Yeah it’s a booster,they can take as little as 500psi and boost it to 3000 even up to 5000 psi.The booster will require a shop compressor to drive it and it will pump your scubas lower psi into another tank and boost it to your required psi you need .I have recently inquired about one that’s 600$ new but they are out of them for the rest of the year.:(Haskel makes boosters if I spelled it right.
The guy that made the 600$ booster may not make anymore and if he does they will be more expensive but he didn’t say by how much and he said at least a year before he would even consider making more.:(
The Haskel boosters are very expensive .
I was thinking about a mako 3300 psi scuba compressor and booster to easily reach 4500 psi of clean dry air.I had found a mako with only 250 hours and a fresh go over by Bauer for 900$ and add the 600$ booster for an investment of 1500$ for fast reliable air.lol dream got busted quick
