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 validatuon the HVAC system in all the individual rooms. The condition where the installation is complete with all services connected and functioning but with no production equipment, materials or personnel present.

In this article we will discuss about Air Handling Unit Validation procedure and test. Compare the recorded values with Ref: Qualification Report shall include following:. Room in which the concentration of airborne particles is controlled and which is vaalidation and used in a manner to minimize the introduction, generation and retention of particles inside the room and which other relevant parameter.

The total air change is calculated. To demonstrate that the air system is balanced and capable of delivering air velocities as per requirement. Visitors are also reading: Photometer detect the leak of every 2 seconds.

Calculate the Total Air Volume T in cubic feet per minute supplied in each zone, by using the formula: In accordance with ISO Leave a Reply Cancel reply Your email address will not be published. Demonstrated by actual or videotaped smoke tests. 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 validatiion in which other relevant parameters.

The air velocity should be within the higher limit of HEPA filter. Scanning shall be done at the rate of maximum 2 feet per minute.

This should not take more than 15 min. Ensure that particle counter is purged by the purge filter supplied with the particle counter before the start of testing, till the reading obtained is zero.

The sampling probe should be positioned pointing to the airflow, in case of non- unidirectional vqlidation flow; probe should be directed vertically upward. 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. Quality Control Head —. Wait to stabilize the humidity in the area within the specification limit.

The Qualification report shall be reviewed and then approved by all functional heads of all the concerned departments. Particle count is taken before the operation as well as during the working condition.

HOW TO VALIDATE AHU IN INDUSTRY(AIR HANDLING UNIT)

Microbiology Particle counts Monitoring: Record this decay time. Air Handling Unit Validation Procedure: If the observed deviation has impact valifation the Qualification, deviation shall be reported to the concerned.

Distribute the calculated number of sampling location evenly in the clean room or clean zone or as per the authorized protocol at respective location. Hello sir My question is: The damper can be adjusted depend upon the design requirement.

It also helps in maintaining the area through filtered air.
