Any system needs redundancy in work needs pneumatics, because the COMPRESSOR of the pneumatic system has PERIODICAL operations (intermittent work, not as hydraulic pump). The COMPRESSED air could be accumulated in tanks with high pressures and used even if the compressor failed.

Pheumatic system is use in an APPLICATION where the load is light. Because if the load is heavy, pheumatic system should not be use & hydraulic system should be use instead.
