Compressed air in cans for computers. How to choose and use - guide

Often, during diseases of the nasal cavity or pharynx, patients are bothered by ear congestion - tubo-otitis.

Tubootitis is an inflammation of the auditory tube.

The ear is part of a single system with the organs of the oral and nasal cavities. In case of inflammatory diseases of the nose or pharynx, the nasopharyngeal opening of the auditory tube, due to swelling of the mucous membrane, closes, and the tympanic cavity ceases to be ventilated - complaints of ear congestion appear, which signals an imbalance of internal and external pressure. At this point, professional ENT help is required.

The most common precursors of such conditions are:

• Previous otitis media;
• Swelling due to allergic manifestations;
• Impaired patency in the area of ​​the Eustachian tube after suffering from eustachitis;
• Inflammatory process in the oropharynx or nasopharynx, for example, sinusitis;
• Injuries to the inner or middle parts of the ear;
• Presence of wax plugs in the ears.

The following symptoms prompt people to make an appointment with an ENT specialist:

• Hearing impairment;
• Pain in the ears;
• Feeling of fullness in the ears;
• A special way of hearing one’s own speech is autophony.

The most primitive method of treatment, and therefore no less effective, is the Politzer method of blowing the auditory tubes. The method is absolutely painless and does not require anesthesia. It takes no more than 10 minutes. The effect occurs after the first procedure.

The appointment is usually made by an ENT specialist. ]Heratsi[/anchor], where the patient is served comprehensively and, a free visit to the therapist is included in the accompaniment of each patient, can accept the patient immediately for an appointment and procedure.

Also, ear blowing is prescribed when diagnosing the quality of patency of the ear canal.

This method has contraindications, so a mandatory consultation with a doctor is necessary.

Where to get quality compressed air

Alas, this is true. The prophets were right and now even air is for sale.

Compressed air is sold in cans of different types, and when choosing it in a retail chain, it is important to understand that you are buying compressed air in cans for a computer, and not for any other device.

Therefore, you should look for it in computer equipment stores in the departments of consumables and computer equipment care products. You can also find similar products on similar Internet sites. If you try to find something similar in other places, there will probably be certain problems associated with it.

This is because if compressed air is used for other purposes, it may contain third-party components, the presence of which can be very dangerous for the contents of the case of your computer, laptop or similar device that requires cleaning.

For example, manufacturers of compressed air for car repairs can add agents to it that prevent further destruction of car parts.

But the compressed air used by jewelers may contain components that, during operation, will allow microparticles of precious metals to bind together, since they can be reused in the creation of other products.

Tip: pay attention to where you purchase compressed air and the contents of the bottle. You can get it from the inscription on the label. For example, an unscrupulous seller may “pump in” air that is unsuitable for processing computer parts.

Tools and materials

Let's start with the fact that you need to have the following elements and tools on hand:

• steel wire;
• car filter;
• a large container into which paint and varnish materials will be poured;
• 20 mm clamp (it’s better if there are several of them in stock);
• board;
• self-tapping screws;
• 3 hoses, one of which will have a length of 400 mm, and a pair of others - 100 mm each.

In addition, you will need to have a drawing of such a device. You can do it yourself by calculating all the necessary parameters. Or it can be downloaded from specialized forums where people share various homemade products.

In addition, before starting assembly work, you need to find something that can be used as a receiver. For this, you can use a fire extinguisher, some unclaimed canister or a metal container that can be tightly and tightly closed.

Assembly

The process of creating the design in question will look like this.

1. First, we attach the compressor from the refrigerator to a wooden base.
2. Now you need to determine where the air from the compressor comes from. To do this, you can connect the device to the network and understand which of the 3 tubes is pumping pressure. Once this is done, the outlet pipe can be identified. This means that the second open pipe will be the entrance hole, and the third pipe is usually always sealed. It should be said that the sealed tube has its own important role - lubricating the compressor. So if the engine is running well, then it should not be touched.
3. Next, you need to attach hoses with the appropriate diameter to both open pipes, and tighten the joints using clamps.
4. Then, in the body of the thing that will act as a receiver, you should make a couple of holes where you need to attach the hoses. We attach a larger diameter hose to the inlet compressor tube, and a smaller one to the outlet tube.
5. You will also need to install a pressure gauge for the system. It is needed to gain control over the level of discharge pressure.
6. The receiver must be connected to the main structure of the load-bearing supercharger. After this, both parts should be connected to each other using the first hose, and the second pipe should be attached to the filter, which will trap small particles of debris and dirt in the air flow.
7. At the last stage you only need to connect the spray gun.

