B3000 Filter Pressure Regulator
Instruction Manual
Intended use
Filter pressure regulator for compressed air or gases, for filtering and
reduction to a back pressure independent of the flow rate. Filter pressure
regulators cannot be used as flow rate regulating elements or stop valves. The
filter pressure regulators of the B3000 series include the function of a
compact spring-loaded pressure regulator. In addition to pressure control,
filter pressure regulators are equipped with a filtration and water separation
function.
The compressed air drawn in by the compressor contains countless fine dirt
particles that plug up openings when highly concentrated and at high speed and
make movable parts sluggish. When compressed air cools down, the dew point
drops, and larger amounts of water are separated depending on the atmospheric
conditions. The results are rusting compressed air tools, pneumatic
components, and pipe systems. The filter function separates moisture and
impurities from the compressed air, ensuring low- the maintenance operation of
pneumatic devices. The choice of pore size of the filter elements depends on
what is required. In the filter pressure regulator, the compressed air or gas
is first cleaned, then the pressure is reduced.
The filter pressure regulators of the B3000 and BM series are not equipped
with a twist cap. Therefore, by design, they are not suited for separating
liquids, only for filtering out solid particles.
The general function of a filter pressure regulator is described in the
following short movie.

Information on the usage instructions
Every handling of the device is under the condition that these usage instructions are understood and followed. The device is intended only for the application described.
2.1 Symbols
This symbol points out special information or mandatory or prohibited actions
to prevent damage.
These instructions serve the purpose of occupational safety!
This symbol is placed next to important instructions, for observing
regulations or if there is a risk of material damage.
Safety
3.1 Safety information
Do not endanger yourself or others. Read the following safety information
before you install, operate or repair fixtures.
They serve to avoid danger to persons and the plant. The handling of technical
gases – in particular flammable, self-igniting or toxic gases – requires
expertise, the observation of these usage instructions, and special safety
measures. Additionally, any relevant regulations and guidelines must be
observed.
(see 3.2)
Use the fixtures only as intended (see section “Intended use”). The same is
valid for the gas used with them: Improper usage can damage the system or even
lead to injuries that could be fatal.
Employ gas monitoring devices if you are handling dangerous gases. These
monitoring products detect leaks and warn personnel.
Wear a respirator mask, safety goggles as well as safety gloves if you work
with toxic gases and ensure good ventilation. Make sure that exhaust openings
cannot be plugged up and that toxic gases can be exhausted on fixtures and
plants accordingly with venting valves. Some gases can displace oxygen from
the air and cause suffocation. Make sure you have good ventilation when using
such gases. It is quite recommendable to install detectors that emit an alarm
in case of a lack of oxygen at the workplace.
Oils and greases must never be used on gas regulating systems. They can ignite
easily and react violently with some pressurized gases. In special cases,
lubricants can be used that are suited then for the respective application.
Implementing AirCom filter pressure regulators in oxygen applications is only
permitted with appropriately marked devices.
Special safety information for filter pressure regulators.
If devices are connected to the filter pressure regulator, it needs to be
ensured by special protective precautions that no dangerous pressure can build
up inside. The secondary venting of a filter pressure regulator (if equipped)
is not suitable as protection for these devices.
When changing the type of gas, the filter pressure regulator should be purged
sufficiently with inert gas.
For technical gases, use only filter pressure regulators with internal screw
plugs and without drains.
3.2 Regulations and guidelines
The following regulations and guidelines must be observed in Germany,
depending on the case:
- Principles of prevention
- Operation of working materials
- Guidelines for laboratories
- Ordinance on Industrial Safety and Health
- Datasheets “Hazardous substances”
Installation
4.1 Transport and packaging
When the filter pressure regulator is delivered, please check it for possible
transport damage or defects. The connection openings of the filter pressure
regulator may be closed for transport by caps to prevent dirt particles from
entering. Do not remove the caps until just before installation. In case of a
later disassembly, the connection openings need to be closed again before
being put into storage or transported. This can also be done provisionally by
a strip of adhesive tape that is taped over the opening. The transport of the
filter pressure regulator (e.g. sending to customer service) may be done only
in a suitable study package.
4.2 Preparation
Turn the adjusting screw (hand wheel, spindle, hexagon) on the filter pressure
regulator counterclockwise until the range spring is completely relaxed.
