Key Parameters For Breathing Air Quality
Breathing Air forms an important safety requirement and is often delivered by high pressure reciprocating compressors that are highly efficient in compressing air. Typically, the compressors used are either 3 or 4 stage units that can compress air from atmospheric (0 barg) up to 350 to 414 barg. A 4-stage unit is more efficient and reliable than 3-stages due to the lower interstage temperatures. Typically, the speed and power absorbed by the compressor dictate the charging rate and, in turn, the time to replenish a cylinder.
Breathing Air compressors are constructed to meet the Breathing Air requirements for continuously providing reliable breathing air quality, in line with CGA Grade D/E, NFPA (US) EN12021 (Europe), IS 15879: 2009 (India) or CSA Z1800.1-M85 (Canada) requirements.
