Product Information 

DURAPAC 

 Reciprocating Air Hydraulic Power Units are engineered to meet Industrial Standards for 

Performance and Safety.  The DPA-16 

model’s unique hydraulic circuit allows the quick displacement 

of hydraulic fluid under no load conditions and easy pumping in loaded conditions. These air 
actuated power units supply compressed hydraulic fluid to compatible applications i.e. cylinder, 
presses, spreaders, compactors and crimping machines, anywhere that 700 bar of fluid pressure is 
needed.