It should be added that if you want to make the resulting device mobile, then small wheels can be attached to its base.

How to use compressed air

Typically, compressed air is sold in metal containers - bottles, where the air is preserved under pressure.

The capacity of these containers may vary depending on the preferences of the manufacturer, but usually large-volume cylinders are not sold, taking into account the safety requirements relating to the product being sold.

Please note that in order to use the compressed air from the bottle, you must use the entire kit.

Yes exactly.

Compressed air is sold not just in cans, but in the form of a kit, which also includes a special nozzle in the form of a thin polymer tube.

One end of it, in the form of an adapter, is put directly on the movable nozzle of the cylinder, and the other is directed directly to the surface to be cleaned or an element placed on it.

Contrary to popular belief, you should not mindlessly press the spray valve. It is necessary to adhere to several strict rules that will save you from problems in the future.

Here are a few of them:

• the air stream must be directed directly at the object being cleaned;
• Do not release all the compressed gas in one spray;
• Pressing should be serial and short-term.

All these rules are strictly justified.

For example, short-term targeted pressures contribute to the economical use of air, because its pressure is quite enough to remove dust and a number of sticky contaminants.

Preparatory activities

To prepare for the operation, it is necessary to follow a strict algorithm of actions.

1. Clear the nasal cavity so that air can pass freely along its path in the stream.
2. Remove accumulated mucus formations by blowing your nose well.
3. Treat the mucous membrane using special vasoconstrictor solutions and compositions to eliminate swelling.
4. If the patient has a sufficiently high pain threshold, it is permissible to treat the nasal mucosa with analgesics.

How to replace compressed air

As noted above, replacing one gas canister with another can lead to irreparable consequences.

For example, flammable gas mixtures used for cleaning can cause a fire, short circuit, or poor cleaning. Similar situations may arise if the bottle contains humidified air or flammable gas.

Moreover, the consequences of cleaning with such a gas may appear not even during its implementation, but after, when the computer or other electronic device being cleaned is connected to the network.

When choosing a replacement for refrigerant cans (this is what manufacturers most often use), it is worth clearly understanding the features of using compressed gas and the purpose of its use. Accordingly, the gas directed into the housing must be dry, without additional impurities and preferably inert. Unfortunately, at home it is not always possible to comply with such requirements and you have to use something other than compressed gas.

How to understand when it’s time to clean your PC from dust and how often you should do it

You can tell that your PC is dusty by the rise in temperature. By installing a monitoring program, such as HWiNFO, and periodically looking at the maximum temperatures of the processor and video card, you will see their increase when dusty.

If you have a modern case with dust filters, then literally within a month they become clogged with dust, impairing the ventilation of the PC.

Make it a rule to clean the dust filters in the housing once a month. But the need to clean your PC from the inside is very individual. If the case filters work well, then cleaning the inside of the PC may not be necessary for even a year or a year and a half.

But at least once a year you need to inspect your PC from the inside and check for dust on the radiators. Even with filters, within a year or two the PC becomes clogged with tiny dust.

Alternatives at home

The two most common solutions to this problem involve the use of household appliances.

In the first case, this is a hair dryer , which not every computer owner has, and in the second, a vacuum cleaner . But even in this case, not everything is so smooth.

As for the hair dryer, when using it, it is important that it operates in a mode without heating the air. Otherwise, you can pay for the performance of the computer, since many of them, for example, laptops and tablets, can use glue that melts when exposed to high temperatures.

As for the vacuum cleaner, when using it, it is important to use the reverse mode, when air is not sucked in, but, on the contrary, blown out. This is necessary so as not to inadvertently tear out a soldered wire from the housing or, at high power of the vacuum cleaner, any other component.

This feature is not provided in every model, so be careful.

The correct way to use compressed air

Why clean your PC from dust?

Dust has several harmful effects on electronics.

Firstly, it worsens heat dissipation from radiators and microcircuits. Radiator fins clogged with dust stop blowing and overheating of the processor and video card is guaranteed.

The power supply circuits of components, various microcircuits, and HDD boards also suffer from dust and overheating.

But there is a place in a PC where dust accumulation can be extremely dangerous for your PC. This is the power supply.

It contains a whole scattering of filter capacitors designed for temperatures from 85 to 105 degrees. When the power supply becomes clogged with dust, the capacitors begin to constantly overheat and degrade. Sooner or later they fail, causing a power surge that can damage components. Or even start a fire.

