■
As drain fluid or dirt in the supply pressure line may block the fixed orifice or cause misoperation,
fit a 5[micro]m or finer air filter (such as an SSS Mini-Set filter) and use a dryer or similar to
ensure a clean air supply.
■Using a lubricator on the supply side may cause a blockage in the fixed orifice or nozzle. Never use
a lubricator with this I/P converter.
