Validation for new AHU


(Tri Nguyen) #1

Hello there,

Our plant has many production rooms and we are using 20 AHUs for them. We have installed 2 new AHUs and now I want to conduct PQ. My question is: do I need to conduct PQ for the 2 new AHUs only, or I need to conduct PQ for all the rest 20 AHUs?

Thank you.

You required only two AHU for validation not for all.

Actually, our plant has more than 40 rooms. In the past, we used 3 rooms for solid-dosage form and now we want to produce effervescent tablet in that 3 rooms, that’s why we ADD new AHUs.

There is no problem with the old 20 AHUs.

Our plant is designed with dirty corridor which like this: corridor —> SAS —> production room. In my opinion, when the air movement and air condition in the 3 rooms change, in some ways it will impact on the air in the whole rooms of plant.

Hi, From my view point as I Understood that you added three rooms and installed 3 AHU didicated for them, so you only need to validate these three new AHUs only.
