I have one 1hp dust collecter and will be receiving another one. My question is can I hook them up to the same main 45 gallon seprator. This will then be using the main trunk that I am all ready using.

If you run them at the same time, you could have problems.

I think it might actually work assuming they have similar performance curves. Another assumption is that the main trunk feeds into the separator which then would need to have the suction line split into 2 lines, one going to each DC blower. Assuming the DC inlets are 4” you would need a 6” trunk. I’m not sure what this kind of set up would really gain over a reasonably sized DC system. Are you running multiple pieces of equipment at the same time? If so, you might be better off hooking a DC to a couple of pieces of equipment and then hooking the other one to a couple of other pieces of equipment. You could still have a separator in front of each of the DC’s if you keep the pipe runs short and limit the elbows and hose.

I guess the real question is why do you need that much air flow? You can get more air flow but it won’t appreciably change the vacuum in the system.

I think Stumpy Nubs has a video with a simliar experiment using 2 of the HF 2hp units on a single cylcone. Should be on his youtube channel.

I think you might be better served by using one on the separator and the other for one specific tool that makes sense in your shop to leave hooked up. I think that even with some fabrication to straighten the airflow you won’t get double the performance from having two.
I’ve been wrong before though, by all means test it out!

Have your say...
