👍Best Compressors for Refueling Cylinders for 2020

When diving, it is important to take into account many features to make the dive safe and comfortable. The first thing a diver needs to know is the cylinder design and the correct filling. This will help you get out of trouble.

But also time is devoted to refueling in the process of using gas as fuel. It is important for a person to know the main advantages of special compressors and their efficiency. Therefore, the editors of the site "bestx.htgetrid.com/en/" have prepared for you a rating of the best compressors for refueling cylinders for 2020.

Tank types and duration of work

In order for the diver to breathe calmly under water and not experience discomfort, various cylinders are used. They come in several types, some are designed for a long dive, and the second can act as spare.

Three types of execution are on sale:

• Basic. The product is used as the main air source that allows breathing underwater. The volume of this option can reach 18 liters, but models for 9, 12, etc. are also sold. liters.
• Spare parts are also used by the diver when diving, they are used in case the main one breaks down. Thanks to him, the user will be able to surface safely and quickly. Since the device is not designed for long-term use, the volume is small and amounts to 1 liter.
• If the dive is deep, a pony tank is used with the main tank. The air capacity in this design reaches 6 liters. This value is sufficient for safe bottom exploration or long diving.

Main elements

There are four components in the tank design:

• The flask is the main element, which is a cylindrical product and is filled with air and a mixture.
• A shut-off valve is required to control the oxygen supply. There is also a safety disc here. The main purpose is to prevent the container from exploding due to the strong water pressure during deep immersion.
• An o-ring is located between the regulator and the shutoff valve. It prevents leakage and ingress of liquid.
• The shoe can be either included or sold separately. Its main function is to protect the lower part of the structure from mechanical stress.

Purpose of compressors

Today there are two popular types of cylinder compressor:

• With a standard engine that runs on fuel;
• With an electric motor.

The motor is selected based on the application. Most divers prefer electric models, as they are convenient and functional. However, this solution also has a disadvantage - dependence on electrical energy. Therefore, it is not always possible to find a suitable outlet.

Dimensional models, designed for refueling a dozen containers, are used exclusively in professional clubs that are visited by a large number of users. For infrequent use, it is better to find another option.

Compressor operation

Products capable of filling up to 100 liters per hour are more suitable for private use. Thanks to them, filling one cylinder will not take much time, which will allow you to perform the operation quickly and efficiently. There are also models in stores that can be filled with liquid nitrogen. However, they are rarely used.

Most professional and modern divers prefer to use only standard scuba tanks that are filled with compressed air. Thanks to this solution, the structure can be easily transported over long distances without the fear that the mixture may deteriorate or leak out.

When buying a cylinder, the main factors are only one thing - the manufacturer. It is best to always purchase models that have proven themselves among experienced divers and have positive reviews. Of course, the cost for such a performance may be higher, but in return a person receives a security guarantee. Moreover, most of these models are easy to use even for beginners.

Choosing the right compressor

To select equipment, you need to pay attention to a number of points.

Model differences

There are two popular options in stores - stationary and mobile. The main difference between these versions is weight and dimensions. In addition, they differ in the speed of filling the tanks.

Stationary products are installed in a certain place, since their dimensions are impressive. The price for such executions exceeds one hundred thousand rubles. The main advantage of this solution is the ability to fill a large number of cylinders. Therefore, the compressor is purchased by special companies and scuba diving schools. It makes no sense to use the equipment exclusively for personal purposes.

Portable designs are simple and suitable for beginners and professionals who practice individually. The main advantage of execution is mobility and convenient use.

Compared to the previous version, the cost of compact compressors is low. One 12 liter cylinder will fill, on average, within 30 minutes, which is a good indicator. Of course, depending on the model, the time value can be higher or lower.

Which engine is used

When choosing a compressor for refueling, it is important to determine the type of engine used. This will help you find a good and economical option. When buying, it is important to focus on the operating conditions. As you know, there are two types - electric and fuel. Each of these models has both strengths and weaknesses that are important to pay attention to.

Fuel

These designs are very popular with divers who need portable compressors. Thanks to this, a person will be able to refuel the cylinder anywhere. The only drawback of this option is that you need to constantly carry a container with fuel. In addition, fuel products are characterized by a high level of noise, and it is forbidden to use them in closed rooms, since there are exhaust gases.

Electrical

This variant has appeared recently and belongs to a new generation of compressors. The advantages of such designs:

• Low noise level compared to fuel models;
• No refueling required;
• Efficiency;
• Good performance;
• They can even be used indoors;
• Functionality.

But there is also a downside, for example:

• Requires electrical connection for operation. This is difficult to achieve in the field and has a negative impact on mobility.

Today stores sell hundreds of interesting solutions that differ not only in cost, but also in technical characteristics. When buying compressors for filling, it is important for the user to take into account some features:

• Weight;
• Dimensions;
• Operating frequency;
• Possibility of transportation;
• Convenience.

Since the diver will have to constantly drag and drop models, it is important to always pay attention to these characteristics.

Features of the gas compressor

To fill the container with propane or methane, special devices should be used. The entire refueling process is carried out using mechanical action. Such compressors are used in various fields: from home to industrial. In addition, such designs are used to supply gas to houses or apartments, its use allows you to reduce the volume of air in turbines. Automotive service also allows the use of a gas compressor, as it allows the brake hoses to be filled with air in a short time.

Modifications

In order to choose the right structures for filling containers, you should know the varieties of this device. Most popular models:

• Spiral;
• Screw products;
• Centrifugal;
• Reciprocating;
• Diagonal.

Axial and diaphragm versions can also be sold in hardware stores. Each option can be purchased at an affordable price.

Benefits of each option

In order to better understand which area a certain model is suitable for, you should know their main advantages and how they work.

Centrifugal compressors are used in industrial applications such as gas processing. Suitable for use in some chemical plants where constant work is required. In addition, some ski resorts cannot do without this option, as it creates a constant flow of artificial snow.

Diagonal models differ from centrifugal ones only in the size of the diffuser. The scope and design are the same. Therefore, choosing the right option is not difficult.

Axial compressors are designed to compress large quantities of gas. A distinctive feature of the variant: it consists of constantly rotating blades. A similar device is intended for use in gas turbines.

When repairing roads or in a complex industrial area, it is customary to use rotary mechanisms. The advantage of this option is that it is able to replace the standard engine, while maintaining power at the proper level. There is the ability to adjust the performance, this allows you to use the compressor more efficiently.

In piston designs, the compression process occurs through the operation of the piston. Like some of the previous options, they are usually used in industrial enterprises. The advantage of the models is reliability and high efficiency.

Spiral models differ in the principle of operation, which consists in compressing the gas mixture using two rotating elements. The advantages of the design include low noise level and durability of the structure.

The last popular option is diaphragm compressors. The design is an improved piston device. Only diaphragms are used instead of pistons.

What fuel is used

The main advantage of gas compressors is the ability to use a variety of fuels. Today manufacturers produce dozens of models that can work not only with natural gas, but also with nitrogen, chlorine, hydrogen, etc. At the same time, the equipment can transport fuel and fill it with various containers, including cylinders.
