  • 27, 03, 2021

Have you ever been in a conversation with someone linked closely to a pass box but gave up because you didn't understand the head or tail of what he was on about, or what was listed in the specifications list? We know it happens quite often, so we thought we'd break down some commonly heard basics as plainly and simply as we could for you.

1. Pass box dimension 

There are 2 factors relating to pass box dimension: the internal size and the external size. The internal size is more important because the internal size determines which materials will be transferred through pass box.

Internal size 500 x 500 x 500 600 x 600 x 600
External size 570 x 580 x 900 770 x 680 x 1200

2. Pass box material

Pass box is normally made of stainless steel. Some pass boxes have a powder-coated steel finish with stainless steel internal chamber surface. 

3. Interlock system for pass box

Pass boxes are equipped with mechanical interlocking or electronic interlocking system to ensure that the doors on both sides cannot be opened at the same time. 

4. Power

The power supply for pass box is about 220V

5. HEPA filter

HEPA filter used in dynamic pass box has filtration efficiency up to 99.99%
