The air velocity should be within the higher phrma of the HEPA filter. Record the data in the format. Dedicated space in which the concentration of airborne particles is controlled and which is constructed and used in a manner to minimize the introduction, generation and retention of particles inside the zone and in which other relevant parameters.
HOW TO VALIDATE AHU IN INDUSTRY(AIR HANDLING UNIT)
Dip it in Titanium Tetrachloride solution TiCl 4 and check for airflow direction from supply filter to safe working zone to return filter. Responsible for ensuring the overall Re-Qualification of HVAC system, used to validxtion the environmental conditions of all areas. The Qualification report shall be reviewed and then approved by all functional heads of all the concerned departments. 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.
Ensure that particle ahi is purged by the purge filter supplied with the pharna counter before aahu start of testing, till the reading obtained is zero. The pressure difference is generally kept between 5 — 20 mmHg pressure. Hope above information ij helpful to you. Your email address will not be published.
Hold the anemometer-fan about mm from filter face for measuring the filter face velocity and for checking the uniformity of velocity.
The microorganism count should be within the range and if it is found out of specification for consecutive two times, an effective corrective and preventive action is taken. In this article we will discuss about Air Handling Unit Validation procedure and test. When incubation observe carefully and record the no. These are performed to validate whether AHU is working accurately as per standard operating procedure.

The particles should be count when more than one hour falidation has been progressed in the area. Log In Remember Me. Procedure Take a glass stick with cotton or sponge tied to it. Ankur Choudhary is India’s first professional pharmaceutical blogger, author and founder of Pharmaceutical Guidelines, a widely-read pharmaceutical blog since Non viable particle count.
There are 10 most used validarion processes. C Air Supply cubic ft. To demonstrate that the air system is balanced and capable of delivering air velocities as per requirement.
Define the measuring plane perpendicular to the supply pharm flow and divide the measuring plane into grid cells of equal area. Compare the recorded values with Ref: Sign-up for the free email updates for your daily dose of pharmaceutical tips. Particle count is taken before the operation as well as during the working condition.
