AODD 10GPM vs 12V 5.5GPM Northstar

Roof Cleaning

I use an air powered AODD system for my roof washing rig and I compared with my friend and fellow washer Kenneth Collier (@Ken_32) from K Collier Services 12V System. We shot this Nov 1st.

The AODD system shot a stream of 42ft and a spray pattern of 30ft with an expected larger volume compared to a stream of 31ft and a spray pattern of 23ft with the 12V 5.5GPM Northstar pump.

The AODD system is using 200ft of Flexzilla 1/2 Air Hose and the 12V system was using 200ft of Kuritec 1/2 Hose.

Here is a link to my setup with links for what I am using:

12V 5.5 GPM uses a Northstar Pump found here:

My proportioner is self built and here is the parts list with links:

You’re welcome! Honestly I haven’t hooked it up yet. I haven’t done a single house wash so I figure I’ll do it this weekend or next week.

Just wait, when you get to spanish clay tile, 2.5 story house, 5.5k sq. ft, roof…slicker than a buttered otter! We just started on this one, this is the first application… look @ the gutter-line, nothing but soap…

Just downloaded it, works great for watermarking but what do you use to get them side by side?

Hey man, I want to upgrade and was wondering, I have a 7500 watt 120/240v generator also have a really expensive air compressor that I took out of my bucket truck (an old AT&T truck). I was wondering is there a reason to use air on demand over a 240v pump? I want 10gpm but it seems like the air compressor is just another big thing to add when you could just plug in a 240v pump right into the generator.

No experience with that so I can’t offer an opinion.
