dust-removal-system-design-11 The machines with the greatest airflow demands should dust removal system design 11 located nearest to the start of the run since the power of a dust collection system diminishes the farther the connected machine is from the source. If you ignore differences in price and availability, the sgstem boils down to safety. In this step, you calculate the Static Pressure SP or the resistance of your system that your dust collection unit must overcome. With two blast gates open, the air volume dropped and was insufficient to operate two big machines at once. Reuben says:.

Typical operations within a dust collection unit proceed as follows:. By connecting a dust collection system to their tools via hoses or ducting, industry professionals can help keep their facility clean and clear of excessive amounts of dust and debris.

By doing so, they benefit in the following ways:. As indicated above, dust collection systems serve an important purpose in industrial and commercial facilities. However, they must be designed and built to accommodate the unique requirements and restrictions of the facility to work effectively and efficiently.

Some of the key dust collection design considerations to keep in mind include:. Where is the dust collection system going to be located? It should be evaluated with regard to the machines and obstructions present in the facility.

The machines with the greatest airflow demands should be located nearest to the start of the run since the power of a dust collection system diminishes the farther the connected machine is from the source.

Where are the main and branch ducts going to be located? After the location of the dust collection system is decided, the next step is to determine the placement of the ducting. This factor also depends on the layout of the facility. The ductwork should be installed where it can be connected to the machines without hindering employee maneuverability.

This factor depends on several variables, including tool size, pipe run length, and number of machines connected simultaneously. Note: If a non-primary machine or pick-up is added to the system between primary machines, the size of the run is not increased.

This not 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 system with few variables. It is recommended that for larger systems a 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 prevent 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 inches larger than 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 equipment without this information. Dust suspended in air has a potential for explosion, so it 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 Dust Removal System Design Difference is computing the static pressure SP of your system to determine the size and power of your dust collection unit.

You will also 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.
