2 Health, safety and environmental
aspects
2.1 General
Correct use of the NitroFlow®Lab nitrogen generator is important for your
personal safety and for trouble-free functioning of the NitroFlow®Lab.
Incorrect use can cause damage to the NitroFlow®Lab or can lead to
incorrect gas supply.
Warning
•Read this manual before you start the installation and
putting into operation of the NitroFlow® Lab.Prevent
accidents and damage to the NitroFlow® Lab.
•Contact your supplier if you detect a problem that you
cannot solve with this manual.
•Use the NitroFlow®Lab in accordance with its
purpose. Refer to §1.5.
•Only service-engineers, qualified to work on electric
and pneumatic equipment, are allowed to do the
installation, maintenance and repairs. Unqualified
people are not allowed to repair the equipment. Refer
to §1.6. Lift the NitroFlow®Lab with a forklift. Follow
the legislation and instructions for operating the
forklift.
•Do not tamper or experiment with the equipment. Do
not exceed the technical specifications for the
NitroFlow® Lab. Refer to chapter 4.
2.2 Nitrogen and oxygen
The NitroFlow®Lab generates nitrogen as a product. Oxygen enriched air
is released as waste.
Warning
•Nitrogen can cause suffocation!
•Oxygen-enriched air leads to increased risk of fire in
the event of contact with flammable products. Make
sure that there is adequate ventilation at all times!

K3.1.142e Manual NitroFlow Lab - 10 -
•The NitroFlow® Lab is not designed for installation in
an Exx-classified area.
•Do not install the NitroFlow®Lab in an area where
explosive mixtures may occur.
2.3 Electricity
Warning
•Only service-engineers, qualified to work on electrical
equipment, are allowed to do the installation,
maintenance and repairs.
•Disconnect the main power supply before you do the
maintenance or repair.
•If a service-engineer has to work on the NitroFlow®
Lab while the electric power it is connected, the
service-engineer must be very careful with respect to
the electric hazards.
2.4 Safety precautions
Warning
•Make sure that the ventilation rate is sufficient in the
room where the enriched oxygen is ventilated, or lead
the enriched air outside. Keep the ambient
temperature between 10 and 35 °C.
•Install the peripheral equipment, piping and nitrogen
storage vessels according to standard procedures.
Parker Filtration & Separation B.V. cannot take
responsibility for this.
•Do regular maintenance to the NitroFlow® Lab, to
ensure proper and safe operation. Refer to chapter 8.
•Make sure that instructions concerning health and
safety are compliant with the local legislation and
regulations.

K3.1.142e Manual NitroFlow Lab - 11 -
2.5 Environmental aspects
The use and maintenance of the NitroFlow®Lab does not include
environmental dangers. Most parts are made of metal and can be disposed
in the regular way. The packaging of the NitroFlow®Lab is 100%
recyclable. Optimal sizing of buffer tanks and setting of the pressure switch
will result in minimal energy consumption. The lower the delivery pressure,
the longer the lifetime of the system.
According to EC-regulations electrical systems have to be disassembled
and recycled at the end of their life. Parker Filtration & Separation B.V. can
support you in this.
Make sure that instructions concerning health, safety and
environment are compliant with the local legislation and
regulations.

3 Description of the appliance
3.1 General
The NitroFlow®Lab separates compressed air produced by an on-board
compressor into nitrogen and an oxygen enriched air stream. The
separation system is based on membranes.
3.2 Separation principle
A Pressurized air inlet
B Hollow fibre membrane
C Nitrogen outlet
F Fast permeation
S Slow permeation
Ambient air contains nitrogen (78.1%), oxygen (20.9%), argon (1%), carbon
dioxide, water vapor and traces of other inert gasses. Pressurized air (A) is
led through hollow fibre membranes(B). The various air components diffuse
through the porous wall of the membranes.
The diffusion rate differs for the various gasses:
•Oxygen and water vapor have a high diffusion rate and diffuse rapidly
through the membrane wall.
•Nitrogen has a low diffusion rate and diffuses slowly through the
membrane wall.
Pressurized nitrogen enriched air is released at the outlet of the
membranes (E) which can be stored in a nitrogen storage vessel.

5 Installation
Follow the paragraphs in this chapter to install the NitroFlow® Lab.
5.1 Transport
Warning
•Transport the NitroFlow®Lab upright.
•Put the NitroFlow®Lab in the original box to transport
the NitroFlow®Lab over longer distances.
•Lift the NitroFlow®Lab with a forklift.
•For qualifications of personnel, refer to §2.1.
5.2 Define location
IMPORTANT
•The NitroFlow®Lab contains compressors that
generate heat; for optimal performance and lifetime it
is necessary that cooling air can be vented without
resistance. A minimum clearance distance from walls
or other objects of at least 50 cm/ 20 inches on all
sides (back, left, right and top) is a necessity; also
efficient local ventilation at the ventilation outlet is
highly recommended especially when the device is
installed under a bench
Install the NitroFlow®Lab on a fixed location. The location must meet the
following requirements:
•Minimum clearance of 50 cm on all sides (back, left, right and
top) as to facilitate heat removal
•Indoors
•Dry
•No continuous direct irradiation by sunlight
•Away from heat sources
•Properly ventilated room.
•Easy accessibly for operating and service
