What is Air Handling Unit and Procedure & Tests for Air Handling Unit validation?
Non viable particle count. Responsible for ensuring the. Define the measuring plane perpendicular to the supply air flow and divide the measuring plane into grid cells of equal area.
The number of measuring points should be more than the square root of the measuring plane area in square meters and should not be less than 3 points Ref — ISO — 3 B. 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.
Ref — ISO — 3 B. Hold the fan of the anemometer till the anemometer reading is stabilized for at least 10 seconds duration and values should be recorded. Systems, which are not running continuously, run those systems 30 minutes before to stable system and measure the reading.
HOW TO VALIDATE AHU IN INDUSTRY(AIR HANDLING UNIT)
The number of measuring points should be more than the square root of the measuring plane area in square meters and should not be less than 3 points. Photometer detect the leak of every 2 seconds.
Photometer detects the leak of every 2 seconds. Distribute the calculated number of lharma location evenly in the clean room or clean zone or as per the authorized protocol at respective location.
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 air flow; probe should be directed vertically upward.
Collect the print out generated by the instrument after the testing and record the values of 0.
Compare the recorded values with Ref: ISO — I selected airborne particulate cleanliness classes for clean rooms and clean zone. Clean room takes to return from a contaminated condition to the specified clean room condition.
This should not take more than 15 min. In accordance with ISO Time taken to return to its original condition is called Recovery Time.

Unidirectional airflow pattern in which the point -to-point readings of velocities are within the defined percentage of the average airflow velocity. Room 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 room and which other relevant parameter.
For example Temperature, Humidity and Pressure are controlled as necessary. System composed of filter and grid support system or other housing mounted in the ceiling wall, apparatus or duct. 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. The condition where the installation is complete with all services connected and functioning but with no production equipment, materials or personnel present.
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 personnel present. The condition where the installation is functioning in the specified manner, with the specified number of personnel present and working in the manner agreed upon.
