Clean Shop Air – Proper Flow & Pressure

Many shop air supplies have an oiler installed to provide lubrication for air

tools. The life of the filters in the NitroPro will be increased if the shop air

supply is free from moisture and oil.

Recommendation - install a separate air line without an oiler to connect to

the NitroPro. If this is not practical, consider installing a separate pre-filter

before connecting the NitroPro to limit potential contamination to the

NitroPro filters.

Also, ensure the shop air supply meets the pressure and flow ratings

stated in the NitroPro Operation Manual for maximum nitrogen generation.

PROCESS PARAMETERS

The nitrogen production depends on these parameters:

Flow rate The lower the flow rate of compressed air through the hollow fiber membrane, the more oxygen

can permeate through the membrane wall. As a result, the nitrogen produced at the outlet will

have a higher purity. Nitrogen purity can be adjusted with the flow control valve.

Temperature The NTF-15 Plus operates at a temperature between 40-110

F (70-80

F optimally). If the

temperature increases, the pressurized air consumption will also increase. Do not place the

system in a room where the temperature may rise unnecessarily high.

Allow enough piping between the compressor exit and the NTF-15 Plus inlet so that the hot

compressed gas has time to cool within the specifications listed in this manual.

Membrane pressure A higher membrane pressure will increase the capacity (i.e. nitrogen output) of the NTF-15 Plus.

Pressure also enables operation of the pneumatic pressure switch.

External pressure There must be atmospheric pressure at the outlet. The capacity and the purity of the nitrogen

gas decreases strongly if the vent pressure exceeds the atmospheric pressure.

UNPACK & CHECK EQUIPMENT

Ensure that all components were delivered.

Ensure that the compressed air source meets specification:

Oil content of the compressed air is below 0.01mg/m

Ensure that the compressed air pressure and quality is always as prescribed.

Ensure that the air capacity is sufficient.
