I want to take part in a pump injection model. How about these two? Anything else to introduce?

Ye Hong's pumps are reliable, but if there is no gas storage tank, the pressure of any pump is not particularly stable. More importantly, it is very important that the gas tank has the most effective water distribution function. Adding a fuel tank is about 100 yuan, but even if you buy a pump without a fuel tank, you can add a fuel tank afterwards, but it is a bit troublesome to modify it.

Without fuel tank, painted TC- 108 is good. I tried it at a friend's house, and the heat resistance was ok. This air pump just doesn't have a special gas tank. If the gas tanks bought afterwards don't match, it will take more time to rebuild. ...

In a word, both of them are popular air pumps, and their performance is almost the same. It depends on whether LZ needs to add a gas tank which mainly plays the role of stabilizing air pressure.

PS: Personally, I don't recommend low pump input. First of all, a good pump may accompany you for most of your life, which is a long-term one-time investment; Second, compared with the high-priced air pump, the low-priced air pump has a greater probability of cylinder explosion. The word "cylinder burst" is very dangerous ... pens can be gradually learned with the progress of your own technology after one or two years in into the pit, but water pumps often stick to their posts after you have bought two or three generations of spray pens. Therefore, it is more important than a good pen and a good air pump.
