Quality Assurance

Dear All,

Is there any measures we can take to control/Sudden backflow of airflow from packing area to filling area due to sudden or accidental pressure drop in B-area…i.e. installing mouse hole or something…

Thanks

If u have differential pressure alert alarm ,you can know the differential pressure is out of limit.close the mouse hole with SS plate using as damper.

Thanks Mr. manoj , but SS plate which will act as damper , will it be closed manually or automatic.it should be automatic but how it should be designed inside B area!?

It will be done manually. Just place the s.s plate at mouse hole when pressure drop occurs.
