Overview
The new UL certified 3.2. cu ft vacuum oven comes standard with secondary over-temp protection dial, stainless steel internal tubing, stainless steel vacuum & vent valve, oil-filled vacuum gauge, and two year warranty. With our new internal shelf heating technology, each shelf in these ovens has its own heater, in-shelf temperature sensor and temperature controller, together with great thermal-conductive aluminum and our new low proportional controller technologies, the result is perfect uniformity, accurate temperature, super-fast heating rates, minimum heat loss/exterior temperature and very low power consumption.
The Ai 5.0, 7.5, and 16 cu ft vacuum ovens, come standard with secondary over-temp protection dial, stainless steel internal tubing, stainless steel vacuum & vent valve, oil-filled and vacuum gauge.
All AI vacuum ovens go through a 2-time 24-hour vacuum leak test, and is quality controlled in New Jersey or Nevada before leaving their warehouses.
Features:
- The 3.2 cu ft AT32x comes with 6 shelves (12 shelf capacity) in 110V 50/60Hz
- The 5 cu ft AT50x comes with 7 shelves (14 shelf capacity) in either 110V or 220V 50/60Hz
- The 7.5 cu ft AT75x comes with 9 shelves (18 shelf capacity) in 220V 50/60Hz
- The 3.2 cu ft AT32x comes with 13 shelves (26 shelf capacity) in 220V 50/60Hz
- The new KF25 inlet filter keeps your oven clean at all times (included with oven purchase).
- All stainless steel internal tubing provides a higher ultimate vacuum, holds the vacuum 10 times longer, and requires minimum maintenance.
- Oil-filled mechanical vacuum gauge provides more accurate reading, longer gauge life and minimizes shipping damage.
- All stainless steel vacuum and vent valves gives you cleaner connection, more accurate control and long term durability.
- 4th gen low proportional gain temperature controllers keep your oven temperature accurate
- Easy-to-clean stainless steel interior for exceptional durability and ease of maintenance.
- A vacuum environment lowers the boiling point (great for processing heat sensitive materials) and reduces drying time for materials like paste or powder which cannot otherwise be easily dried.
- Best choice for the curing and converting of oil extracts. With deep vacuum level, they can operate at temperatures which allow the degassing/purging process to occur rapidly, thus increase productivity and allow for the production of superior quality products with minimal processing time.
- Dual layer observation window with 3/4" (5/8” for the AT32x) tempered safety glass.
- Built-in swivel casters with leveling feet.
- Built-in alarm alerts you when oven has been shut down by safety circuitry due to out of range temperature.
- For improved temperature ramping, run the auto-tune procedure as outlined in the manual.
- All ovens shipped from our New Jersey or Nevada location for quick delivery.
- 2-year warranty and lifetime US-based parts and service support.
- Guaranteed US based phone and email assistance from an Ai support engineer within 30 minutes.
Attention: Before initial use, run oven at 200C/400F without vacuum for 15 minutes to burn off any residue that may have been introduced during the manufacturing process. NEVER LEAVE YOUR OVEN UNATTENDED WHILE OPERATING. Across International is not responsible for any loss of material inside of the oven.

Finally, a Toy That Out-Works My Dog!
Color: Blue
My dog gets bored easily, and this automatic moving ball has been a hilarious and effective distraction. It bounces and rotates on its own, which triggers her hunting instinct immediately. The rope chew attached to the side is a nice touch for some added teeth cleaning while she plays. It’s sturdy enough for a medium-sized dog and the fact that it's waterproof means I don't have to worry when she eventually drops it in the water bowl or takes it out into the melting snow. The *only* issue I have is it starts before I can even screw it back together. It wants to jump out of my hands before I'm ready.

My dogs think this is either terrifying or amazing
Color: Blue
I got this interactive dog toy thinking it would turn my living room into a fun little chase arena for my two small dogs. Technically, it did create excitement, but not in the way I expected. The toy rolls around unpredictably and wiggles its rope like it is trying to escape, which is honestly hilarious to watch. The movement is surprisingly energetic and the different speed modes keep it from feeling repetitive or robotic. The battery life is decent and it charges quickly, so it is easy to keep it ready for playtime.
Now for the comedy... my one year old Silky Terrier is normally the fearless one. He charges vacuum cleaners, interrogates delivery boxes, and believes he is the head of household security. However, the moment this toy turns on and starts moving, he suddenly remembers he has very important business somewhere else. He will sit at a safe distance and stare at it like it might file a police report against him.
The funny part is that when the toy is turned off, it instantly becomes his favorite object in the house. He happily grabs the rope, drags it around, chews on it, and proudly carries it like a trophy. Apparently his bravery only applies when the toy is not alive. I have discovered that in my house this is considered the acceptable mode of operation.
My seven year old Yorkie is even wiser. She took one look at the moving toy, processed the situation for approximately three seconds, and decided she would absolutely not be participating in whatever nonsense was happening on the floor. She calmly walked away and has maintained that policy ever since. She clearly understands this toy and wants no part of it.
Overall the toy is well made, entertaining, and definitely capable of keeping energetic dogs busy. Even if your dogs end up like mine and treat it as either a suspicious creature or a decorative rope toy, it still provides plenty of entertainment for the humans watching the situation unfold. If your dog enjoys chasing unpredictable moving toys, this one will probably become a household favorite. If not, you may at least get a very funny show out of it. 🐶

Just another reason to bark.
Color: Blue
I was so excited to come across this Interactive Dog Toy from Mewzoo, figuring that it would be a great way to give our dog some inside exercise during the rainy season that we have in this neck of the woods. It arrives with a charger, instructions and two ropes that can be tied to it, and it took about 2 hours to get it fully charged.
In order to get it moving, one needs to unscrew the blue plastic piece and that gives access to the control inside of it. It has three speeds, but the faster speeds only seem to lessen the time intervals for when it moves, they don't make it move any faster or further. This is kind of a bummer, because it really does not move very far, it mostly just stays within a foot or two of where it started. So not much exercise potential here, unless you consider barking exercise. Barking is one thing we do not need more of in this household, so this toy is a bit of a flop for us. I imagined that our boy might run circles around it and get a bit more hyper, maybe even grab it by the rope and carry it around for a bit. In the beginning I think he was fearful because he just barked at it of it, and then he decided it was time to eat. As you can see in the video, after only a few minutes with it, it looks like he's decided it's just a nuisance, lol.
The concept is good, and the toy itself is reasonably constructed to withstand some playtime. I just think it needs to have more movement and skitter around better to cover more distance. Then again at the whopping price of $10.99, i really can't complain.

Good interactive toy that keeps even my poodle mix busy
Color: Blue
We have a poodle mix that easily gets bored with most toys, including the other interactive bouncy balls. This toy seems to keep him busy though and so far he has not destroyed it or grown bored of it. The only problem we have is keeping it charged because he seems to wear it out but it is not a problem to recharge it with the USB cable that is included. It is a little tricky screwing the toy back together after charging the battery but I am getting the hang of it. Once it is set to one of the play modes the ropes on top (that you need to put on) will start spinning back and forth and the toy gyrates around seeming like it is alive to our dog. The loves playing with it in all of the modes but I think he likes that faster modes better. It comes with an extra rope which was good because our raptor dog already ripped the first one apart. The price on this toy is relatively low compared to tother toys to I highly recommend this for anyone that has a dog who is bored with the typical play toys.
