Application	Typical Direction	Typical Differential	Engineering Note
Cleanroom Positive	Cleaner room higher pressure	5-15 Pa	Menjaga udara luar tidak masuk ke area bersih.
Negative Isolation Room	Isolation room lower pressure	Min. sekitar -2.5 sampai -10 Pa sesuai spesifikasi	Menjaga udara terkontaminasi tidak keluar.
BSL Laboratory	Lab lower pressure than corridor	Umumnya negative cascade	Tergantung risk assessment dan exhaust design.
Pharma / GMP	Pressure follows cleanliness / process risk	10-15 Pa sering dipakai sebagai target awal	Harus mengikuti CCS, GMP, dan URS proyek.
