Part of my system includes a wireless, automatic system that turns the dust collector ON and OFF as various woodworking machines are turned ON and OFF. Click here for a tour and video on the iVAC Pro system.  Most workshop dust collection systems need rigid pipe somewhere, but no matter how much or how little you’ve got, flex hose is the best way to make final connections to machines. It makes precise machine position on the floor non-critical, and it helps isolate vibration from resonating in any metal collection pipes.  Spiral metal pipe is my personal favourite for wood shop ducts. Thick walls make it exceptionally strong, and well able to solidly anchor screws connecting duct joints. Dust Collection System InformationDust collection design can be complicated, here are a few simply steps to laying out an effective and efficient dust collection system. We have simplified the dust collection system design process for smaller shops, it is important to know federal, state and localities have codes and regulations enforced by AHJ (Authorities. A Simple Dust Collector. This video is about A Simple Dust Collector made out of a wheelie bin. My Thien Dust Collector. Thien Dust Separator - tablesaw test. Grounding PVC Dust Collection Systems. Oneida Dust Sentry Warns When Workshop Du. Designing an effective dust collection system takes planning and a little know-how. In this article, we'll introduce the most important considerations in designing a dust control strategy that really works. Is it really necessary? For many hobbyists and owners of small professional shops, an adequate dust collection system falls in the "luxury item" category – with so many other tools to buy, it can languish at the bottom of the priority list for a long time. Here Woodworking Dust Collection System Design Zoom are a few reasons to start taking dust seriously right now.  Dust produced in a wood shop can be divided into two general categories: large dust particles, chips and shavings, and fine wood dust. By far, the largest volume of debris created in most wood shops falls into the category of large-particle dust, chips and shavings.

Remember Me. There are two phases to wood shop dust collection system design your dust collection system: The first phase is sizing your duct work for adequate volume and velocity of flow for the type of dust you will be creating; and the second phase is computing the static pressure SP of your system to determine the size and power of your dust collection unit.

Prior to making your calculations, diagram the floor plan of your shop to scale on graph paper. Wood shop dust collection system design the size and location of each machine, and the location of its dust port desivn outlet; the floor to joist dimension; the location of the dust collecting unit; and the most efficient fewest number of turns or bends path for routing your duct lines. This is also a good time to start your take-off list of duct components for your system.

Below this minimum FPM, particles will begin to settle out of the air stream, forming clogs—especially in vertical wood shop dust collection system design. Table see below shows the minimum FPM that Spiral Manufacturing recommends for several types of dust in branch and main runs. From the Table determine the velocity FPM of your system for the type of dust that will be produced. For the purpose of the following examples assume woodworking dust.

Determine the diameter of each branch line. You can use the diameter of a factory installed collar or port, or consult the manufacturer. Convert metric ports to the nearest inch. Convert rectangular ports to the equivalent round diameter.

Record any reducers or rectangular to round transitions on your take off list. Using Tabledetermine the CFM requirement of each branch. Remember the FPM for wood dust in branch lines wood shop dust collection system design Identify your woid or high-use machines. These are the machines that operate simultaneously on a frequent basis. The objective here is to define your heaviest use scenario so you can size your system to meet udst.

Including infrequently used machines and floor pickups in your calculations will only result in an over-designed system that will cost more to purchase and to operate. At this point, all of your branch lines are sized, and you have a list of all components required for your branch lines.

Now you are ready to size the main trunk line. Begin with the primary machine that is furthest from where you will place the dust Table Saw Primary Radial Arm Saw Dust collecting unit. Wood shop dust collection system design If a non-primary machine woof pick-up is added to the system between primary machines, the size of the run is deskgn increased.

This wood shop dust collection system design only assures adequate air flow but also anticipates a future upgrade in machine size. In this step, you calculate the Static Pressure SP or the resistance of your system that your dust collection unit must overcome. To do this you total the Static Pressures of the following system component groups:.

Calculate the SP of all branches to determine which has the greatest SP. Only the branch with the greatest SP or resistance is added to the total. You can use the charts on pages to assist in your calculations. You now have the information you need to specify your dust collector. The above example is for a small sustem with few variables. It is recommended that for larger systems colleftion professional engineer be consulted to assure that the system is properly designed and sized.

If the dust collector is located in a separate enclosure, it is essential to provide a source of make-up air to the shop to wood shop dust collection system design a down draft through the flue of the heating system. If this is not done, carbon monoxide poisoning could result. If a return duct is necessary from the dust collector, it should be sized two sesign larger than Dust Collection Systems For Woodworking Shops Pdf the main duct entrance and its SP loss added into your calculations.

Some dust collection units may not include fan curve information that shows CFM or Static Pressure variables. We do not recommend procuring collector dessign without this information. Dust suspended in air has a potential for explosion, so dfsign is recommended that you ground all of your duct runs, including flex-hose. If your system has areas where long slivers of material could possibly hang-up and cause a clog, install a clean-out near that area.

Many types of dust, including many woods are toxic, so take special care to choose a filtering system that will provide optimal safety. Designing an Efficient Dust Collection System. Designing Your Dust Collection System There are two phases to designing your dust collection system: The first phase is sizing your duct work for adequate volume and velocity of flow for the type of dust you will be creating; and the second phase is computing the static pressure SP of your system to determine the size and power of your dust collection unit.

You will wood shop dust collection system design need to familiarize yourself with the following concepts: CFM Cubic Feet per Minute is the volume of air moved per minute. FPM Feet per Minute is the velocity of the airstream. Step 1 From the Table determine the velocity FPM of your system for the type of dust that will be produced.

Step 5 Now you are ready to size the main trunk line. Figure Step 6 In this step, you calculate the Static Pressure SP or the resistance of your system that your dust collection unit must overcome. To do this you total the Static Pressures of the following system component groups: 1 The branch line with the greatest SP or resistance see Figure Summing the SP loss for the system, we have: Highest loss branch: 5.

Additional Considerations and Recommendations The above example is for a small system with few variables. Blast gates should be installed on all branch lines to maintain system balance. High Pressure Products. Table Velocity for Types of Dust.
