I just got the harbor freight dust collector. Is 27 feet to the planner too far? 4 inch pipe and it’s a straight shot. This will be at the end of the run with 4 drops in between. All drops will of course have blast gates. thanks

probably not going to provide the kind of performance you are hoping for. the HF DC is of somewhat dubious capacity.

From all the articles I have seen on how to upgrade the HF collector to make it work, my vote is take it back. From what I have seen, the cost to upgrade the HF to a working unit is about the same as buying a Jet DC with a pleated filter and vortex cone. And use 5” steel duct, 26 guage, with 4” drops.

Planer puts out more chips and dust than any other tool. Run to it should be short & sweet. Try and avoid drops and rises. Best case is to have all ports at same level. Put your blast gates at the main line instead of at each machine dust port to reduce the static load.

You can upgrade the performance of the Harbor Freight 2hp unit by adding a Wynn Environmental cartridge filter and then order a new impeller from Rikon. Then you could run a 5” trunk line and probably do ok in your setup scenario. Piping the saw dust outside is a cheaper way to upgrade the performance compared to adding a cartridge filter. The Rikon impeller upgrade is great though!

I have had a harbor freight DC for several years. It has work very well attached to a lunch box style planer.
However, I have only ever run about 15’ of hose.
I agree that the planer should be the closest tool to the DC. But try it and see what happens.
I think worst case, it won’t perform well enough. And you will need to move it closer.

Take it back. You will have about the same money in a jet as a rebuilt HF, and none of the work.

What planer do you have? My DeWalt 735 has a chip blower that does a good job of getting the chips from the planer through my trashcan lid separator without the aid of a DC.

You will want the planer the first tool the DC uses if you don’t have an internal blower. Bear in mind that a planer makes a lot of chips. You’ll be fighting with the bag system on the HF (or any other bag style collector) during any long planing session.

I can get into all the ‘hot rodding’ things on the HF DC (I recently did one), but as others have stated: You might as well pony up for a bigger system if you’ve got any sort of expansion planned.

10’ is typ max run for small DCs to heavy loads. 27’ with 4 drops & blast gates at the end is way too much static pressure esp when the runs are ceiling mounted. The lift power at the end of that run will be nil. Save $$$ by changing your layout.

I have a Harbor Freight unit and think it’s a great little unit. However, I, also, have two “four bag” units. One has cans up and the other has bags. I use them to vacuum my floor. Even with the power behind the two big beasts, I won’t run more than twenty feet of flex hose on them, and prefer shorter, when I can.

I have that HF Dust Collector, and have always used it with a 10’ hose, going straight tool to tool. Works great. It even keeps up with my 19/38 wide belt sander. On a run with anything more than 10’ of hose. I don’t give it much chance to support a planer. Planers are big dust/chip producers, and you need some pull to keep up with them usually.
