Room Pressurization within the pharmaceutical industry

Room Pressurization within the pharmaceutical industry

Room Pressurization within the pharmaceutical industry

(OP)
Can anyone advise me on which methods large pharmaceutical manufacturers such as Glaxo use to maintain constant pressure within their manufacturing areas? VAV?

RE: Room Pressurization within the pharmaceutical industry

I don't know exactly but can it be trough a differential pressure transmitter linked to VSD in HVAC motors?

RE: Room Pressurization within the pharmaceutical industry

In general , the VFD will be used to overcome the pressure drop across filter with its age and the differential pressure will be maintained by adjusting the exhaust dampers though pressure transmitter.

RE: Room Pressurization within the pharmaceutical industry

I am not sure about my answer but based on my understanding the pressure is generated by the air flow rate for that particular room and so if one can control the airflowrate then the air pressure can be controled. It goes back to air changes and air flowrate set for that room.

The flowmeter mesures the entry and exhit flowrates and hence the volume and controls it to the preset value to keep maintaining the pressure in the rooms.

I hope this helps. Do let me know if you have any different explanation or ideas.

RE: Room Pressurization within the pharmaceutical industry

I don't know about Glaxo but in the places where I worked the differential pressure was achieved with VSD linked to differential pressure transmitters.
