    I have had my AV compressor well over a year and it works great. I use distilled water as per the instructions. BUT….. I was wondering if this needs to be changed periodically? And really want to know if it is safe to use some type of antifreeze with corrosion inhibitors? I watched a video with Tofazfou and his coolant looked bluish/purple. I was wondering if anyone has the AV and has used something other than distilled water long term? Thanks. Have a great labor day.

    Good question. I have had mine now for just about a year and I’m still running the same distilled water I put in to start with also, I see no reason to use anything else in it being it’s used indoors and I don’t need to worry about it getting too cold.

    Thats what Im thinking too. But im really more concerned with any form of corrosion inside. The reason I ask is the new Hatsan compressor uses car antifreeze with corrosion protection of at least 25% i believe. I wonder why?

    I have 179 hours on my Omega and was wondering the same thing yesterday and looked at the directions. This is what it says – maybe different for the AV:

    Change gear oil and radiator fluid after 3500 hours of use. Use non-distilled purified water, regular anti-freeze, and purple ice when filling the radiator. 16 0z. of radiator fluid. 1 OZ of purple ice, 1 Oz. of anti-freeze, and the remaining 12 – 14 OZ of fluid being non distilled purified water. in caps: DO NOT USE DISTILLED WATER.

    3500 hours seems like along time. At my annual fill rate, I'll be 140 when I need to service my compressor. I'm going to email Todd the AOA compressor guru to verify.

    Funny and the AV says use distilled water. So many different instructions.

    My Hatsan Lightning specs say use distilled water. Sometimes I wonder who writes these manuals up. My drain and refill for coolant is very 100 hours or every year, whichever comes first. Coolant ratio is no less than 25% antifreeze(G105 spec’d) and no more than 50%. I went with a 40/60 mix, with a few ounces of Redline’s water wetter solution in the mix.
