If you use this style adapter on the inlet of a dust collector to allow a pair of hoses (or ducts) to be connected to the smaller ports, you will certainly have clogging if a source is chips and the "safety" bridges will block the air flow. I had them on the inlet of a small dust collector and quickly cut them out since I had clogging develop when exhausting both my jointer and my planer. My recommendation is to cut them out to insure free flow.

Of course I did, and even sanded off the sharp edge.
It is actually the merge for the two 4 inch hoses from my band saw to the 6 inch blast gate and drop.

Not worried about clogging, but working for maximum air flow. I would bet those kill 100 CFM.

That grate is there to protect the impeller from anything large. Many people connect their "dust" collection up to a floor sweep.
If something large were to get sucked into the impeller. BANG - now you destroyed the impeller fins or burned up the motor.

If you have a cyclone in front of your impeller - cut away.

another good reason to put a Thien sperator in front of your dust collector! Nothing hits my impeller......any more! :cool::cool:

If one wants a grate, they should buy a grate, not have one supplied, not in the description, for a Y .

They may not be there to act as a grate, Im thinking they may have been added to improve material flow in the tooling. Large, thin walled, injection moulded parts require very high pressures to fill the tools evenly, these would certainly help with that. Since these parts are very low volume (woodworking parts etc, compared to almost any other commodity ) This would be a cheap, easy way to improve quality and add very little cost to the tooling like an additional fill point.

Any baffle or diffuser in a Wye, Tee, or air dividing fitting is can have fins, vanes added to assist in assuring the air separates and moves equally at that fitting. They are added to prevent potential cavitation in the duct. That said, this looks like poor manufacturing.

Not poor manufacturing at all, it is "out-of-sight, out-of-mind" manufacturing! They assume the buyer won't see it so it is okay.
