2 Tank

• Air Filters • Pressure Swing Adsorption Beds

• Automatic Pressure Cut-in/Cut-out • STS Patented BlastOff

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-lter to catch small particulates that

can cause damage. The recommended replacement for the pre-lter is 1000 run hours or 1-year,

whichever comes rst. Dirtier environments may need more frequent changes. Consult with the

supplier for a different lter maintenance schedule if installing in a dirty environment.

6.1.2 Air Filters

The generator has an air inlet pre-lters and two lters between the compressed air and O2

separation beds - the particulate and coalescing. The 5-micron particulate lter catches the bulk

particles, and the 0.1 micron coalescing catches the remaining smaller particles. Both lters

feature an auto-drain that drains any water buildup within the lter housing. These drain lines are

on the cabinet’s bottom right side. Connect these drain lines to a safe location.

6.1.3 Control Timer

An integrated control timer within 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

The installed ASME safety relief valves add additional safety to protect component failures.

6.1.5 Nitrogen Tank

A nitrogen tank inside the cabinet comes with ball valves, safety relief, and a gauge. The outlet

gas connects to an external manual ball valve for easy plug and play connection.
