Alternative to pressure multipliers or hydraulic unit. Functioning with normal air line from 3 to 8 bars Regulation of inlet air allows obtaining variable capacities and pressures. Stop automatic after attainment of pressure equilibrium. Automatic restart in order to compensate the pressure drop due to the oil volume decrease. Air pressure max 8 bar Maintenance of pressure for infinite time without power consumption. – Ideals for the feeding of high pressure circuits and for the control of: simple and double effect cylinders, short stroke cylinders, modules or equipments with multiple cylinders simple effect, or small presses for folding, marking, piercing, to rolling, blanking, punching and upsetting.
