Review: Nice work tank for the shop - Using this tank to do simple AC tasks is a shop necessity and this works well
Review: High quality, works well. - I'm an ASE certified mechanic who purchased this along with a Robinair rg6 to do evacuations on car air conditioners to minimize refrigerant loss during servicing that requires removal of ac components. I just have to say, I had no idea what I was missing! Using this to store refrigerant over night allows me to purge air after leaving it undisturbed, and the liquid draw off allows me to pump it into the high side using the recovery machine which GREATLY speeds up ac filling. I wish I would have made this investment sooner! My tank is hydro'd until 2022, about 4 years from my purchase date! For the roughly $100 it cost at my time of purchase, it's absolutely perfect!! Keep in mind though that at the 80% full capacity for safety, it only holds about 24lbs so if you need to hold more, get a bigger tank. That said for vehicles 30 pounds is overkill. The port for a float sensor is perfect for cleaning oil out of the tank periodically.

### ⭐⭐⭐⭐⭐ CAN'T BEAT THE PRICE
*by C***R on January 21, 2014*

I've read the other reviews and just keep scratching my head. If the tank has non-condensibles from the factory you must boil them off with a good vacuum pump. And leak check prior to first use. That is standard acceptable practice in the refrigeration field. Just like the system you are working on. You must always vac and leak check any new work prior to filling with refrigerant. If someone got a leaky one from the factory just swap it out for another. I've bought the most expensive tanks available from the supply house and had the same problems noted in these reviews. It happens. I once installed a brand new oil storage tank on a dual-fuel system and discovered a leak in it while being filled. It happens. It's rare. But it happens. At least on a refrigerant recovery tank you can check for leaks prior to using it, unlike the oil storage tank I mentioned. A good vacuum pump should be able to vac to at least 500 microns of non-condensibles which is acceptable for all refrigeration work I'm aware of. If you are using a compound gauge look at the reading below zero when vacuuming. It should go down to at least 28 inches of mercury. (Vacuum can be measured in inches of mercury). If it goes there and stays after you turn your manifold set off for a reasonable period of time you know the tank is leak free. Vacuum isn't affected by changes in temperature like gas or liquid. So it is easy to leak check this way. I learned this the first semester in refrigeration school fellows. If you aren't qualified then steer clear of trying this type work. Get help if necessary. Contaminated refrigerant cannot be re-used. If you plan on re-using the recovered refrigerant in the equipment owned by the same person (which is the only legal way) you must ensure that the refrigerant is okay and you must recover it in a 'clean' fashion. Care must be taken to use a drier/filter and a vacuumed and leak free recovery system including the recovery machine and the tank and hoses. Got it today. vac'd it out with a high vacuum pump and tested for 1/2 hour for leakage based on other reviews. I did note there was a lot of liquid inside but was able to boil it off with the vacuum pump. Found no leak or further liquid boil. Vac held at 28 inches of mercury on my gauge. My practice is to always vac a new thoroughly in case I want to reuse the refrigerant. I then connected the recovery unit and vac'd that and the hoses with the tank valve open. Again no leaks or loss of vacuum. I was then able to start the recovery unit and remove the r-22 in the subject heat pump. No leaks after transferring to the tank. Perfect. Can't complain. The supply house wanted much more for the same thing. Remember, if you want to reuse the refrigerant you must thoroughly vacuum the entire set up including tank, recovery machine and hoses before you begin then leak check. There are no shortcuts in refrigeration work. And you must use a good quality high vacuum pump.
