All hydraulic cylinders HZ are offered in two versions depending on the media used for the return stroke. Select between HZL (L=Air) for air return and HZO (O=Oil) for oir return. The TOX hydraulic cylinder HZL features absolute separation of air and oil, which enables a return stroke operated by compressed air (min. 3 bar). The HZO features special seals for oil/oil operation. It is possible to operate the return stroke with a max. 250 bar oil pressure. Please observe the max. allowable retract forces as shown in the table in the brochure "Pneumo Hydraulic Unit Type KT". Up to 6 hydraulic cylinders can be normally connected to one air to oil intensifier ES (more are possible on request).
