Ibuprofen belongs to a class of medications called nonsteroidal anti-inflammatory drugs (NSAIDs) that reduce pain and inflammation.
The torr (symbol: Torr) is a non-SI unit of pressure with the ratio of 760 to 1 standard atmosphere, chosen to be roughly equal to the fluid pressure exerted by a millimeter of mercury, i.e., a pressure of 1 Torr is approximately equal to one millimeter of mercury.
While recharging the system with refrigerant, the 134A manifold gauge pressure should be monitored so the proper amount of refrigerant is used. Two different pressure gauges can be used, either low or high. For a low pressure gauge, a reading of 25 pounds per square inch (psi)to 40 psi is optimum.