The system into which the filter pressure regulator should be installed has to
be depressurized.
Connect the filter pressure regulator – connection threads have to match.
To ensure the filter pressure regulator is in perfect working condition, all
lines need to be purged prior to installation.
Deposits and other foreign objects can cause damage to the valve seat, and
thus interfere with the regulating function or make it impossible. No
lubricants may be used during installation. The filter pressure regulator may
soil and there is a risk of burning out if oxygen or nitrous oxide is used.
The filter pressure regulator has to be installed in the line in such a way
that the gas flows in the direction of the arrows stamped/taped on the housing
(IN to OUT).
The installation position must be observed. The container always has to be at
the bottom.
4.3 Operation
The supply pressure has to be switched on slowly. The manual drain valve
has to be closed.
A semi-automatic or automatic drain valve does not close until an operational
pressure of 2 bar is achieved.
In the case of a filter pressure regulator with a manual or semi-automatic
drain valve, the condensate must be drained regularly; this is not necessary
for a filter pressure regulator with an automatic drain valve.
The desired output pressure is set by turning the adjusting screw (hand wheel,
spindle, hexagon). Turning clockwise increases the output pressure, and
turning counterclockwise decreases the output pressure. If the filter pressure
regulator is not self-relieving (without secondary venting), the medium must
be able to drain from the outlet of the filter pressure regulator; otherwise,
the outlet pressure will not be reduced.
The general function of a filter pressure regulator is described in the
following short movie.

Fine adjustments should always be made in the direction of pressure increase in order to reach the exact set point. The filter pressure regulators function with all media that are compatible with the specified materials. The filter pressure regulators may only be operated within the values specified in the technical specifications. An operation outside of the permitted values can overload and damage the seals.
Warning:
With some devices, “overtightening” the adjusting screw (hand wheel, spindle,
hexagon) can lead to a much higher back pressure than the maximum factory-
specified value. Operating a filter pressure regulator with a much higher
back pressure than the factory-specified pressure can have the following
consequences:
If the setting spring is compressed to a value near the block length, it will
show a greatly changed characteristic curve with a negative effect on the
regulating function of the filter pressure regulator (e.g. incomplete closing
of the regulator main valve, indicated by a creeping delayed rise or fall of
the back pressure).
The internal parts will be subjected to loads beyond their design limits,
which might deform them permanently.
Damages due to an excessively high setting of the back pressure are excluded
from any warranty.
4.4 Shutting down
- Close inlet.
- Consume the remaining medium completely or drain completely.
- Turn the hand wheel counterclockwise until the pressure range spring is completely relaxed.
- Once the pressure has been reduced completely, the housing can be opened for maintenance.
Maintenance
Do not carry out any maintenance/repair on fixtures that are under pressure!
Repair and maintenance may only be carried out by trained technicians! Under
normal operating conditions, an inspection is recommended every 6 months
during which the device is inspected for external damage and the function is
checked. If operating conditions are unusually excessive, shorter maintenance
intervals may be necessary.
5.1 Troubleshooting
- Problem: After adjusting the regulator, the back pressure continues to rise even without turning the adjusting screw (hand wheel, spindle, hexagon). Possible cause: The valve seat is dirty or damaged. Measure: Clean or replace the valve seat.
- Problem: Leak around or at the spring cap.
Possible cause:
-
Retighten the spring cap.
-
There is dirt or there are scratches on the valve tappet/diaphragm/piston. Measure: Replace the diaphragm /piston or the tappet (repair kit)
-
Problem:
Flow rate too low
Possible cause: The filter element is soiled.
Measure: The filter element needs to be cleaned or replaced. -
Problem:
Leak near or at the drain
Possible cause: Manual drain valve is loose; semi-automatic or automatic drain valve is soiled
Measure: Screw manual drain valve in tight; disassemble semi-automatic or automatic drain valve and clean or replace.
5.3 Spare parts
Only original spare parts may be used for repairs. Replacements are to be
carried out only by trained personnel. You can find spare parts at
www.aircom.net.
5.4 Repairs
Defective devices can be sent into AirCom Pneumatic GmbH. After a thorough
inspection, a cost estimate is created with the results of the inspection.
Filter pressure regulators that are not used with compressed air or neutral
gases need to be cleaned or purged with inert gas before they are sent in.
Additionally, the medium used as well as a fault description needs to be
listed in the cover letter.
