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;
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

How the Laminar flow pass box works
1.Mechanical interlocking device: The internal interlocking is
realized by a mechanical form. When one door is opened, the other
door cannot be opened. The other door must be closed before the
other door can be opened.
2.Electronic interlocking device: The internal use of integrated
circuits, electromagnetic locks, control panels, indicator lights,
etc. to achieve interlocking, when one of the doors is opened, the
other door open indicator does not light up, telling that the door
cannot be opened, and electromagnetic The locking action realizes
interlocking. When the door is closed, the other electromagnetic
lock starts to work, and the indicator light will light up,
indicating that the other door can be opened.
