Keep in mind I am a real novice to the world of Wood Working, but not a novice to common sense and home repair.


I just purchased this unit and am at a bit of a loss, I really expected this DC to have the suction power to pull a penny off the floor, does not seem to be the case here.

My observations are from just setting the unit up with nothing attached to it yet, no pipe ducts or tools.

After posting in another thread about the noise level in regard to the DC having a lot of air flow noise. I have a Shop Vac connected to a Dust Deputy for my Orbital Sander which has worked fine for me.

For a test I connected the 3" hose that connects to the Dust Deputy to one side of the Y connector on the HF DC, using aluminum foil as a reducer as I have none at the moment. From the Dust Deputy to the Sander there is about 15' of 2" hose. The suction was almost nothing, the bags were about 3/4 inflated until I disconnected the Dust Deputy, I am at a loss.

How is it possible to have so much apparent airflow under no load to almost nothing when connected to the Deputy? The HF DC has the Y connector to connect 2 machines at one time, as is it seems one machine could not be used with the what seem like a complete lack of suction.

I thought the HF DC would at least double the suction compared to the Shop Vac...

If I place my hand over one side of the Y it just does not seem like there is the amount of suction I was expecting, Help!

Sorry if I am missing something so simple but things just are not adding up. Any advice or help would be appreciated.
