The compressed air preparation unit (CPU) provides cleaning, drying, regulation of outlet pressure, and, if necessary, enriching the air stream with the necessary components. The reliability and service life of all elements of the pneumatic system depend on the quality of air preparation.
Main components of the air preparation unit
All components of the BPV are combined in a common housing. Their list depends on the area of application of the module. The block may include:
- Filter — cleans the air stream from mechanical particles. Can be installed separately or as an element of oil and moisture separators.
- Moisture separator. Water particles are absorbed by a granular adsorber, which is regularly removed from moisture by back-blowing with air.
- Oil separator. It is used in pneumatic system modules in which the presence of oil in the air stream is unacceptable.
- Lubricator. Its function is to saturate the compressed air with oil particles. Lubricators are necessary in air treatment units of pneumatic systems servicing pneumatic tools.
- Gearbox. Regulates the pressure of the air stream and is installed at the outlet of the BPV.
Basic and additional functions of the air preparation unit for pneumatic tools and pneumatic systems for other purposes
The main tasks of the BPV:
- cleaning the air stream from dust and larger mechanical particles;
- removal of moisture, that is, dehumidification of air;
- depending on the type of pneumatic system — cleaning the air stream from oil or, conversely, saturating it with oils necessary to lubricate the rubbing particles of the pneumatic tool;
- outlet pressure regulation.
Optionally, air treatment modules can perform the following functions:
- emergency release of pressure in the pneumatic system in the event of problems;
- divide the air flow into several circuits;
- heat the air at low ambient temperatures.
How to buy the right air preparation unit in accordance with a specific technical task
When choosing a suitable BPV, the decisive factor is the list of necessary functions, which determines the configuration of the module. Examples:
- blocks of pneumatic systems that supply pneumatic tools — filter, water separator, lubricator and gearbox;
- BPV of automotive equipment — filter, moisture and oil separators, gearbox;
- industrial pneumatic systems — the composition of the unit depends on the requirements for the composition of the air stream in each specific case.
