fast II High Flow (WM 31899)
As in the Fast multistep pressure reducers, there is an
orifice disk with a variety of orifice diameters in adjuster 6 which is brought into line with oxygen outlet 35
by means of a locating system.
35
In addition to the flow outlet, there is a pressure outlet
for medical devices with an oxygen requirement in excess of 90 l/min. The pressure outlet and the flow outlet may not be in operation simultaneously.

2.6 Two-stage pressure reducer OXYTRON (WM 30150)
The two-stage pressure reducer has a first stage in
the form of a fixed pressure reducer WM 30100,
and a second reduction stage 52 to permit optimal
adjustment of pressure and flow to suit the
OXYTRON oxygen device.
In the second stage the pressure of 4.5 bar from
the first stage is similarly reduced by a system of
crater drill hole and spring-loaded pistion to
1.6 bar.
A fixed orifice in the oxygen outlet 7 generates a
constant flow of 12 l/min.
2.7 Indexed flowmeter OXYWAY Click
During operation, the oxygen supplied by the central
gas system at a pressure of 4.5 bar passes through the
inlet connector 2 into the body 22 of the OXYWAY
Click.
The dial head 6 contains an orifice disk with orifices of different diameters which are lined up with
the oxygen outlet 35 by means of a click dial system. You can set the following flow rates: 1, 2, 3,
4, 5, 6, 9, 12, 15 l/min..

3. Final Check
3.1 General
Test conditions:
• Ambient temperature: 15 °C
• Ambient pressure: 1013 hPa
• Connection to oxygen supply. For flow tests, a
constant pressure* of 100 bar or 200 bar is
required.
* 100 bar up to SN 0849999
200 bar from SN 0850000
All the tolerances listed in these instructions (see
“10. Technical Data” on page 79) relate to these
conditions. Note that if different ambient conditions prevail, deviating measuring results may be
obtained.
For the check you will need:
• shutoff valve (max. 6 bar) after oxygen outlet
• test pressure gage 0 - 10 bar
• test pressure gage 0 - 2.5 bar
and three flow meters:
• 0 - 50 ml/min
• 0 - 20 l/min
• 0 - 220 l/min.
If the final check reveals faults, the device must not
be used until the defect has been rectified. For possible causes of the defect and how to remedy
them, see Chapter “5. Troubleshooting” on
page 18.
A complete check of the OXYWAY Fix, Fast and
Fine pressure reducer includes:
• Visual inspection for mechanical damage,
• “3.3.1 Testing system for leaks” on page 12,
• “3.3.2 Testing safety valve for leaks” on
page 13,
• “3.3.3 Checking “0” position of contents

3.3 Performing check
3.3.1 Testing system for leaks
1. Close system after pressure reducer, e.g. by
closing a valve after the pressure reducer.
2. Check that all screwed joints and hoses are
firmly seated. If necessary tighten joints by
hand.
3. Slowly open valve of oxygen bottle. Contents
gage 1 of pressure reducer now shows bottle
pressure, e.g. 200 bar.
4. To detect leaks, wet screwed connections with
a soap-and-water solution. Use Lanosan
for this purpose.
Warning!
Risk of explosion from soap penetration.
Leaks can cause soap to penetrate the system
and combine with the oxygen to form an explosive mixture.
• Open the O2 valve before wetting parts of the
system with a soap-and-water solution. The
system is then pressurized. No soap can penetrate the system.
• Remove the soap-and-water solution without
leaving any residues after the test is complete.
5. Close bottle valve again.
6. Observe needle of contents gage 1 for about
1 minute. If needle stays in same position, the
system is gas-tight. If the needle falls steadily,
there is a leak.
®
med
1
Eliminating leaks
We recommend that you keep a stock of replacement seals for the connections.
1. Prepare solution of soapy water, using perfume-free soap.
2. Wet all screwed joints with solution. If bubbles
form, this indicates a leak.
3. Release pressure in system:
– Close oxygen bottle valve.
– Open valve after pressure reducer until
contents gage 1 reads “0”.
12 Final Check
4. Replace faulty seal responsible for leak (see
“6.2 Replacing sealing ring in connector” on
page 20).
Important!
Screwed joints of oxygen line must only be hand
tightened.
5. Check for leaks again.
6. If leak cannot be eliminated, unit must be
repaired.
Page 13
3.3.2 Testing safety valve for leaks
1. Test must be performed at maximum flow. In
the Fine and Fast series this is set accordingly.
2. Slowly open oxygen bottle valve.
3. Test with finger whether oxygen is escaping
from safety valve 11.
If oxygen is escaping, have pressure reducer
repaired by manufacturer (WEINMANN).
Alternatively, you can also wet the safety valve
with soap-and-water solution to find leaks. Use
Lanosan® med.

