1.3 Use in accordance with purpose
The NitroFlow®Basic Mobile is intended to produce nitrogen out of normal ambient air. The system is based on gas
separation membranes. Each different or further use will not be in conformity with the purpose. Parker will not
accept any liability for improper use.
The generator is in compliance with the prevailing directives and standards. Only use this generator in a technically
perfect condition, in conformity with the purpose as described above.
1.4 User instructions
Only well-trained personnel are allowed to work on the generator. The user must be aware of hazards related to
operating the generator and processes connected to the generator. The user is responsible for the safety of the
personnel. All personnel working on the generator must have free access to the applicable manuals.
1.5 Liability
Parker will not accept any liability if:
xThe instructions in this manual are ignored.
xReplacement parts are used which are not approved by the manufacturer.
xThe generator is operated incorrectly.
xThe system is fed with other gasses than air.
xThe generator is modified without notification and authorisation of Parker.

2 Health, safety and environmental aspects
2.1 General
Correct use of the nitrogen generator is important for your personal safety and for trouble-free functioning of the
generator. Incorrect use can cause damage to the generator or can lead to incorrect gas supply.
Warning
xRead this manual before you start the installation and putting into operation of the
generator.Prevent accidents and damage to the generator.
xIf the equipment is used in a manner not specified in this user guide, the protection
provided by the equipment may be impaired.
xContact your supplier if you detect a problem that you cannot solve with this manual.
xUse the generator in accordance with its purpose. Refer to §1.3.
xOnly competent personnel trained, qualified and approved by Parker Industrial Division are
allowed to perform installation, commissioning, service and repair procedures.
xUnqualified people are not allowed to repair the equipment. Refer to §1.4. Lift the generator
with a forklift. Follow the legislation and instructions for operating the forklift.
xDo not tamper or experiment with the equipment. Do not exceed the technical
specifications for the generator. Refer to chapter 4.
2.2 Nitrogen and oxygen
The generator generates nitrogen as a product. Oxygen enriched air is released as waste.
Warning
xNitrogen can cause suffocation!
xOxygen-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!
xThe generator is not designed for installation in an Ex-classified area.
xDo not install the generator in an area where explosive mixtures may occur.
2.3 Electricity
Warning
xOnly service-engineers, qualified to work on electrical equipment, are allowed to do the
installation, maintenance and repairs.
xDisconnect the main power supply before you do the maintenance or repair.
xIf a service-engineer has to work on the generator 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
xMake 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.
xInstall the peripheral equipment, piping and nitrogen storage vessels according to
standard procedures. Parker cannot take responsibility for this.
xEnsure that regular maintenance to the generator is undertaken, to ensure proper and safe
operation. Refer to chapter 8.
xMake sure that instructions concerning health and safety are compliant with the local
legislation and regulations.

K3.1.114o Manual NitroFlow Mobile - 7 -
2.5 Environmental aspects
The use and maintenance of the generator does not include environmental dangers. Most parts are made of metal
and can be disposed in the regular way. The packaging of the generator 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 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 generator 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 Pressurised 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. Pressurised 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:
xOxygen and water vapor have a high diffusion rate and diffuse rapidly through the membrane wall.
xNitrogen has a low diffusion rate and diffuses slowly through the membrane wall.
Pressurised 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 generator.
5.1 Transport
Warning
xTransport the generator upright.
xPut the generator in the original box to transport the generator over longer distances.
xLift the generator with a forklift.
xFor qualifications of personnel, refer to §2.1.
5.2 Define location
IMPORTANT
xThe generator 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 generator on a fixed location. The location must meet the following requirements:
xMinimum clearance of 50 cm on all sides (back, left, right and top) as to facilitate heat removal
xIndoors
xDry
xNo continuous direct irradiation by sunlight
xAway from heat sources
xProperly ventilated room.
xEasy accessibly for operating and service
5.3 Unpack and check equipment
xOpen the packaging per instructions on the crate.
xMake sure that all components are delivered. Refer to § 4.1.
5.4 Connect nitrogen consumer
Warning
xDo not connect the power at this time.
xMake sure that the inlet and outlet tubes are free of dust, particles, metal parts and curls,
liquids and grease before you connect the generator.
Connect the product outlet to the application.
5.5 Connecting power
1. Connect the mains plug to a suitable wall socket with earth connection
2. The control system has input and output contacts for remote control and alarm signaling (refer to §5.6).
Warning
The main supply line voltage must be within 10% of nominal rated voltage for the generator. In
case of larger variations the generator will stop; continued use under these circumstances will
inevitably lead to motor damage.
