The selection of an air compressor depends on:
- Use of compress air, but also according to its functional principle
- According to how it works: motorization, power, capacity, etc.
There are two different mechanisms between compressors: screw compressors and piston compressors. This classification exists for both professional compressors and those for private use.
THE SCREW COMPRESSOR: COMMERCIAL BUT EXPENSIVE
The screw compressor is the compressor system most frequently use by the general public. The air is compress by rotating the two rotors of a screw. On the one hand, the compressor sucks in air through the rotation of the screw, on the other hand, the air is pump out under pressure. Due to their small size, the screw compressors are easier to handle, which is especially true for portable or cordless compressors (example: inflating car tires). They’re also some of the most expensive on the market. The high price can lead a buyer to purchase a use compressor at a lower price.
PISTON COMPRESSOR: ESPECIALLY IN INDUSTRY, ESPECIALLY FOR GASES
Driven by a motor, the pistons move back and forth through cylinders which are provide with shut-off valves. This movement compresses the air. Piston compressors are mainly use in industry and can permanently compress gases. (ABAC compressors for example).
The type of supply to the engine influences the functioning and the possibility of using compressors. A distinction is made between two types of motor: electrical or thermal.
ELECTRIC COMPRESSOR: THE SIMPLEST
The cheapest model, which is easiest to use, is the electric compressor. However, it cannot be use on construction sites. This is because it must be continuously connect to a power grid.
The electric compressor can be use, for example, for the following work:
- Sandblasting: sandblasting gun
- Painting work: airbrush and paint spray gun
- Inflation: air nozzle via a quick connector
THERMAL COMPRESSOR: THE MODEL FOR PROFESSIONALS
The thermal compressor is primarily intend for professional use. It is power by fuel: gasoline or diesel. It is therefore more expensive than an electric compressor. But it is far more powerful. Since it does not require a power connection for operation, it can be use more mobile.
SPECIAL COMPRESSORS: WHISPER- AND OIL-FREE COMPRESSORS
Compressors also have several disadvantages. Therefore, certain compressors have been develope to make the devices better and more convenient to use.
- Whisper compressor: does not disturb the neighbors and is easy on the user’s ears.
- Oil-free compressor: reduces waste of oil and usage costs
A compress air tank can become a dangerous item because it is under high pressure. Fortunately, several systems ensure optimal safety: manometer, which is connect to a safety valve via a T-piece, drain valve, etc.
Application of standard industry compressors?
For Standard Industrie International, compressors are an important part of cleaning processes and the removal of deposits in silos, hoppers, filters, etc. Compress air is use as follows:
- in the containers of the AIRCHOC® air cannons of our Airchoc series
- for our machines for cleaning silos and hoppers Gironet , and our drilling machines Powernet
- also in our extraction systems (cleaning of filters) .
As a rule, our customers already have a compressor for the entire factory hall. But it is also possible to determine the require output for new installations and to set up new compress air networks, for example to cover the compres air requirements of our air cannons.
The connection between the compressor and the tank is made via a rigid pipe made of steel or stainless steel, the diameter of which can vary depending on the require output.
