Vertical unidirectional-flow pass box with tall upper fan-filter housing

Equipement de décontamination du personnel et du matériel

Boîte de passage unidirectionnelle verticale par

A pass box that delivers a broad vertical filtered airflow over the payload and returns it through low-level channels.

Introduction de produit

The vertical unidirectional-flow pass box is designed for sensitive components that benefit from a stable downward air path. Its fan pressurises a full-ceiling final filter, while a perforated work surface and lower side returns continue the flow around the load. A velocity indication and door sequence help restore the airflow field after loading.

Key Features

A full-ceiling filter face limits dead zones above wide trays.

Lower perforated returns collect air along both payload sides.

The open support surface allows air to pass beneath containers.

An EC fan can compensate for normal filter resistance increase.

Airflow status indication supports routine operating checks.

Préoccupations du client produit

Critical transfers need broad coverage around the payload rather than a turbulent jet from one corner.

A small grille leaves low-velocity pockets over trays.A full-ceiling filter face distributes air across most of the chamber.

A solid floor blocks the downward airflow beneath containers.A perforated shelf and side returns maintain the path below the load.

Filter loading weakens the intended airflow.Fan adjustment and velocity display make the condition observable.

Loading-door turbulence remains when the receiving door opens.A programmed purge allows the vertical sweep to settle before release.
