Creating barriers for Humidity in a manufacturing area

Technical Questions
#1

Hello,

In our factory we have a warehouse and a manufacturing area separated by a bay door that is used so frequently that we leave it open at all times. I proposed using plastic curtain slats to maintain the humidity control in the manufacturing area to reduced the dry air coming in from outside through the warehouse.

The question came up if we could instead use air knives to create a barrier between the two spaces. Would an air knife be sufficient to slow the humidity/ air transfer or would plastic curtains be a much better solution in this scenario?

Hello,

First of all, if your process complies with ANSI/ESD S20.20, then humidity does not cause a concern for ESD control. All qualification testing should have been done at very low humidity conditions.

As far as your question about plastic flaps or an air knife, that is a bit out of scope for this group.
