A reciprocating booster compressor has a minimum inlet pressure below which it will trip on a low-pressure safety switch. If the PSA pressure dips below this minimum during its cycle, the booster will trip \u2014 repeatedly \u2014 even though average PSA output is within the compressor’s specification. This is the most common cause of operational problems in PSA-booster systems.<\/p>\n
