The description of the y-piece part no 452898 states
"for D 50/D 36/D 27, for connection of two dust extraction hoses, with blanking plug,
for extractors that admit hazardous dust, simultaneous operation is not permitted,"
I'm not sure what is meant by "simultaneous operation is not permitted".
Does it mean that one branch of the Y must always be closed off?
