Product Introduction

The static pass box creates an enclosed material route through a cleanroom partition without its own fan or filter. Its double-wall stainless body conceals the interlock outside the payload space, and the flush internal chamber can be wiped without ledges. This simple configuration is suited to short transfers between compatible clean areas.

Key Features

The concealed interlock is protected from impact by trays and cartons.

A lipless sill supports smooth, obstruction-free transfer.

Compression latches draw the door against a continuous perimeter gasket.

A glazed panel permits visual confirmation before access.

Mechanical or electrical one-door-at-a-time operation can be selected.

Customer Product Concerns

A passive pass box must preserve the wall opening and prevent direct room-to-room exposure.

A direct hatch lets air and particles pass between rooms.Two sealed doors create an intermediate transfer volume.

Exposed hardware collects dirt and is damaged by loads.The interlock is isolated behind the double-wall chamber.

Raised sills snag cartons and retain debris.A flush lipless transfer surface removes the ledge.

Door gaskets seal unevenly around the perimeter.Compression latches apply repeatable closure force along the door edge.

Typical Applications

Pharmaceutical packaging transferMedical-device componentsElectronics cleanroomsLaboratory sample movement
