Screw compressors

During the safety valve operation (when the compressed air is blown out
through it) loud noise is generated. When any maintenance operations are
carried out, you must wear hearing protection and safety clothes protecting
against air stream.
You are not allowed to operate the machine in the system with the faulty
safety valve. The faulty valve must be immediately replaced with a new one
after the machine stopping and unloading.