Secondly, dust generates static electricity. Any manipulations in a dusty PC increase the risk of damaging the chips due to static.

Thirdly, dust is hygroscopic and perfectly pulls moisture from the air in humid rooms, causing oxidation of board contacts. This especially noticeably affects RAM contacts, which stop working normally.

How to make a spray can with your own hands

As a disposable consumable, the cost of a can of air seems prohibitive.

And although it is associated with a complex production process, many consider it unfounded. That is why some users are trying to make a similar tool for cleaning their computer at home.

This task is quite feasible, but not everyone can do it. This is because for its implementation it is necessary to provide several details at once.

First, you will need an empty container.

You can use, for example, an already used compressed air container, but in no case a varnish or deodorant container, since they may contain residues of alcohol or chemicals.

The second required component is a car compressor . It is this that will allow air to be pumped into the empty bottle.

And, of course, connecting elements - a car tube nipple and a fragment of a gas burner, which will allow you to connect the cylinder to the compressor and reduce air losses during refueling.

Important: It is important to be especially careful with this refueling method. Firstly, such a mixture cannot be used on all surfaces, since it contains flammable oxygen, and secondly, when refilling, the permissible pressure in the bottle must not be exceeded. Otherwise, it will rupture and cause injury or other damage.

How to make a homemade reusable compressed air cylinder for cleaning your computer?

This method eliminates the violation of the structural integrity of the cylinder by screwing, gluing or soldering bicycle, motorcycle or car nipples. This allows the cylinder to reach the pressure specified by the manufacturer and prevents the above items from being fired at the user. The role of a fuse when the permissible pressure is exceeded is played by a rubber tube with a clamp (do not tighten the clamp too much).

What is the effect after blowing out the ears?

Experienced specialists highlight a number of advantages of this method of restoring auditory activity. These include the following changes:

• Normalization of well-being. During a conversation, a person stops hearing extraneous sounds. Speech becomes more intelligible and clear;
• Preventing the appearance of wax plugs. Improper ear care is accompanied by the appearance of wax deposits, which form a foreign body. Their untimely removal is accompanied by the appearance of purulent otitis media;
• The technique of blowing out the ear canals allows you to normalize immune defense;
• Prevents the appearance of chronic and acute inflammatory processes in the middle ear cavity;
• Helps restore auditory function after serious illnesses;
• Removes congestion in the ears;
• The technique normalizes blood pressure and improves well-being.

To carry out this manipulation, you must have a clear understanding of the anatomical structure. Incorrect or sudden insertion of the rubber tip of the tube may cause deformation or rupture of the eardrum. As a result, the person permanently loses hearing function.

It can only be restored surgically using artificial material. As a rule, such a procedure is expensive and difficult to carry out.

Remember that when initial symptoms appear, you must urgently seek help from highly qualified specialists. This will normalize overall well-being and prevent further development of inflammatory processes.

Precautionary measures

In order not to harm either yourself or the device being cleaned, you should pay special attention to a few more rules.

As for the user, even when working with safe compressed gas, difficulties can also arise. They happen if the owner of the gadget is prone to dust allergies or asthma.

Allergic reactions when handling a computer are inevitable, since the air blown out of the case in concentrated form contains dust. To prevent it from getting on the skin, eyes or respiratory tract, it is necessary to use personal protective equipment:

• glasses;
• respirators;
• gloves.

It is inconvenient to work in them, but this is a necessary safety measure. Also, do not use compressed air for other purposes and do not direct it, for example, onto mucous membranes.

As for the device being cleaned, it must be turned off before processing.

Moreover, you need to wait until it cools down and only then proceed to the next stage. If the housing is collapsible, it is necessary to remove covers or removable walls to ensure comfortable access and unhindered dust removal.

Cleaning computer cases begins with moving elements, for example, cooler blades, then moves on to multiple radiator grilles (parallel metal plates) and only then begins cleaning printed circuit boards.

It is important not to scratch their surface and to do this, keep the adapter tube at a short distance from the board.

Disassembling a PC - step-by-step instructions

The PC can become so clogged with dust that even blowing it out won’t help, especially if it was kept in a humid or smoky room. In this case, only complete disassembly will help. And if the thermal paste on the processor or video card has dried out and requires replacement, the PC will also have to be disassembled.

Disassembling a PC will require your attention and accuracy. A Phillips screwdriver is usually enough for disassembly.

But it is better to buy a small set of tools, which will include wire cutters for cutting plastic ties, small screwdrivers and pliers. For example - 5Bites TK029 .
