Stainless Steel Pass Box Cleanroom Transfer Window Box

Pass box is a device which can block the air flow between rooms during material transfer from outside of cleanroom or between cleanrooms. It can prevent the contamination along with the materials and help to maintain the positive pressure in cleanrooms. The doors on both sides are respectively equipped with interlocking system. The doors have double glass window, and UV lamp for sterilization is installed inside to ensure the cleanliness of the materials in the process of delivery.

The dynamic pass box shall be equipped with centrifugal fan and HEPA filter. The clean air shall return to the plenum chamber through the perforated plates on both sides, then filtered air by HEPA filter evenly blow into the working area from the diffuser on top, the inner air circulation by this principle will achieve the purpose of purification.

Easy for installation;
Easy for operation and maintenance;
Versatile for different places and industries;
With the function of sterilization;
With electromagnetic interlocking;
Low noise centrifugal fan;

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;

Centrifugal backward curved radial fan with directly coupled inverter motor: power supply 230V, 50/60 Hz

LED indicator for checking and managing the cleaning status of the H14 absolute filter
