I just got my cv1800 installed and ducted over to my table saw. I purchased the year end deal so it has a 16" impeller. So maybe its a cvmax. Anyways, I also installed a home made manometer so that I can tell when I need to clean my filters. I got the plans for it from the following link:

Towards the end of the video he says when the difference in the water level is about 2.5" you need to clean your filters. I noticed though while testing that for every blast gate I opened the difference in water level increased. So, the question is: How many blast gates should I have open to know when I need to clean the filters? Or is it simply a matter of marking the difference with one gate open and comparing the difference later on with the same gate?
On a separate note. When cleaning the filters, has anyone tried hooking up a small DC to the clean out box to suck the air out while blowing from the outside with compressed air?
