We found our solution.
After watching this video I decide the 12v system was just to rinky dink.
I do not see how to embed a video in this post so here is the URL.
150 PSI 2.6 SCFM compressor.
Supports two divers and is used by some of the crews cleaning bottoms on the docks for a living.
A friend who was a professional diver cleaning boat bottoms bought the Harbor Freight
6 gal model and is happy with it. Another cruiser friend tried the 2 gal model but it did not give enough air.
A cruiser tried a friends Airline
system on his 40' + sail boat with a full keel and a 6' draft. He said he is over weight and smokes. He said he was scrapping with a wide scrapper and was breathing hard but the Airline could not keep up so he was looking for a compressor like the ones described here. So the success rates vary but we tried our DeWalt and it works for us great.
We here in Puerto Vallarta, Mexico do not have a “Harbor Freight”.
So we thought at Home Depot in Puerto Vallarta we could get the Porter-Cable 6-Gal. 150 psi Oil-Free Pancake Compressor but what were we thinking! No way, at least not now.
They may have had them at one time but not now. They could be dis-continued as I think the DeWalt one we bought could be. We do not see the DeWalt one on the DeWalt web site now. So we left Home Depot and went to a tool store. They sold some of the “Trooper” brand items but had no “Pancake Compressor” types. Then off to Bucerias to another tool store who said they do not carry the Porter-Cable 6-Gal. 150 psi Oil-Free Pancake Compressor any more. That their DeWalt 6 gal is over 4000 pesos (well over $300.00 USD) and to get it at Home Depot in Puerto Vallarta but he would have the water traps in next week. OK back to Puerto Vallarta and a stop at Cosco but no luck so then to Home Depot and pony up for the DeWalt 6 gal Pancake Compressor. Home Depot had another brand a “Husky” but we did not like it. There were too many parts exposed and it was taller making it hard for us to store. We paid about twice as much by the time we got the DeWalt out of Home Depot but we consider it money well spent. Actually it was about $100.00 USD over the non-sale price of the Porter-Cable 6-Gal. 150 psi Oil-Free Pancake Compressor. Things are just not easy here in Mexico when trying to buy a specific brand or model no matter what the store. Add in the language barrier as we speak limited Spanish. Debbie does speak some Spanish now but still it is hard to get the point across. We think we can run the DeWalt on the inverter and eliminate the Honda EU 2000i generator. The DeWalt draws 10 amps.
We will clean out the hanging locker soon so this compressor sit in here nicely.
So we went out and purchased a DeWalt compressor at Home Depot
. Fits in our forward hanging locker which is really a storage locker as our close are rolled up as they are not cotton, they are a light breathing easy dry non wrinkle fabric.
We had gone o the tool store in Bucerias, Mexico and ordered a water separator or water trap and then went back this week and they forgot to order it. He said that his friend at another sore in Mezcales had what we wanted (he called him) so we drover there but guess what. He did not.
So we had him order the one that we liked, this one. It will be in, in yet one more week but the bottom can not wait that long or it will get real hard to clean so we got a temp one for now. We went back to pick it up and now they say they can not get just the single you need to buy the double so we will keep looking
We did find a simple one that will get us by at an paint store with some more looking. We also picked up some nice air fittings that will not rust.
We also picked up some SS scrubber pads for cleaning the water line. At dinner with Danny and Debra on S\V Cyclades they told us these SS pads do a real nice job on the tough spots along the water line. We tried these or my wife did the water line and used these. Got all the grass and green and poo from macerating off the boat at the water line. They worked great.
Had to go to a truck brake hydraulic shop and get a 1\4" fitting crimped on the old Hooka hose to connect to the water trap or water separator. We also saw single air line fittings there of all types.
Then we attached the water trap and we good to go diving!
We used the DeWalt with the Honda EU 2000I generator and I was down cleaning the boat just over two hours. It was great having unlimited air! Got a real premium job done.
We set the PSI to 90 and this worked for air delivery to our 5' 6" draft or more because our water line is under water
We have abut a 40' hose.
