Type DBZ

TYPE DBZ

CFM Air Springs type DBZ have a natural frequency between 1.4 Hz and 2.0 Hz, depending on size and operating pressure. At an operating pressure of 8 bar, a maximum load capacity of 186.1 kN per air spring can be achieved.

The type DBZ air spring is primarily used as a horizontal support element for specially supported foundations. The air springs have a high axial stiffness and a low lateral stiffness, hence allowing great motion.

DBZ air springs are of no or only limited suitability when applied as vertical springs.
