Dust collector pipe biscardi | posted in general discussion on august 21, 2002 0519am i was all set up to hang 4 inch pvc in my new shop to run the dust.
Perhaps your cfmcubic feet per minute is not enough from your dust collector.I have used metal 4 in my first shop and 4 thin walled pvcmuch cheaper in my second.In my current studio i have two collectorsone on each side of my shop so i dont have pipe running across the ceiling.
Vs.Plastic duct below.The next step is to size your system.See designing your system on pages 4144.Metal vs.Plastic duct plastic pipe or pvc pipe is unsuitable for dust collection for three reasons first, plastic pipe ttings are not offered in.
Reducers are for reducing the size of a branch or trunk line when connecting a smaller pipe or hose.Main diameters are available in 4 to 20 inches and reduced diameters are available in 3 to 18 inches.Note fittingtofitting joints use outside couplers, while pipetopipe joints use inside couplers.
The harbor freight dust collector may be a good value but it isnt a very powerful machine.Replacing the fan will only provide modest improvement.The problem you will have using over sized pipe is air velocity.You are running the risk of having dust settle inside the pipe due to slow air movement.
Understanding the process, localizing dust collection, and minimizing collector size all help simplify installation of collectors and their associated equipment.In addition, a review of the collectors installation and operation manual before installation starts can identify tools andor unique items necessary for a smooth installation.
At pipe joints, leave slack in the wire or install bayonet connectors radio shack has them to facilitate opening the system in case of a clog.Run a ground wire along each branch, and splice each into the main wire.Connect the ground wires conductor to the dust collectors metal frame or housing.
Next, decide on what kind of hookups you are going to use flexible hose, pvc pipe or metal duct.To see what size and type of collector would best suit a oneman shop, i gathered a sampling of machines, from 1hp singlestage units to 2hp twostage collectors, including one cyclone delta 112 hp single stage, dust boy 2 hp two stage, jet.
When this occurs, select the pipe size that is the closest to the required diameter.Continue on to the remaining machines per the example above, until your main trunk is equivalent in diameter to the size of the collector inlet.For example, consider a system where the main trunk line is 6 in diameter representing 615 cfm.When connecting to.
