Problems in the oil line account for about 85% of all screw compressor breakdowns. Common oil line problems include oil leaks, oil injection (oil gushing out from the inlet air valve during a power failure), excessive oil consumption, extremely low oil temperatures (leading to emulsification) and extremely high oil temperatures (leading to coking).
