DIY Air Kit

There is a lot of dust in this world, dust collectors and vacu And inevitably, these t Including the option of vrcooling, it will give you the best price for the T We will try almost all the options available so that you can make the best decision about what is suitable for your space, the work you do and your budget. In one of my last videos, I discovered that a fan that I bought to move 4000 cubic feet per minute of air actually only moved 1340 CFM. There are some questionable figures, so to speak. I will tell you what I discovered so that you do not have to make a giant foam fan tunnel The two best ways to reduce dust levels in your space are with a high flow of air and an effective filtration medi I have talked about air filters in previous videos, so I will not go too deep into that today. In s All the air filters I tried So let's focus our attention on what t Without The more cubic feet per minute or cubic meters per second your air filter will work, the more dust will be able to capture. So to find out the real performance of a fan, I built t Measure the speed of the air in the cage of a fan can give you a wide range of results that are difficult to convert into significant data. For example, the air in the center of a fan has a zero speed and the edges have a What we really want is the average of these n A good way to find a way is to let the air mix in a wind tunnel and according to what I understood, when fans are tested in the manufacturer, they are placed in a test bench, something The motor and the fans of the fan can be tested by themselves, without the fan caudals that can reduce the air flow. We will not do that in the real world. The fan caudal helps us to keep ourselves safe. In fact, one of the only obstacles I had with my original filter unit is that a fixing screw was loosened and the fans of the fan fell off the motor one day. If there had been no cage to stop the fans, they would have shot themselves towards the filter box and could have destroyed everyt An increase in air flow does not justify that risk. There are some things that can change my n My wind tunnel of Islant foam introduces certain static pressure in the system that would not exist in any other way. Static pressure is the term of the sector for somet It can be produced by an air filter, a constriction or a curvature in a conduct or, in therefore, my test team is not perfect, but it reflects a more real estimation of the performance of the fan. The precision of t In fact, I bought another one to compare them between themselves and found that the devices vary in approximately 1-2%. As I do not need two of these devices, one of the first 100 people in comment will receive t Now, let's go to the tests. To determine the speed of the wind, the device is configured so that it takes a medi The wind tunnel can also be configured to give a square or round shape. Four fans were tested without any filter connected. These are the wind speed of the factory and the wind speed of the real wind. Some are quite similar, others are very far away. The brycold configurations that were tested are a single filter of 1-inch, a filter of 4-inch, a design of Corsi Rosenthal of 4 and 5 filters, and then my own air-detail filter with two different fans. There are other air-detail filters that are added to these figures were extracted from an excellent article by Wood Magazine that tested all these units. There is a link in the description to that and everything else you see I also was able to test the air-detail of someone and discovered that the classification of CFM of the factory was actually the exit of the device. That was the only time that happened w If we analyze some of these brycold options, the only air filter of the Lascaud has a sufficient performance. The Air King worked better with the filter of 1-inch and much better with a filter of 4-inch. At t Later in the video, I will show you some examples of t When we move on to the design of Corsi Rosenthal, we can see that the reduction in static pressure created by adding more area of filter surface significantly improves the performance of the Lascaud fan. Adding a fifth filter to the design increases the flow of air even more. The Air King fan increases that figure even more. I t My air filter in detail leads the group with 1,344 CFM with the two ventilators tested. Another t According to my research, t You can trace a beautiful circle in the air filter box with a pen and a rope. Then, cut it with a knife or, even better, with an X-Act knife. In some cases, the cover significantly blocks the fans of the fan in some examples I found. But even if you don't do it, I obtained exactly the same flow of air with and without t It is true that the air in the corners of the box fan actually invests the flow when the air filter is placed. Therefore, if you are trying to prevent the air from infiltrating through the front of the fan, t But if it waits for a significant increase in performance, it could lead to a disappointment. According to the concept of cover or fan conduct, what you want is that the fan is aligned with the fans of the fan. T However, if the fan cover is in front of the fans, there is not I am not 100% sure, but I t I only found an article or video where the air velocities were tested. What I am not sure is if the air velocity classifications were taken on the entire surface of the fan or if these figures were taken only from a single location of the fan. For the photos, it seems that the air velocity was not taken into account, w Take it with a pinch because, as I can say, the engineering dean of the UC Davis, Jim Rosenthal, wrote that article and it is possible that he also recognizes And I went to school to study video game design. So yes, t And its example uses two-inch filters, w But keep in mind that the two-inch filters are much more expensive than the one-inch. Speaking of expenses, let'see the performance in front of the price of all these models in dollars per CFM. I also calculated how much each one would cost after four changes of filter or two years of use. Then I did some more tests with the unique filter options, since they are the most affordable and I wanted to know exactly what you could expect from them. The dust of the air does not always overcome the process of compression of YouTube, but I hope you can see what happens here. For the filter to capture the dust of the air, I have to be directly in front of the fan. If I throw somet The four-inch filter works much better. I managed to attract most of the dust towards the filter. Even so, I have to be at least two inches away from the filter to get the best effect. One thing I This design is capable of vacu Therefore, after all these tests, the filter that I choose is still being. It is easy to clean dust traps, pieces and much more w Another use related to the foundation is to filter the vapor of the air while using my vacu Before installing the filter eliminates that smell completely. Another use I found is a quick and dirty painting cabin. The results are good, but I would definitely recommend using the fan only with a closed engine and not do it work when the temperatures exceed 90 degrees. It is Always remember to ventilate the space and use a respirator when working with I have another video planned for t It is about developing a large scale of room circulation and increasing even more the f. . .
