The F1 cylinders are thus the natural choice for customers requiring a high degree of traceability and documentation of applied materials and functions. The F1 cylinder has been tried and tested in many different applications – in a nutshell: Proven Technology.

Customer wishes accommodated

All special customer wishes can be accommodated according to the task requirements. Regardless of whether they apply to the choice of material for cylinder tubes, special types of housing, selected seals or other wishes, FJERO can adapt the design. This also applies to special surface treatments. FJERO’s cylinders come coated with black primer as standard, but can also be supplied as sandblasted and painted to corrosion classes C2, C3 or C5. FJERO can supply surface treatments in accordance with international standards such as ISO 12944-2 or NORSOK M-501.

If you DON’T require traceability or documentation, please refer to our F2 cylinder.
