Leak Detection System
6.1.1. Air Compressor
An oil-less internal air compressor has an engineered dampening system reducing vibration
and noise throughout the cabinet. The air compressor has a pre-filter to catch small
particulates that can cause damage. The recommended replacement for the pre-filter is 1000
run hours or 1-year, whichever comes first. Dirtier environments may need more frequent
changes. Consult with the supplier for a different filter maintenance schedule if installing in a
dirty environment.
6.1.2. Air Filters
The generator has an air inlet pre-filters and two filters between the compressed air and O
2
separation beds - the particulate and coalescing. The 5-micron particulate filter catches the
bulk particles, and the 0.1 micron coalescing catches the remaining smaller particles. Both
filters feature an auto-drain that drains any water buildup within the filter housing. These
drain lines
are on the cabinet’s bottom right side. Connect these drain lines to a safe location.
6.1.3. Programmable Logic Controller (PLC)
An integrated PLC on the cabinet features smart timing to maximize the generator’s
performance. It controls the valve timing and sequencing to move compressed gas
throughout the system. It also has a smart feature to automatically switch between different
“modes” based on the current run stages (see Chapter 7: System Operation for more about
the unit’s functionality).
6.1.4. Safety Relief Valves (SRVs)
The installed ASME safety relief valves add additional safety to protect component failures.
