Del-Monox breathing air purifiers are designed to provide safe breathing air on a continuous duty basis for outlet air capacities ranging 15 scfm (25 Nm3/hr) to 940 scfm (1597 Nm3/hr). The engineered system employs six stages of purification to achieve specified breathing air quality levels.
Stages of Operation
Stage 1 DF Series Grade C:
One micron and general purpose coalescing filter removes solid and liquid contaminates
Stage 2 DF Series Grade A:
0.01 micron ultra high efficiency coalescing type oil removal filter removes virtually all liquid oil aerosols
Stage 3 Pressure-Swing Regenerative Desiccant Dryer:
Dependably reduces the moisture content to a level that ensures the effectiveness of the catalyst bed
Stage 4 Catalytic Converter:
Lowers CO concentrations by converting CO to CO2
Stage 5 DF Series Grade Y:
Particulate removal after filter removes contaminates one micron and larger from the air stream
Stage 6 DF Series Grade Z:
Activated carbon filter removes oil vapor and undesirable odors
For illustration purposes only, actual filtration is contained within the skid.
