3.5 Description of function
The NTI 1000 works on the principle of Pressure Swing
Adsorption (PSA). PSA is a regenerative process of gen-
erating nitrogen from compressed air.
Compressed air is supplied through a pneumatic line
connected to a Filter Regulator Combination (FRC)
where moisture, oil and particulate matter are filtered.
Based on their molecular characteristics, compressed
gases have a tendency to adhere to solid surfaces
known as "adsorbents". The process of compressed
gases adhering to adsorbents is known as "adsorption".
When the compressed air is passed through a tank
with a Carbon Molecular Sieve (CMS), the molecules of
oxygen are adsorbed by activated carbon, which is an
adsorbent. The adsorbed gases are let out to the at-
mosphere. During this phase pressurized air is let into
another tank. Again, the oxygen molecules are adsorbed
in the CMS. The nitrogen is collected in a tank for inflat-
ing the tires. The nitrogen thus produced has a purity of
about 95 to 99%.
The toggle switch (Fig. 1, Pos. 8) can be used to select
air or nitrogen filling. The selected gas is filled into the
vehicle tire through a filling hose. The NTI 1000 should
be supplied with a constant supply of compressed air in
the range of 10 bar to 16 bar.

3.5.1 CMS and nitrogen tanks
Two CMS tanks are used to convert air to nitrogen. The
separated nitrogen is collected in a storage tank for fur-
ther distribution. The CMS tanks and nitrogen storage
tank are firmly fixed and bolted to the cabinet.
3.5.2 Filters for water and oil separation
The input pneumatic line is connected to the Filter Reg-
ulator Combination (FRC) which acts as an input device
and filtration device. Air from the compressor at 10 bar
is passed through the FRC where the moisture, dirt and
oil are filtered. The collected moisture, dirt or oil can be
discharged manually by opening the drain on the FRC.
3.5.3 Hose for inflation
Air or nitrogen is filled into the vehicle tire via a 12 m
filling hose. A filling nozzle fixed to the hose is used
to connect the filling hose to the vehicle tire. When
not in use, the filing hose is wound to the hose holder
(Fig. 2, Pos. 3).
3.5.4 Human Machine Interface (HMI)
A HMI unit on the front panel provides the control
needed for selection of nitrogen or air for tire inflation.
The pressure can be set through the input keys on the
keypad (Fig. 1, Pos. 4). The pressure sensor detects the
tire pressure. Based on the set pressure and mode, the
tire is filled with nitrogen or air via solenoid valves. The
result of the operation is displayed on the LCD screen.
A pressure gauge is used for indicating the pressure in
the nitrogen storage tank. LEDs are provided to indicate
the status of service.
LED status Indication
Red LED glows Completion of inflation or de-
flation
