Reciprocating double stage piston compressor
The air sucked in at atmospheric pressure is
compressed to the final pressure in two stages.
The compressed air enters the secondary cylinder after
passing through the intercooler, and the temperature is
greatly reduced. Compared with the single-stage unit,
the efficiency is improved. The final delivering
temperature can be around 120°C.
Single-stage and two-stage reciprocating
compressors are often used in car and truck repair
shops, body repair shops, service companies, and
industrial plants. Although this type of compressor is
usually oil-lubricated, hospitals and laboratories can
purchase oil-free compressors
