Methods For Removing Moisture And Oil From Compressed-air Lines In Paint Facilities

摘要

Moisture in compressed-air lines causes a serious problem for application of paint and powder-coating finishes. The most obvious of the problems is product spoilage as a result of a defective finish caused by spotting or "fish-eyes." Metal that has been sandblasted is susceptible to rusting. Rust and scale can also form in the compressed air piping and clog nozzles or affect the surface of the finished product. If air lines are exposed to extremely cold weather, freezing of the water in those lines can easily occur, blocking the path of the compressed air. Condensation and possible freezing can also occur when compressed-air equipment is exhausted rapidly, especially through small nozzles or orifices.
