Dust Collection System Layout

Determine diameter and cfm of main duct 5.

Dust collection system layout.

In reality proper pipe sizing can get complicated and depends on many variables. Many dust collection systems suffer due to poor ductwork designs. Designing your dust collection system there are five simple steps to designing an effective and efficient dust collection system. Determine duct velocity fpm 3.

Draw a floor plan of your shop 2. Figure system resistance sp static pressure. The things that increase static pressure in dust collection include smaller ducts longer distances bends in the pipe and flexible tubing so we will focus our efforts in minimizing those things that materially increase static pressure in our systems. Air and wood particles moving through the dust collection system quickly build up static electricity charges in any nonconductive hose or piping hose or piping not made of metal.

For more on central dust collection see wood magazine issue 43 june 1991 ppg. There is a large amount of misinformation about what the proper size pipe is to run. Tool size air requirements length of pipe run required number of machines running at one time etc. Dust collection design can be complicated here are a few simply steps to laying out an effective and efficient dust collection system.

Dust collection duct design is a complex science and i am going to intentionally. The first phase is sizing your duct work for adequate volume and velocity of flow for the type of dust you will be creating. There are two phases to designing your dust collection system.
