While most devices can be supplied directly from a compressor, the pressure delivered is not uniform. Pressure fluctuations occur in line with the operating frequency of the pistons or rotors, resulting in uneven operation of the equipment.
Air receivers are installed to eliminate this issue, allowing gas to be stored at a specified pressure. When the pressure inside the receiver drops below the preset value, the automatic control system activates the compressor to restore the required pressure. A correctly selected air receiver can help extend the service life of the compressor by reducing the number of start/stop cycles and consequently lowering electricity consumption.
In compressed air systems with multiple pressure take-off points, it is often impossible to maintain the required operating parameters of the medium directly from the compressor alone. In such cases, an effective solution is the use of air receivers as buffer tanks, i.e. compressed air storage vessels. Proper distribution and grouping of pressure take-off points, together with the correct selection of buffer receivers, enables independent operation at individual workstations without causing disturbances or pressure losses in other sections of the system.
