What is device wind?

Recently, the leader talked about the \"installation style\" or something like that. But what exactly does it mean by the installation style? I hope the seniors can explain it to me
Please make use of the search function; this question has already been answered in the forum before. http://bbs.hcbbs.com/viewthread.php?tid=122583 Plant air, also known as factory air or PA, is a type of utility within a plant; it refers to the compressed air used in factories. It is mainly employed for purging during startup, maintenance, or when process requirements dictate it, and is used less frequently during normal production, but more often during shutdowns and cleaning operations. Instrument air is specifically supplied to power the instrument devices of control valves, and it requires a high level of purity. Generally, factory air can be used as instrument air after dehydration and purification. The pressure is generally between 0.5 and 0.6 MPag
Thank you. I thought the device air was different from factory air. Thanks for the explanation
