Calculate the Ni Air Volume T in cubic feet per minute supplied in each zone, by using the formula:. The different media plates are exposed in every manufacturing section including the reverse air duct of the HEPA filter at the back of the cubicle.

Acceptance Criteria The smoke is to be taken by blower threw pre filter effectively with in the safe working zone and this should be very proper at the work table surface. Air Velocity Measurement Objective To demonstrate that the air system is balanced and capable of delivering air velocities as per requirement. The condition where the installation is complete with equipment installed and operating in a manner agreed upon by the customer and supplier, but with no vakidation present.

The sterile area is validated through following tests.


Dip it in Titanium Tetrachloride solution TiCl 4 and check for airflow direction from supply filter to safe working zone to return filter. It also helps in maintaining the area through filtered air. The distribution of smoke is observed. To demonstrate that the air system is balanced and capable of delivering air velocities as per requirement. Comments shall be published after review.
