SINGLE ACTING COMPRESSOR
A Single Acting Reciprocating (piston) compressor consists of a single cylinder which only takes in and discharges fluid at one end.
5 of 12
DOUBLE ACTING COMPRESSOR
A Double acting unit also has only one cylinder but it is piped up to take in and discharge fluid at both ends.

ADVANTAGES
Oil-free compression due to hermetic separation between gas and oil chamber
Abrasion-free compression due to static seals in the gas stream.
Automatic shutdown in case of a diaphragm failure prevents damage
Discharge pressure up to (3,000 bar)

ROTARY COMPRESSORS
Rotary compressor function is in which fixed amount of air is displaced with each revolution.

ADVANTAGES.....
since suction and discharge valves (ports) do not exist.
Sroll compressors are considerably quieter in operation compared to other types of compressors, like for example reciprocating type ones.

DISADVANTAGES OF SCROLL COMPRESSORS�
Being fully hermetic, perhaps the biggest disadvantage of scroll compressors is that they are generally not easily repairable. They cannot be disassembled for maintenance.
