Diaphragm Air Cylinders

Rolling Diaphragm Cylinders

Friction-free conversion of pneumatic pressure to linear force

The advent of the long stroke rolling diaphragm as a means of low-friction dynamic sealing has led to the development of ControlAir's line of Diaphragm Air Cylinders. These cylinders provide virtually frictionless conversion of pneumatic pressure to linear force. The fact that there is no stiction or blow-by of any kind ensures accuracy, repeatability and sensitivity unheard of from conventional sliding seal air cylinders.

Small Bore Cylinders

Highly sensitive, low hysteresis, friction-free performance

ControlAir's Diaphragm Air Cylinders are also available in miniature versions. Small Bore models are based on the unique rolling diaphragm principle that virtually eliminates friction. The fact that there is no stiction or blow-by of any kind permits uncompromising accuracy and repeatability.
