The FE4 Semi-Automatic Capper is loaded with standard features that distinguish it in the marketplace. With an impressive two-year guarantee on all parts, it assures durability and reliability. The machine's patented design eliminates the need for changeover parts for a broad range of standard caps and container shapes and sizes, streamlining operations.

Built for endurance, the capper is outfitted with a stainless steel 7’6” conveyor frame and a stainless steel enclosure with Lexan doors. This, combined with its stainless steel bolts and fasteners, makes for a robust machine ready to withstand demanding operations. Moreover, electronically controlled variable speed drives ensure smooth adjustments and optimal control.

User-Friendly Operation

The FE4 is designed for user-friendliness. Calibrated settings enable effortless and repeatable changeovers, and mounting facilities are provided for using a second set of bottle gripper belts. The machine is portable on four swivel wheels for easy maneuvering, and all parts are modularized for quick replacement, requiring little to no tools. Safety is paramount, with interlocking safety switches on Lexan guarding enclosure ensuring the machine will not run unless the doors are closed.

Customizable Options

Enhance your capper's capabilities with our variety of options. Choose from features like a stainless steel frame and cabinet table top plate, motorized capper head height adjustment, or the EM-980 Electronic Torque sensor, which records torques from the torque sensor onto paper. You can also choose to have an audible alarm and yellow flashing light indicator for low torque. With these options and more, customize your machine to best fit your operational needs.
