What is the maximum pressure of standard compressed air?

Standard pressure range for conventional compressed air systems

In industrial and commercial applications, the operating pressure of conventional compressed air equipment is typically set at0.7 to 1.0 MPa (MPa)Between, which converts to approximately 7 to 10 bar (bar) or 100 to 145 pounds per square inch (psi). This range can meet the requirements of the vast majority of pneumatic tools, production line control valves, and basic manufacturing equipment.

Key factors affecting the system’s maximum air pressure

• Terminal Device Requirements:Actuators, blowers, and drying equipment on different production lines have specific requirements for supply air pressure; blindly increasing the pressure will not improve efficiency and may instead accelerate seal degradation or cause loss of control over actuator operation.
• Pipeline pressure drop loss:Frictional resistance occurs as gas flows through pipes; the longer the distance and the smaller the pipe diameter, the more pronounced the pressure drop. During system design, an appropriate margin should be provided at the source to ensure that the terminal points achieve the minimum pressure required for operation.
• Energy Efficiency and Cost-Effectiveness:For every 0. increase in compressor discharge pressure. 1 MPa Power consumption typically increases in a stepwise manner. Selecting a lower operating pressure, while satisfying process requirements, is a crucial step in optimizing overall energy consumption.

The Upper Limit of Conventional Systems and Safety Standards

Although special designs or tandem configurations can achieve high-pressure outputs of several tens of megapascals, the rated maximum discharge pressures of conventional industrial screw and reciprocating air compressors are mostly concentrated around1.3 to 1.5 MPa (13至15 bar)Configurations outside this range typically fall under the management of high-pressure special equipment, imposing stricter requirements on tank materials, welding procedures, and safety accessories. In actual operation and maintenance, pressure regulation should be performed in accordance with the allowable working pressure indicated on the equipment nameplate, and pressure gauges, relief valves, and the safety factor of gas storage tanks should be periodically verified to ensure the pipeline network remains stable over the long term.
