Product Introduction

This conveyorized pass-through combines a cleanable stainless tunnel, transparent access doors at opposite ends, a continuous roller bed and a top fan-filter module. The control system sequences doors and conveyor movement so the two zone openings are not exposed simultaneously.

Key Features

Door interlock prevents both transfer openings from being open together.

HEPA-filtered airflow supports chamber purge between cycles.

Integrated rollers move compatible trays without entering the tunnel.

Transparent doors provide load and chamber visibility.

Smooth internal panels reduce difficult-to-clean ledges.

Customer Product Concerns

Frequent material passage can disrupt pressure separation and increase handling at the boundary between controlled areas.

Both rooms being exposed at onceThe control interlock permits only one access door to open.

Particles remaining after loadingA timed HEPA purge refreshes chamber air before the next door cycle.

Manual reaching into the transfer chamberThe roller conveyor advances compatible loads through the tunnel.

Poor cycle visibilityTransparent doors and status controls show chamber condition.

Typical Applications

Automated tray and container transfer between packaging, preparation, filling, inspection and controlled storage zones.

Technical Parameters

Chamber length, conveyor height, door actuation, purge timing and roller drive are configured around the material flow and room pressure strategy. Sensors and programmable controls coordinate load detection with the interlock sequence.
