Use a general air compressor for power source . The boosing cylinder is not necessary any hydraulic unit to get a high output .

The high output of the oil pressure cylinder can be achieved by using the general pressure , and the hydraulic unit is not needed .

you can use the top nut to adjust the stroke .
