I have a room length 12 m * width 4 m * highest 3 m and a machine inlet air flow 10 m3 /min. Then how can I calculate the dust collector capacity or cfm for the dust collector and how can I say that dust collector needs 60 filter bags with dimensions 3 m length * 12.5 dia if its capacity 10000m3/hr? Please answer me. Thanks a lot...

  • I'm not exactly sure what you're asking here. Are you trying to figure out what filter bags to use with your dust collector? Or are you trying to choose which dust collector you need? What do you mean by "60 filter bags"? Is that the particle size in microns? If so that seems pretty coarse. I think 1-5 microns is more typical. I guess if your bag is outside the shop that would be fine. It seems that if your dust collector has 10m^3/min (600m^3/hr) air flow your filter bag doesn't need 10,000 m^3/hr capacity. – SaSSafraS1232 Dec 13 '18 at 23:53
  • Also, the room size doesn't really seem relevant to this question, unless you're actually asking about an air filter, not a dust collector. For choosing a dust collector you just need to consider what machinery you're using it with and what diameter and how long your ducts will be. – SaSSafraS1232 Dec 13 '18 at 23:55
  • In case you don't know, a "dust collector" hooks up to individual machines (or sometimes multiple machines, via various kinds of duct) and collects the dust as that machine generates it. An "air filter" sucks air in from the room it's installed in, and pushes it right back out again, filtering it in the process. Both technically collect dust, but via very different methods. They compliment each other. An air filter might catch whatever a dust collector missed. – Katie Kilian Dec 18 '18 at 4:46
