The items in this table are generally used for exhaust or fresh air systems; those used in air conditioning projects come in a wider variety. Otherwise, you’ll have to look for them one by one on your own
You can just pick any fan manufacturer; they should be able to help you choose the right model. However, choosing larger manufacturers ensures better quality, haha
