PAC 78-FSP High-Precision Film Chopper - 460V - Ultra-Thin Material

Precision AirConvey High-Precision Trim Chopper | Model 78-FSP | 0.75 HP

The Precision AirConvey (PAC) Model 78-FSP is the industry standard for high-speed, inline trim reduction. Engineered for "Film Special Precision," the FSP variant is factory spin-ground to ultra-tight tolerances (as low as 0.00025"), allowing it to cleanly shear thin films, foils, and pressure-sensitive materials that would typically wrap or clog in standard cutters.

This 2005 unit (S/N 051434) is equipped with a premium 0.75 HP Baldor Electric motor and is designed for seamless integration into existing 4" to 6" pneumatic conveying lines. With its "shaftless" open-box rotor design and outboard bearings, the 78-FSP ensures 24/7 reliability and clog-free performance in even the most demanding converting environments.
