Passa materiali MPSB

Device to be placed on the transit section between 2 rooms of different contamination class, to prevent the migration of particles from the dirtiest to the cleanest area.
The cleaning differential between the rooms concerned and the direction of flow of the materials to be transferred influence the
the configuration of the unit.

Made of double-walled, painted sheet metal or AISI 304 or 316 stainless steel panels, the pass box
The pass box has seamless internal surfaces. Removable shelves are available on request.
The hinged doors are fitted with a full-light transparent panel in polycarbonate or laminated safety glass with a metal frame.
with a metal frame. Treatment against the propagation of radiation is foreseen where necessary. Closure is by means of a magnetic or electromechanical device.

For large transit sections, up-and-down, roll-up, semi-rigid or flexible doors are available.
or flexible. Lighting, where required, is provided by wall and ceiling mounted LED or fluorescent sources. A command and control module manages and supervises the system starting from the transit request signal.

Passabox static

The MPSB device is a tunnel that passes through walls, which can be easily inserted in the structural modules, intercepted at both ends by doors, which are not operated simultaneously, and which can be operated by the operators or by a timed electromechanical interlocking device. The transfer is two-dimensional for sufficiently clean materials and involves rooms with a cleanliness class of less than or equal to ISO7.

Passabox ventiled

The MPSB AUT ventilated pass box is intended for the unidirectional transfer of materials, in ISO6 cleanrooms and better. Its self-contained fan filter apparatus, running continuously or timed, creates a laminar flow inside the tunnel that quickly restores the same cleanliness conditions as in the better classified cleanroom. If the flow of materials is bi-directional and the materials entering the cleanroom are clean, but contaminated with micro-organisms, the ventilated pass box is also equipped with ultraviolet radiation sources. The mode of transfer is subject to the implementation of a programme that matches the cleaning times with the opening of the doors.
