196ZPA

Zero Pressure Accumulator Medium Duty Conveyor

The 196ZPA medium duty zero pressure accumulator conveyor employs pneumatic zone singulation to control product flow without causing back pressure on upstream units. This conveyor safely accumulates products by stopping individual zones while allowing live rollers at each end to maintain motion, supporting loads up to approximately 125 pounds per foot with standard roller and drive configurations. Using sensor rollers in place of traditional weight-activated mechanisms, this design reduces restriction challenges with lighter or uneven packages often encountered in typical handling environments.

The frame and mechanical components are engineered for continuous operation in distribution and manufacturing settings, with heavy-duty bearings, adjustable return rollers, and a robust channel bed that supports long runs and modular connections. Pneumatic actuation and a regulated airflow system provide consistent zone control, while the conveyor’s construction accommodates optional floor supports and elevation adjustments to integrate into broader system layouts with minimal system redesign.
