What is the purpose of an exhaust restrictor?

An exhaust restrictor is primarily used to manage the flow of air when an air cylinder is exhausting, which directly influences the speed of the cylinder's operation. By restricting the exhaust flow, the exhaust restrictor creates resistance that slows down the air leaving the cylinder. This resistance leads to a reduction in the speed at which the cylinder extends or retracts.

Lowering the exhaust flow allows for more controlled movement of the cylinder, which can be essential in applications requiring precision and careful handling of loads. The slower movement also reduces wear on the cylinder and associated components, making operations smoother and safer.

This function is critical in scenarios where sudden movements could lead to mechanical failures or damage, thereby ensuring the overall efficiency and safety of pneumatic systems.
