Stainless Steel Lab Laminar Flow Pass Box with Air Shower for Clean Room

Laminar flow pass box is a kind of auxiliary equipment of clean room, mainly used for the transfer of small items between clean area and non-clean area, and between clean area and non-clean area. In order to reduce the number of door openings of the clean room, the pollution of the clean room is reduced to a minimum. An ultraviolet lamp is installed in the transfer window, and the items enter the clean area after being irradiated by ultraviolet rays and sterilized. On the one hand, it acts as an air lock to prevent the high pressure in the high-level clean room from leaking. On the other hand, it achieves self-cleaning effect during the transfer process to ensure that the items entering the clean area are clean and reduce cross-contamination caused by objects .

Static Pass Boxes

These type of boxes are used to transfer material between 2 clean environments with little or no human intervention.

This box contains an electromagnetic interlock between the 2 doors and from a visual control point of view, an LED light suggests when any door is open.

Pass box Features:

Mechanical interlock is reliable, maintenance-free, fail safe and maintains cleanroom integrity by preventing both doors from being opened at the same time.

All Esco products are manufactured for the most demanding controlled environment applications.

All components are designed for maximum chemical resistance and enhanced durability for a long service life.

The main body of the pass box is constructed of industrial-grade electrogalvanized steel.

The pass box base surface is constructed of stainless steel, making the work zone easy to clean.

Acrylic doors provide a clear view of the internal chamber.

Dynamic pass boxes

This type of box is used to pass material from a non-controlled environment to a controlled environment.

Two interlocking doors on both sizes protect the controlled environment when any transfer takes place.

Depending on the application, dynamic pass box designs can be single door or double door (as shown to the right).

Dynamic Pass box Features:

Complete electronic interlock system and EASY LIGHT programmable timer.

High-efficiency HEPA FILTER H14 fluid seal, easy to remove and change from below – RSC (room side change)

Stainless steel perforated grille on the support surface, easily removed for cleaning;

No. 2 UV/C type germicide lamps inserted in the top section of the Pass-Box;
