SAFETY NOTICE TO USERS
These instructions must be read thoroughly and understood before installation and
operation of your Peak Scientific NM60L. Use of the Generator in a manner not
specified by Peak Scientific MAY impair the SAFETY provided by the equipment.
When handling, operating or carrying out any maintenance, personnel must employ
safe engineering practices and observe all relevant local health and safety
requirements and regulations. The attention of UK users is drawn to the Health and
Safety at Work Act 1974, and the Institute of Electrical Engineers regulations.
WARNING: Nitrogen is not a poisonous gas, but if the concentration in the
inhaled air becomes too high there will be a risk of asphyxiation.

NM60L- Nitrogen Gas Generator UM – NM60L
AIR CONNECTION
The Nitrogen Generator should be connected to a clean, dry, OIL - FREE
source of compressed air. A minimum pressure of 120 psig is required for
efficient operation of the Generator. Any doubts as to the suitability of your
compressed air supply should be referred to the factory for advice.
A MAXIMUM OIL VAPOUR CONTENT OF 5 mg per m^3 is PERMISSIBLE
Air Inlet and Nitrogen Outlet connections are at the rear of the generator in
the middle right side of the panel. The Air inlet connection is the left port. 3/8”
BSP female, outlet port is 1/4” BSP female. The generator is supplied with
two Breathing Air pre-filters and an Activated Carbon post filter, which are
fitted internally. The Breathing Air filters will drain moisture and are equipped
with automatic drains. This is connected to the 1/4” BSP Female port at the
bottom of the rear panel. Any bulk moisture in the inlet air will be trapped by
these filters and released through this drain port, which should be led to a
convenient place.

NM60L- Nitrogen Gas Generator UM – NM60L
Principle of Operation Principle of Operation
Peak Scientific Instruments Membrane Generators utilise Hollow Fibre Membrane Technology to
efficiently separate Nitrogen from other gases present in ambient air. The membrane operates on the
principle of selective permeation in that so-called “Fast” gases such as H2O, CO2 & Oxygen will
permeate through the membrane wall whilst so-called “Slow” gases will not and continue along the
membrane tube and are thus available for collection and use.
Air passes into the system via the Breathing Air Filter. This will prevent bulk moisture and
harmful contaminants from reaching the Membrane. The clean air then passes into the
Membranes where Oxygen, CO2 and Moisture are removed allowing High Purity Nitrogen to
pass through. The Output Flow is regulated for pressure and then passed through an Activated
Carbon Filter to ensure no carry-over of harmful contaminants

NM60L- Nitrogen Gas Generator UM – NM60L
Commissioning Commissioning
With the Generator installed as described earlier. Disconnect the Nitrogen Outlet
connection to allow the generator to vent to atmosphere until the unit is stabilized then
open the air supply. The Generator has been pre-set in the factory to give the specified
output flow-rate and pressure. Once the Membrane reaches the design pressure the
Generator will stabilise and produce pure Nitrogen. Maximum purity will be achieved
after around 1 hour. After this time the generator can be re-connected to the
application.
The design of the generator is that it will deliver up to rated output flow of Nitrogen at
100 psig. Should the demand for Nitrogen be less than the rated output flow, or indeed
should the demand stop the generator will continue to operate without any problems.
The generator is protected from over-pressure.

Maintenance Schedule
WARNING: Servicing and/or repair of the Generator should only be undertaken by a
TECHNICALLY COMPETENT PERSON with the Generator in a safely isolated condition.
Due to the simplicity of the design and the small number of moving parts the NM Series Nitrogen
Generator will have a long and trouble free life. However as with all scientific and technical equipment it
should be regularly inspected and serviced as below
BA Inlet Filters Every 12 – months
RAC Filter Elements Every 12 - months
BA Inlet Filter Elements
These should be changed at 12 months intervals. In addition filter bowls should be cleaned and, the
operation of the auto-drains should be checked, if auto-drain requires replacing. Part # is (02-4485).
FAILURE TO FOLLOW THE PRESCRIBED MAINTENANCE PLAN WILL
INVALIDATE THE PRODUCT WARRANTY
The Air supply to the Generator MUST be turned OFF and the Generator MUST
be de-pressurised prior to attempting to remove ANY filter bowl. Failure to do
this may cause injury.
