MityVac 7300 PneumaticVac - Air Operated Fluid Evacuator Review
Well, it works as expected. Hit it with 90 psi and it'll pull all the oil out of an oil pan or antifreeze out of a block. Because it drafts through the dipstick tube, the draft tubes are rather small which translates to a fairly lengthy evacuation time. For my 6.5L capacity engine, it took about 15 minutes to completely empty. And that's getting nearly 6.25L out, which is pretty empty! Properly cleaning the tank is a little cumbersome because of all the bolts on the lid. I like my equipment really clean when I'm through with it so I actually unbolt the top and clean and wipe the inside. Probably not necessary for most folks - a good rinsing with a solvent would suffice - but manageable nonetheless. Overall, I'm very pleased with the evacuator and would recommend it to anyone who doesn't want to remove a drain plug ever again. PneumatiVac Air Operated Fluid Evacuator This shop air operated evacuator provides a clean, fast and simple way to evacuate fluids. The base mounted Venturi adds stability during operation and the air and fluid-line shut off valves prevent the unit from overfilling during use. The reservoir is constructed of durable polyethylene and will not rust or corrode. This kit comes with 5 ft. of flexible hose, two rigid dipstick tubes and a universal brake-bleeding adapter. The PneumatiVac can also be used away from the air source by first creating a vacuum, closing off both shut off valves, then transporting the unit to the job. Connect the tubing; release the shut off valves, and the PneumatiVac will do the job! The PneumatiVac, a large 8.8 Liter (2.3 gallon) capacity air operated fluid evacuator, can be used to extract a wide-range of fluid types including: Engine oil from crankcases. Brake fluid from master cylinders and most hydraulic brake systems. Gear oil from transmission cases. Coolant from cooling systems. Power steering fluid from pump reservoirs.

A little pricey for what you get, and definitely not perfect but . . . - tela - UT, USA
First of all, if you want to buy this on Amazon, look around a little more here first. As of right now, Amazon has 4 different pages of 7300's with varying prices. Kinda confusing.br /br /I was very hopeful this would be a good product, and it is, but it definitely has its flaws. I tried it on two different cars. I drained the oil normally first in order to see if the vacuum got more oil out than just draining alone. It did, and a substantial amount on both cars too. I was pretty happy with this. I even used the hose to suck out the oil filter pipe which had even more oil.br /br /The biggest problem with this unit is the short hoses! They are so short that I had to pick the evacuator up and put it in my engine bay because otherwise the dipstick tube only went in a few inches. And these are normal size sedans too, nothing jacked up. I imagine buying longer hose at the hardware would fix this, but I wish they would have just put longer hoses on instead.br /br /The other problem is the way this pump is designed means it is always expelling lots of air, which means my compressor was on a lot more than I would like, cycling on and off. If you have a large tank you might be better off though. Also, the sound of the air rushing out and the compressor running makes for a noisy oil change.br /br /Oh, and forget the product description about pre-charging the unit and then taking it to the job site. That would last about 1-2 seconds of suction probably. This thing needs constant suction from your compressor to pull the oil out.br /br /I also used this to bleed brakes and a clutch. The universal brake adapter included is not that tight of a fit, and because of the short hose bleeding the clutch required me to put the unit on its side, which I had to do carefully so that fluid wouldn't go down the air compressor suction tube.br /br /The height of the thing can be kind of a problem too, especially when it's empty. It is prone to fall over. It does have a little metal thing to step on, but you can't always be by the unit when dealing with the hoses. I think they could have made this shorter and fatter.br /br /Another issue I had was removing the hoses from the unit. The rubber around the hose gets sucked on even more with the air pressure and removing it can be a pain, and several times the hose came out, but not the rubber piece that should have come out. I had to use pliers to pull it out once. I would recommend a screw type design instead.br /br /The only reason I am giving this item a positive rating is because it actually did get more oil out than draining alone did. I also plan on using this to change my coolant.br /br /If it was about - cheaper, this product would be just about right for how much it does and how well it does it. But at around , you might kind of feel ripped off.
Go with the pump, forget pneumatic - Chris T. Laquatra - Harrisburg, PA United States
I bought the PneumaticVac after the Dodge dealership informed me they wanted several hundred dollars for my 30k mile service in my Diesel Ram. br /br /The PneumaticVac performs as advertised, I used the middle sized plastic hose and one of the same diameter but longer I had to buy. It seemed this size was the fastest from under my truck. I set the compressor at about 100psi.br /br /This Vac couldn't hold my motor oil for me because my truck contains nearly 12 quarts from empty and this vac doesnt have that much capacity. But in the last few years I worked out a deal with a local garage for motor oil changes. br /br /In my adventure I found that most any garage or parts store will take used uncontaminated oil. (no anti-freeze)br /br /The hardware could have been a better design but like I said it worked saved me money. This vac saved me many times it's own cost in my first use. br /br /I might sell this one as used buy the deluxe model 07201 shown on Sears online, perhaps Amazon has this model as well. It looks much more rugged and as if it might have more uses than mine. br /br /I wasn't very happy about running my portable compressor for so long each time I used it. Not to mention long winded neighbors ears tend to perk up at sounds like the start up of a compressor... Next thing you know you've got an audience with verbal diarrhea.br /br /I needed a longer tube, dish deteregent, a hose, a role of paper towels for that unforeseen last drop that was present in the tube when I put the mightyvac away. (oh, and I could have used a decent pair of ear plugs or a 100lb dog for the neighbors)br /
