3.4 Description of function
The NTI 105 works on the principle of Pressure Swing
Adsorption (PSA). PSA is a process of generating nitro-
gen 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 oxy-
gen are adsorbed by activated carbon, which is an ad-
sorbent. The other gases are let out to the atmosphere.
During this phase pressurized air is let into another
tank. Again, the oxygen molecules are adsorbed in the
CMS. Nitrogen thus produced has a purity of about 95
to 99%. The nitrogen is collected in a tank for inflating
the tires.
The toggle switch (Fig. 1, Pos. 3) can be used to select
air or nitrogen filling. The selected gas is filled into the
vehicle tire through a filling hose. The NTI 105 should
be supplied with a constant supply of compressed air
at a minimum pressure of 8 bar.

4.1 Removing the transport packaging
!Dispose the packaging material in accordance with
local regulations. Do not dispose of the packaging
material along with household waste.
4.1.1 Opening the NTI 105
1. Visually, check if there is any damage to the packag-
ing case.
iIf there are signs of damage to the packaging, report
to the transporter immediately. Report the extent of
damage to Bosch Limited immediately.
2. Move the packaging case containing the NTI 105 to
the installation site.
iDispose the packaging material in accordance with
local regulations.
3. Remove the packaging.
4. Check if all the items/accessories listed in the deliv-
ery specification are available with the NTI 105.
iIf any of the items in the scope of delivery are not
delivered, report to Bosch Limited.
4.2 Installation
Requirements for installation:
RPneumatic supply - Pressure input of 8 bar to
16 bar.
RPower supply - 230 VAC +/- 10 %, single phase,
50 Hz
!Cover the NTI 105 such that it is not exposed to rain.
!Do not apply any cleaning agents to the display
(Fig. 1, Pos. 2), keypad (Fig. 1, Pos. 5) or the status
indication LED (Fig. 1, Pos. 9).
iFor optimal operation, ensure that the compressor
pressure is constantly above 10 bar.
iAs a good practice, you can install a 40 micron filter
/ water separator in the supply line from the com-
pressor. The filter should be able to function in the
pressure range of 8 bar to 16 bar. This is to ensure
that the particulate matter and moisture is filtered
from the compressed air even before it reaches
the FRC unit of the NTI 105 which, in turn, leads to
higher longevity of the CMS tanks.
1. Clean the surface of the NTI 105 cabinet with a di-
lute solution of detergent using a soft cloth.
iTo ensure optimum performance, ensure that the
input pressure is 10 bar or above. Also ensure that
the pneumatic connections are leak-proof.
3.4.1 CMS and nitrogen tanks
Two CMS tanks (Fig. 4, Pos. 1) are used to convert air
to nitrogen. The separated nitrogen is collected in a
storage tank (Fig. 1, Pos. 1) for further distribution. The
CMS tanks are firmly fixed and bolted to the cabinet.
3.4.2 Filters for water and oil separation
The input pneumatic line is connected to the Filter Reg-
ulator Combination (FRC) (Fig. 2, Pos. 1) which acts as
an input and filtration device. Air from the compressor
at a minimum pressure of 8 bar is passed through the
FRC where the moisture and dirt are filtered. The col-
lected moisture, dirt or oil can be discharged manually
by opening the drain on the FRC. The regulator is set to
allow a maximum of 10 bar.
!Do not tamper with the regulator setting of the FRC.
3.4.3 Hose for inflation
Air or nitrogen is filled into the vehicle tire via a 8 m
filling hose. A filling nozzle fixed to the hose is used to
connect the filling hose to the vehicle tire.
3.4.4 Keypad, pressure gauge and status indication
LEDs
Selection of air / nitrogen can be done via the toggle
switch (Fig. 1, Pos. 3). The pressure can be set through
the input keys on the keypad. The pressure sensor de-
tects 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. Upon completion
of service, the status indication LED (Fig. 1, Pos. 9)
glows.
3.4.5 Power cable and master switch
The NTI 105 is connected to 230 VAC  10%,
50 Hz  1% supply via a power cable. The NTI 105 can
be powered on by turning the master switch in the
clockwise position.

es via the valve block (Fig. 4, Pos. 2) and then to the
vehicle tire. The pressure is monitored by the pressure
sensor and the value is displayed on the LCD.
4.3.2 Direct outlet
If the filling hose is connected to the direct outlet
(Fig. 3, Pos. 4), the selected gas (air or nitrogen) by-
passes the valve block. Hence, the pressure is not moni-
tored by the pressure sensor. The tire pressure has to
be manually checked.

2. Rotate the safety valve (Fig. 3, Pos. 2) in the anti-
clockwise direction till the pressure in the nitrogen
pressure gauge reads 0 bar.
!Ensure that you tighten the safety valve of the tank
after releasing the pressure. If the safety valve is
not tightened, the nitrogen filled into the tank will
escape and the operating pressure of 8 bar will not
be achieved.
3. Loosen the hose clip that fastens the filling nozzle to
the braided hose.
4. Disconnect the filling nozzle from the braided hose.
5. Connect the new filling nozzle connector.
6. Place the hose clip and tighten the screws.
iEnsure that the orientation of the filling nozzle is in
the correct position. To check, connect the filling
nozzle to a tire. If the braided twists, repeat the
above procedure and adjust the position of the filling
nozzle.
