Jofo

Jofo is a German manufacturer that started developing and producing hydraulic cylinders and pumps for the automatic opening of skylights in 1960. Later, pneumatic and electric cylinders and locking mechanisms were added. Since then, this leading manufacturer has a very extensive range of high-quality drives and accessories for skylights, lightdomes, and hatches used in N-SHEV systems and for natural ventilation purposes.
Beside its headquarters in Germany, Jofo products are also made in its own production facilities in France and Italy.

You can find Jofo products under different brand names. Especially the 230 Volt AC electric cylinders from the JM series have been used successfully for many years under many different brand names.
