Safety
Safety Guidelines
PACE Nitrogen Farms are designed to utilise the latest polyimide hollow fibre membrane technology to
allow the generation of nitrogen from compressed air. The input compressed air pressure must not
exceed 8.5 bar/123 psi, it is important to ensure all compressed air hoses and fittings are maintained and
in good working order.
Disclaimer
PACE hereby disclaims all responsibility for any personal injury, property damage, fine, citation or penalty
imposed by any government or private entity which results from any use, misuse or mis-application of this
product, failure of the user to regularly maintain the product according to the recommended guidelines, or
failure to adequately monitor input and/or output air and the ambient workplace environment for the
presence of harmful levels of gases, fumes and particulates.
Compliance with all applicable environmental and personnel safety regulations is the sole responsibility of
the user and adequate self-monitoring of exhaust gases released into the atmosphere or the workplace
as well as monitoring of the ambient workplace air is strongly recommended.
To ensure continued effective performance, the following guidelines must be followed.
The basic principle of these products are that as compressed air flows through the hollow fibres contained
within the membrane body, oxygen is selectively allowed to permeate through the fibre wall to
atmosphere.
This results in a nitrogen rich gas being obtained at the output of the hollow fibre membrane.
There are three main factors determining the removal of oxygen from the nitrogen rich air.
a) Temperature - if this is maintained at close to 25°C then it can be ruled out of further
calculations of oxygen.
b) Flow rate - increasing the flow rate through the unit increases the level of oxygen present in the
output.
c) Pressure - increasing the pressure reduces the level of oxygen present in the output.
Features
• The NF1000 and NF500 are able to achieve Nitrogen purities of up to 99.9% on demand as stand
alone units.
• Extremely quick set-up times, because the system can be connected into an existing compressed
airline it can be positioned in minutes and is very portable.
• Low running costs: the NF1000 and NF500 require no power source othe r than compressed air.
• Using conventional bottled nitrogen can result in a nitrogen imbalance in the workplace. This
system recycles oxygen maintaining the correct balance of oxygen and nitrogen in the workplace.
The NF1000 and NF 500 contain no moving parts so do not give rise to noise or dust. No internal
calibration required.

System Set-Up
Connection and Operation:
The unit is connected to a compressed airline max pressure 8.5 bar/123 psi. Ensure that the compressor
is switched off whilst installing.
Compressed Air Supply:
Supply pressures should be regulated to the nitrogen farm at a lower value than the compressors
hysteresis to ensure constant operating pressure. The air supply should have no chemical, lubricant or
particulate matter added to the airline. It is however acceptable to use both dry and lubricated
compressors. Connection to the airline is made via ¼ BSP female fitting on the NF1000 and 1/8 BSP on
the NF500. Output of nitrogen rich air is also via the same size fittings.
*PACE recommends that you add internally to the system, a membrane dryer to be in line with incoming
compressed air supply, (see optional items list in manual).
Start-up:
1. Ensure the system pressure regulator is closed
2. Close off the flow regulator
3. Turn-on the compressed air to the unit
4. Open the system pressure regulator until gauge reads a nominal 7-bar/101.5 psi
5. Open flow rate regulator until desired rate is achieved (6 SLPM is the recommended starting pressure)
6. Run for 20-60 mins to allow system to stabilise before use.
Shut Down:
1. Close compressed air feed to unit
2. Leave open flow regulator
3. When nitrogen has stopped flowing from outlet, close system regulator flow regulator
Once running, both the flow rate regulator and the pressure regulator can control the level of nitrogen.
Maintenance
The units require no maintenance other than the replacement of the internal compressed air filters on a
once yearly basis, or sooner depending on the quality of the input compressed air. The filters are
essential to maintain the integrity of the membrane. The membrane will also need to be replaced from
time to time; this will depend on quality of the input compressed air, product usage and purity of nitrogen
required (approx membrane life based on average use 18-24 months).
Air Filter Replacement Procedure:
1. Remove screws from rear panel
2. Locate 3-stage filter module on left hand side of case
3. Unscrew each polycarbonate bowl in an anti-clockwise direction and remove
4. Remove filter element by undoing locking screw from underside
5. Replace new element by following notes 1-4 in reverse.
Membrane Replacement Procedure:
1. ENSURE UNIT IS DISCONNECTED FROM AIR SUPPLY!
2. Remove screws from rear panel
3. Locate 2 x nitrogen separator modules on right hand side
4. Remove retaining brackets to free nitrogen separators
5. Disconnect pipes from both nitrogen separators at top and bottom. This is done by pushing in
surrounding flange of fitting and pulling out pipe.
6. Remove nitrogen separators from case.
7.
Fit new separators by following points 2-6 in reverse. Ensure that when fitting pipes into connectors
they are securely located.

CAUTION
The system must be connected to a clean, dry, and filtered air supply regulated
To 7.0 Bar (101.5 psi) see "Specifications". Connection to a contaminated air
Supply or one with pressure in excess of 8.5 Bar (123 psi )
may cause damage to this system.
