## Questions & Answers

**Q: What type of plastic is the business end made of? I need to move air containing acetone vapor/mist...Light duty work.**
A: Use with acetone vapor is a potential fire hazard, as the pump is not designed for use with flammables. Also, the plastic bits are an ABS blend and would likely degrade quickly with prolonged acetone contact.

**Q: Can this pump pull the bubbles out of resign or epoxy?**
A: It's not too bad for vacuum bagging but it's limited to about 19inches of mercury is about all it will pull.  I could tell the difference between parts bagged with this pump vs my pump that will get up in the mid 20's.  For bagging model airplanes with foam wings, it's plenty as you only need about 5 t0 7 inches.  I set mine up with a vacuum switch that's adjustable and run it from a 12v power pack or a 12v battery.  Well worth price if it fits your needs.

**Q: What kind of power source does this device use?**
A: Buy a gold or platinum+ certified PC power supply with the lowest wattage output (anything else is overkill) and wire the aspirator to the +12V and Ground rails from a Molex or SATA power cable.

**Q: Is this pump safe for pulling ethanol vapor out of vaccum assist filtration system?**
A: it is a membrane pump, so there  is no spark hazard - however it is only rated for air.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works better and higher quality than I first expected.
*by W***S on October 16, 2015*

FIRST a point of clarity: Another reviewer commented that the polarity doesn't matter. The terminals are NOT marked + and - which DOES MEAN you can pick whichever terminal you want to be +. Once you pick a terminal to be POSITIVE. MARK IT RED and DO NOT change them again. Changing polarity WILL matter IF you change rotation after running it in one direction for a while. You'll damage the brushes because the pressure and wear pattern on them will be reversed. THAT WILL slightly change the angle of the brushes at the contact point on the commutator . THAT WILL prematurely wear and destroy them. Not TODAY.... But it absolutely WILL happen. It is the reason why R/C electric car controllers using BRUSHED motors generally do NOT have reverse. Because of this it would be better to stick to convention, pick a terminal for + and STAY WITH IT. :-)I too, like another reviewer am interested in using it to vacuum seal. Specifically, I just want a poor man's version of a baggie sealer for food. This appears to be well suited to such a task. I am running mine from a 12v 2A SWITCHING pwr supply which I got HERE:HDView® 12V DC 2A 2000mA Power Adapter Supply UL Listed Certified 2.1mm 5.5mm, CCTV *** Best Quality ***It is a UL listed switching type supply and I measured 11.2 WATTS under full load on the PRIMARY side. Works excellently in this configuration. Add a small case, pwr switch and a simple filter ahead of it to prevent it f4rom sucking crap into the pump and VIOLA! you'll have a winner too! FYI, though (I) have not tried this, theoretically you should be able to get a deeper vacuum by daisy chaining 2 of these.. That is, provided the pump's internal structure doesn't bypass too early ruining the deeper vacuum.I also agree with another reviewer opinion in that the quality is much higher than I thought it would be.

### ⭐⭐⭐⭐⭐ usable for engine oil change
*by S***R on July 3, 2015*

Update: With a relatively strong plastic food storage box with a rubbery seal at the lid, 3/8" quick connect bulkheads, and 3/8" tubes for fridge ice makers or water filters, engine oil is flowing out continuously. I haven't measured the time but it's may be some 15 min for 6 quart. It is basically nothing if you change at home and surf the web in the mean time. The fastest and quietest and cheapest pump I have heard. I could try the serial connection with two pumps as one reviewer tested. But the 7 quart plastic box isn't holding up too well. If you block the oil flow, the pump can squash the box like what you can do to an aluminum can.I don't understand what's going on in topside engine oil change from the dipstick hole. I can use a hand vacuum pump to get oil out easily. Indeed it filled the small reservoir too fast and contaminated my pump. Why can't someone produce a decent pump for oil without waking up everybody in the neighborhood?This is it. I replaced this with my hand pump and it sucks just as great. How fast you need to take out less than 2 gal? I would say 10 to 30 mins. It doesn't matter for me even for a few hours. I was hoping to siphon the oil overnight but it didn't work. This pump is pretty quiet. It is much quieter compared to my silly tire compressor that worked like it's hammering something hard. My outdoor AC drowns it out, though my AC is not particularly quiet. My coffee bean grinder is louder! The point is since me and my neighbor can live with the AC noise, this pump is nothing in comparison.I have done some research and trials before settling on this. I had a metal hand pump oil changer. It's still in pretty good condition. For me hand pump is silly if you have the alternative. It's not like you can start the pump and the oil will siphon out by itself. You have to pump out every drop yourself. It's not like you add 40 strokes and the oil will all come out by itself. After the oil stopped coming out, I pull the pump handle (rather effortlessly) and some more oil come out. I pumped and then some more come out. It never ends. Unless you know how much oil is burnt away, and you measure the oil you got out, you are never sure enough oil came out.Actually siphon works for 1/4" tubes, but it is just too slow. Overnight cannot make it. 3/8" tubes will be a lot faster but it doesn't fit the dipstick hole too well, becoming airtight. I opened the oil cap and oil filter but still won't work. But there's no problem siphoning from container to container with whatever tube size.A good electric oil extractor is over a hundred, if not hundreds. But why? There's only one cheap oil pump on sale but some complainted that it is slow and I suspect that it's loud, like my silly tire compressor.So I wanted to build my own because I can do it with a handheld tiny vacuum pump. Also the oil can siphon out by itself but it's just too slow. It need just a little help. I've seen the guy using a vacuum cleaner and a homemade reservoir. It took 30 min. The problem is that I can't live with the vacuum cleaner on for 30 min. It would drive me crazy. My shop vac is just as loud. My carpet steamer is louder.I have looked at many pumps with oil in the title. But thick oil and thin oil are different. And for the application only positive displacement pump may work like gear pump and diaphragm pump. Oil will be in contact with the diaphragm and my ruin it if it's designed for water and cooking oil. There are some pumps used for racing that is almost certainly working for engine oil. But I think they are over kill.I tried this one because my handheld vacuum pump tester showed great promise. I could have used the vacuum from my car to drive a reservoir, but that pump is already working hard because of some subtle leaks in the system. It takes over $1000 to replace it. Also, this pump can be used to drive the AC in the car and my engine will work much better at idle and climb. (I noticed that a reviewer did just that.) As one reviewer said, the polarity doesn't matter. One of the connector will be the vacuum. I couldn't find an old 12V outlet adaptor that gives more than 1A. My battery is at the back too far away. I used an old PC power supply that is portable and overkill.As for the reservoir, you only need a big enough airtight juice jug and two bulkheads. I had them for pet projects to pump water. If the quick connect bulkheads don't work for vacuum, it have to work if I glue harder tubes into it. The 1/4" and 3/8" tubes fit each other perfectly, either for fridge ice maker or the softer clear vinyl type.update 2016: I finally figured out that the problem with this pump is that it's two powerful. The flow of engine oil is good, heated or not, until the plastic containers are crushed like aluminum cans. So I brought a vacuum release valve and bulkhead for it. I also used a 9V, less than 1A wall wart and it still crush plastic containers. As for tubings, polyethene tubes used for ice makers and also pneumatics are good. 3/8" OD tubings doesn't go all the way into the dipstick hole of my engine. 1/4" OD are a bit slow, but doable. Haven't try 5/16" tubings.

### ⭐⭐⭐⭐⭐ Good little pump
*by M***. on March 27, 2024*

good value for a small compact pump. I've only used it a couple times but it seems well made and pulls a decent vacuum for it's size.
