DB Series Nitrogen Generator
DB5-20 Model
2.4 Inlet Air Quality Requirements
To achieve the maximum performance, reliability and service life, the proper combination of
compressed air treatment equipment must be installed upstream of the generator.
Parker recommends that PSA nitrogen gas generators receive inlet air quality in accordance with
ISO 8573-1:2010 Class 2 for Particulate, Class 2 for Water and Class 2 for Total Oil. This requires a
combination of compressed air filters and a desiccant dryer.
Refrigeration dryers will only provide air in accordance with ISO8573-1:2010 Class 4 or Class 5 for
Water. For refrigeration dryer users, an oil vapor removal filter must be installed downstream of the
dryer and upstream of the generator. Inlet air quality to the generator must be in accordance with
ISO8573-1:2010 Class 2 for Particulate, Class 4 or Class 5 for Water and Class 1 for Total Oil.
Operation outside of these conditions can result in performance degradation and/or permanent failure
which may void factory warranty.
2.5 General Mechanical Requirements
Familiarize yourself with the local regulations before considering any pipework/hosing installation.
Many of the processes that use nitrogen are of a critical nature. The removal of dirt particulate, oil
and water vapor from the gas stream is also essential. Therefore, the pipework system and material
that will transfer the nitrogen to its destination should not add any unwanted contamination into the
gas stream.
All components used within the system, including pipework and the compressed air treatment
equipment, should be suitable for compressed air duty and of a size and construction to handle the
maximum pressures involved.
Ensure that all pipework/hosing is adequately supported to prevent damage and leaks in the system.
The diameter of the pipes must be sufficient to allow unrestricted inlet air supply to the equipment and
outlet nitrogen supply to the application.
All buffer and storage tanks should be fitted with suitable pressure gauges and pressure relief valves.
Parker recommends that ball valves are connected to the buffer vessel ports to allow it to be isolated
during maintenance activities.
The system must be protected with a suitably rated thermal pressure relief valve upstream
of the generator.
