Review on 🧲 Mityvac MV7300 Pneumatic Fluid Evacuator with Accessories for Direct Engine Oil or Transmission Fluid Drainage via Dipstick Tubes, 2.3 Gallon Capacity by Thomas Silva

I received mine today. I added an air fitting and connected it to my 20 gallon compressor rated at 6.9 cfm at 90 psi. It seems high to me, but that's what he says. I bought it because of the name and the seemingly good reviews and it checked all the boxes for me so I could use my air compressor and it had a brake bleeder hose adapter along with the normal hoses for other fluids. It seemed to cover all the bases. Also, I live in the US. I don't care about the liter specification, it's only on this article. I don't want an apartment. If, as others have stated, the hard plastic rings are rated for quarts, then the owner's manual and box don't specifically state this. I also don't feel like I have to pour in a known amount of liquid and do my own line markings in a liter. The cover that the hoses go in and that goes into the extractor itself is a terrible design. The lid attaches with friction, and when you add a rigid tube there's nothing, I mean nothing, holding it in place except friction. If you tilt the hose at all, and you do, the cap will pop out. Semi-flexible hoses are pretty narrow, and if you suck in liquid and it comes out, any liquid you suck up will spill out of the hose and onto anything nearby. Let's hope you don't use a harder plastic hose for your brake bleeder hose because then you'll splatter brake fluid everywhere and better hope it doesn't get on your paintwork. it just made it come out more that way. Just terrible design. I was dying to use it so I sucked the cloudy washer fluid out of my car and was very surprised at how slowly the washer fluid came out. I then tried this with dirty room temperature oil from a previous oil change. He sucked in a few grams again, it was slower than I thought. It was very awkward trying to keep the tension on the hoses from loosening the cap and hose spring from the puller. You can't clean the inside of this bin if necessary unless you remove a few nuts and bolts. You don't mind much. Here you can pour some detergent, rinse and let it out of the drain at the top. Another thing I hate is that it's always "ON". That means if you connect the air hose, the venturi will always work. If you don't add a valve to the air hose to stop the airflow, air will always be used even if you're not sucking anything. This causes the compressor to use more air and lengthen the compressor cycle than it should. It also produces an unnecessary annoying hiss. The only on/off control for this extract is the actual suction line from the venturi to the tank. The valve opens the line only for suction from the tank. Really stupid design. I don't want to listen unnecessarily to my compressor working and hear the constant hiss of the suction when I'm not using it and the air hose is connected. I did quite a bit of research before deciding on this and now I'm 99 percent sure I'll get it back. I can probably make a metal bracket to hold the hose cap in the extractor, but that's not what I need to do with such a basic designed item. There is no F for design here. And I can add a valve to my air hose to shut it off, but I don't have to.
