Turn on the AHU and record the particle count for a 6 second period each minute, until the cleanliness level at the outlet is restored to the original condition. The intake fresh air is divided by the total air change in the room and multiplied by to obtain the percent fresh air intake on each cycle by the HVAC system in all the individual rooms. Switch ON the anemometer.

Hold the anemometer-fan about mm from filter face for measuring the filter face velocity and for checking the uniformity of velocity.

New study finds modified virus could stimulate immune validqtion on liver cancer cells. The sterile area is validated through following tests. Time taken to return to its original condition is called Recovery Time. Securing an orphan drug designation Published in PharmaTimes magazine — November In this article we will discuss about Air Handling Unit Validation procedure and test.

Photometer detect the leak of every 2 seconds.

If the observed deviation does not have any impact on the Qualification the final conclusion shall be provided. A discrete particle counter having a particle pharrma discrimination capability of 0. Dip it in Titanium Tetrachloride solution TiCl 4 and check for airflow direction from supply filter to safe working zone to return filter. Wait to stabilize the humidity in the area within the specification limit.
