NFPA Standards Series NFPA 68 for Dust Collector

 · A dust collector is a perfect place for all five of these things to happen. First of all if you have combustible dust you have fuel for a fire. Then if that dust disperses in air as it would in a dust collector it is much more explosive. Next assuming the dust collector has air inside it the fire has oxygen.

Dust Collection Systems 10 Common Questions

 · For cartridge collectors dust loadings should be kept below 2 grains/cu ft. 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.

How to Cheaply and Easily Measure Dust Collector

 · So using this information I looked at the performance curve for my dust collector. I found the 8.5" and went across to the curve and then down to the axis and it says that my flow was about 950 CFM. Doing the same thing with the 10.3" the graph shows 625 CFM. One of the popular dust collectors is the Harbor Freight 2 HP unit.

Getting Started with Dust CollectionRockler

In choosing a dust collector and designing a dust collection system it is important to remember that air volume and velocity are interrelated. As you might expect it takes a more powerful dust collector to move a large volume of air at a speed sufficient for effective dust collection than it does to move a small volume of air.
