Features of GC-300A

Unidirectional cable and hose

The power and control cables and the pneumatic hose are oriented in a single direction.
 

The primary current module contains a floating mechanism

The primary current module is equipped with a self-cleaning function and a floating mechanism.
 

Self-sealing coolant ports

The check valves of the circulating coolant ports are equipped with a PTFE sleeve to prevent liquid spillage.
 

Superior fail-safe locking mechanism

BL’s unique lock/unlock mechanism contains a mechanical fail-safe feature which does not allow the Master and Tool plates to uncouple if the air pressure is shut off.
