The first elements of the pneumatic system, located at the beginning, are the air preparation devices. They are necessary to prepare the working medium necessary for the proper functioning of the pneumatic elements.
Cleaning is filtration that reduces solid particles, condensation and oil.
The reducing element (reducer) serves to regulate the pressure so that it reaches the required level. Lubricators are used to introduce oil mist into purified air to lubricate pneumatic tools.
By sucking in air from the room, solid particles enter the compressed air through the compressor.
Oil particles enter the tank through the compressor lubrication system and, together with water (which is sucked in with the air), form the so-called condensate.
The compressed air is filtered inside the filter, which removes solid particles. The filter has a cleaning accuracy class. The filter can also remove oil and water, i.e. condensate, through the rotary movement of the air and filter cartridges.
The filter consists of a body with inlet and outlet holes. The air enters the filter in the direction of the arrow and is directed downwards, where there is a system that rotates the air and uses centrifugal force to precipitate the condensate.
As not all oil particles are removed by the pre-filter, the remaining amount can be removed using an oil separator.
There are industries in which the air must be extremely oil-free, such as medicine, painting, pharmaceuticals and the food industry. It is also not good for industrial automation.
To obtain the best air for use, the air must pass through a pre-filter where it is cleaned of particles and oil. So it can be a fine filter and a carbon filter, which leads to purity class I. ISO 8573-1 standards
Water drainage must be done through filters on the first level, but the rest must be done with a dehumidifier that physically removes the water. This is the value that ensures that the air is perfectly prepared for operation.
Loss of water in the pneumatic system leads to many failures and malfunctions, as well as corrosion.
To reduce pressure in any pneumatic system, pressure reducers must be used. These valves are included in the pressure control group and can be adjusted manually.
Its function is to maintain the pressure at a constant level, even if the inlet pressure increases and the flow rate changes.
lubrication
The pneumatic system is lubricated via an air preparation station or lubricators.
To ensure the proper functioning of the device, it must be lubricated with oil. Air lubrication is also necessary for pneumatic tools such as grinders, screwdrivers, drills and hammers.
The oiled compressed air enters the working system as oil mist and reaches, for example, compressed air tools and other moving parts that need to be lubricated. This helps prevent failures and malfunctions and can at the same time extend the life of the receiver or system while being corrosion resistant.
Air handling components may include other additional devices required for use in the pneumatic system.
These can be manually operated shut-off valves, soft-start valves or check valves.
These elements lead to an expansion of the functionality of the air treatment plant. Air handling units can consist of two-piece units, i.e. a filter, a reducer and a lubricator, but are also available as three-piece units consisting of a reducer, a filter and a lubricator.
