Hi, Welcome to “I’m Serious” The theme of this episode is “How to operate air compressor simply” When it comes to Air Compressor, it’s very widely used. It can be used for home cleaning, waxing your car Ironwork, carpentry, the dentist even food processing and conveyor. Basically, we can divide two different types, regular air compressor, and oil-free air compressor. Speak of regular air compressor; it needs engine oil to lubricate, so the air was sprayed may have a little bit of oil. It has a very durable advantage. It can use in any construction site, full of dust, or a terrible working environment. It has the most annoying disadvantage.
It’s very loud like this How about oil-free air compressor? Of course, it doesn’t need oil. The theory is one suction (down) stroke down then compression (up) stroke up on and on. Pushing into compressor tank slowly. The biggest advantage is suitable for DIY or home use. When it turns on, it won’t like a regular air compressor so loud, like this. (We used microphone to make our talking sound clear so sounds no different, but oil-free sounds quite a lot. See, at least you can hear your own voice. But this one has been used for 15 years, so 15 years ago when it was young, it was more quite a little bit. What kind of place suitable for an oil-free air compressor? Like medical facility or your apartment, worries about disturb neighborhood, or food processing. What disadvantage does oil-free air compressor have? It’s cylinder and piston without oil to lubricate, it might be abrasion. But I never change for 15years. After we know regular air compressor and oil-free air compressor. Next, you need to know what is HP? HP is Health point MP is Magic Power. Ha HP is HorsePower. Am I right? Employee A: Yes. The power of a horse, energy of a horse, the capability of a horse? According to my high school physic teacher. What is 1HP? 1 HP is the energy of one horse pulls 33000 pounds one inch in a minute. What is different between 1.5HP and 3HP? When you use air compressor a while, the pressure of the compressor tank starts getting low, then air compressor starts working to refill air into compressor tank. The 3HP refills faster than 1.5HP of course. In my opinion, if only for home DIY or car cleaning, waxing your car, just spend 5000 or 6000 NTD, buy this size that will be enough. If you do painting job, painting size won’t over a person, 3HP is enough. I don’t recommend buying the tiny air compressor. It’s useless. If your workings place more like a factory or construction site, you need to use air spanner to remove tires or paint large object, there is no doubt, you will need 3.5HP or more. If you own a motorcycle store or profession-painting store I recommend 6.5HP or more. If your job is Car Beauty, needs many air hoses, everyone needs grinding and publishing, that I will recommend 7.5HP or more. (The capacity of compressor tank also will increase.) Besides HP, the Second point is the capacity of a compressor tank. The sizes to purchase and choose depending on your working environment. If you just start this career or carpentry or DIY metal material. I recommend this size will be enough (capacity is 25L), the size like this if you need to take it out, you can lift up on your own. When air compressor activated. The principle is like this. It will push air through air-filter, then after pressurize, the air will through this little tube and into your compressor tank. It principal like blows balloon, a balloon will inflate, compressor tank won’t, but the pressure inside the compressor tank becomes bigger than bigger. Now you can see this pressure gauge, this shows how many Kgs already pushed into your compressor tank. (The inside pressure of compressor tank.) So you need to notice one thing. There are a lot of different gases in the air, one of these is water. At this time, cause water is heavier than other gases, so water will sink to the bottom of the tank. You see down here is a drain cock. What is this drain cock for? When you open it. Hear that? I used work in the factory and painting factory, “release water!” it’s my favorite thing to hear. What is that means? It means off work. This is telling you, every day before getting off work or finishes your duty, please keep good habit that is open the drain cock. What will be affected? When there is water in your compressor tank the tank will get rusty, then get corrosion, next is less and less air can be saved. There is another thing as important as to open drain cock, That is when you use an air compressor, there is a jack behind must use stable electricity; don’t use a low-quality extension cord. Because when we pull cords there is 2mm copper wire in a while flat cord. If you cooper wire thinner than thinner, the resistance becomes bigger, will cause unstable electricity. So before using any electric products, keep a good habit that is using cleaner electricity or electricity with more stable voltage. Before plugin, we can use a multimeter to measure voltage, make sure is 110v or 220v. We will teach how to use a multimeter in the future, please remember subscribe. Let’s get start use air compressor. Before we start, turn off the on-off valve; turn on the power than you will see the pressure gauge rise slowly now it’s stop. Let’s take a look at the black circle; it’s a kg unit, so now the pressure is near to 8kg. Speak of air compressor; it must go with the air hose. It’s a comb just like soymilk with a fried breadstick. Pressure gun comes with the air hose. How to use it? When we need air hose to connect to the quick connect coupling.
Push back the coupling collar than insert your air hose, after that push forward the coupling collar, done, the collar will spring back; like this. There is a spring device inside. After the air hose is set, turn on the on-off valve, like this. So is full of air in this tube. To connect the air pressure gun. Just use your thumb and index finger pressing down. Insert your air pressure gun. Pressing back and done. Usually, if your air pressure gun already full of air. Just use thumb and index finger press down. It will hop up. My personal way is to use three fingers around this side down here. Use index finger and thumb to hold this two side up here. This will allow the following forces to go up. These two fingers go down. So when you pull out. Insert the tool you want. Insert, put in, done. If still hard to pull out. Just do one thing, turn off the valve at the front side. Release the air inside the hose. Now you can pull it again. Because there is air pressure inside. There is 7.5kgs air pressure pulls up. It’s hard to pull down by your hand. So at this time, just release the air pressure that won’t affect you to pull out your tool. Avoid spending too much time. After all set. Turn on the valve. It will full of air again. It’s easy, right? Ok, no matter big or small air compressor. The principles are the same. When you use your air compressor. Like me, holding the trigger all the time. Blowing the dust on my body. Blowing armpit. Blowing… Ok, hear it start pumping right? Because of the pressure in-tank lower than 5kgs, it will start refill to 7.5kgs and stop automatically. Ok, It stops. Don’t let it activate too long. All kind of machines needs rest. No matter how durable is or how famous is. It all needs let it stop to cool the temperature. If you use it every day, long time use, and have to grind, paint the large object. I recommend buying a larger one or larger compressor tank even to get the link tank. You need to let it rest! We need rest too. I’m tired. I’m exhausted cause filmed recently. How to use this advanced air compressor? It’s very easy. Just turn on the switch. Hear that? It’s already activated. Really quiet right? Unbelievable quiet. After you set up your air compressor, the second thing is set up your air hose. There are a lot of different material and different width, the thickness of the air hose. About the air hose, at the front part, chose the durable, bartolerance type.