• For WM 30200, 30300, 30350, 30850, 31899: flow meter 0 – 220 l/min.
1. Connect flow meter to oxygen outlet.
2. Close
– on pressure reducers WM 30850 and
WM 31899: oxygen outlet for adjustable
flow,
– on pressure reducer WM 30200: second
oxygen outlet (on the side).
3. Slowly open oxygen bottle valve.
– Contents gage 1 now shows bottle pressure
– Flow meter shows flow rate.
4. Check flow rate reading against set value.
Pressure reducers must maintain the following
flow rates:
WM 30050, 30100: 4 l/min ± 0.5 l/min
WM 30150: 12 l/min ± 1.2 l/min
WM (30200), 30300,
30350: 120 l/min ± 15 l/min
WM 30850: 90 l/min ± 10 l/min
WM 31899: min. 160 l/min
5. In the event of discrepancies, have pressure reducer repaired by manufacturer
(WEINMANN).
6. There is a second oxygen outlet on pressure
reducer WM 30200. This is a free pressure
outlet.
3.3.9 Checking static outlet pressure p4 for all pressure reducers
1. Connect appropriate test gage to oxygen
outlet 7.
2. Check closing pressures p4 (see “10. Technical Data” on page 79). They are valid for a
delivery pressure of p
* = 100 bar or
1
200 bar and must be reached within 1 minute
at most. After this they must not show any further increase.
* 100 bar up to SN 0849999
200 bar from SN 0850000
3.4 Checking the adjustable output (flow) on the OXYWAY Click
You need a flow meter with a range of 0 – 20 l/min.
Perform the measurement at an inlet pressure of 4.5 bar ±0.2 bar.
1. Set the flow "0" at index head 6.
2. Plug the flowmeter into a suitable compressed
gas supply (e.g. a central gas supply system).
3. Connect the flow meter to the oxygen outlet.
4. Set any flow value at index head 6.
5. Check on the flow meter whether the set value
corresponds to the actual value.
Please observe the tolerances of the flowmeter in
the process.
Rising test:
1 to 5 l/min: ±0.5 liter,
6 to 15 l/min: ±10 %.
Falling test:
6 ±10 % and 0/min: ±0.15 l/min

8. Replacement Parts
Note:
The item numbers in the following tables are the same as the numbers in the text of these Service and Repair
Instructions.
8.1 Information about conformity with standards
Up to serial number 0849999, OXYWAY
pressure reducers meet standard EN 738-1.
From serial number 0850000, OXYWAY
pressure reducers meet standard EN ISO 105241:2006.
In the course of adapting the products to standard
EN ISO 10524-1:2006, it was not possible to
design all components to be downward-compatible. Parts which are not downward-compatible are
available for both device statuses and are marked
accordingly in the replacement parts lists (see “8.
Ersatzteile” on page 69) of these instructions.
Caution!
Malfunction as a result of unclear device status.
If replacement parts which are not downward-compatible are used in the wrong pressure reducers,
connected devices will malfunction.
• Fit replacement parts which are not downward-compatible only in accordance with the
pressure reducer serial numbers quoted.
• Do not convert pressure reducers up to
SN 0849999 “to suit the new standard”.
