  • Designing an Efficient Dust Collection System Spiral

    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.

  • The Impact of Duct Diameter on CFM Oneida Air Systems

    By using the same exact dust collector and simply running the correct diameter piping we were able to get twice the amount of CFM to our tool. Had one actually set up the system with 4" pipe they would have very poor pickup at the planer and they would be wasting most of the system's energy to friction loss. October 6, 2011.

  • The Importance of Sizing Ductwork for Dust Collection

    The dust collector is the main ingredient in getting cleaner air for your shop, but if you can’t get the dirty air into the collector efficiently, you risk high energy usage, degraded collector performance, and unsafe conditions in the plant.

    The Calculator that Don Beale and I setup shares most of the values you need to dig pretty hard to find in order to use this calculator and uses default units typical for dust collection instead of trying to cover flow rates for a wide range of other alternatives.

  • How to calculate dust collection horse power per feed and

    Now let's look at some contenders for an entry-level dust collection system. A 1hp Grizzly dust collector rated at [email protected] produces 500 CFM/235 l/s and 2.76"/7 mbar of static pressure. As you can see from the CFM figures above, under ideal conditions this dust collector should be able to capture most of the dust from most tools except larger

  • Dust Collector Calculations & Sizing AST Engineering Inc.

    The dust collector performance ratings should show that at your given Static Pressure, the CFM it will provide. The first step in designing your system is to draw a floor plan of your shop area including the following: Location of dust producing machines, indicate size & location of dust pick-ups on each machine. Remember Machines with the


    XYZ-brand dust collector, with an 20 in. dia output fitting, is rated at 800 CFM maximum and 500 CFM working (under load). Its collector is a 55 gal drum, so all air exits through the top bag. Look for a bag that will handle 1200 to 1600 CFM maximum, or 750 to 1000 CFM working (under load) output. From these charts we find the bag should be 20

  • Dust Collection Systems: 10 Common Questions

    Apr 17, 2019· To calculate loading, take the dust being sent into the collector (lb/hr) and multiply it by 7000 grains/lb. You then calculate the total system air volume per hour. Finally, divide the grains per hour by the total airflow in an hour to get grains/cu ft.

  • Maximizing Dust Collection System Efficiency Compressed

    Dust collector systems are vital to many plant operations, particularly with respect to meeting both indoor and outdoor air quality standards. They are also often used to collect income-producing product. At the heart of a pulse-jet type dust collector is the proper installation and availability of compressed air.

  • Air-to-Cloth Ratio: What Is It, And Why Does It Matter?

    It is calculated by dividing the amount of airflow (CFM) by the amount of filter media in the dust collector. For example: A dust collector with airflow of 4,000 CFM and 2,000 square feet of filter media has an air-to-cloth ratio of 2:1. A dust collector with 2,000 CFM and 2,000 square feet of filter media has an air-to-cloth ratio of 1:1.

Using grid stone makes t his stone more accurate. Be sure to indicate the exact location of each dust port. Indicate the CFM requirements for each dust port.

  • What Is Differential Pressure? Donaldson Industrial Dust

    A more gradual increase in differential pressure drop may be a result of the additional resistance accumulated dust on the filters is placing on airflow going through the dust collector. You can use the reading of this resistance to determine the relative condition of the filters as the dust builds up on the filters and to initiate cleaning of

  • Dust Collector Sizing: What Size Do You Need?
