Topic: Dust Collection System for Fab Lab? (Read 133 times) previous topic - next topic

thinktankgroup

Hi there!

We are opening a one-of-a-kind Fab Lab, and are looking for recommendations / advice on the best dust collection systems for the type of work that we will be doing in our shop.

BACKGROUND

- We have several different zones in our shop, including Robotics, Wood Shop, Metal Shop, CNC Shop, Chemical Storage, Paint Booth, etc.
- We will be zoning off our "dusty" work zones from our "non-dusty" zones, such as our office space, material storage, etc.
- See photo to get a better overview of our space: https://www.screencast.com/t/Bn0IPbuEL (Yellow = dust zone, Blue = no dust zone.)

QUESTIONS
- What is the best dust collection system for this kind of fab lab?
- What are you using / would you recommend for dust collection? Air purification? Fume extraction?

I would really appreciate any insights, recommendations or advice that you could share! Thanks in advance.

I'm using one of these dust collectors:
http://billpentz.com/woodworking/cyclone/
It was designed for woodworking but I actually use it on my sandblaster. Bill Pentz has published detailed instructions for making your own or you can purchase them pre-made from Clear-Vue.

For fume extraction/ventilation I use the Fantech FKD XL mixed flow inline fans. They have a good flow rate for the size and handle the higher static pressures caused by complex ducting runs or filters. In over a decade of daily use I haven't had one fail.

For particulate air filtration I use the filters recommended by Bill Pentz, both on my dust collector outlet and a separate recirculating filter in my house.

If you want a quality activated carbon filter check out the ones they sell in hydroponics gardening stores for odor control. I think that will be the lowest price you will find on that sort of filter. They are available in a range of sizes. If you live in an area where there are a lot of indoor growers you may be able to find used ones for free or cheap. You can buy replacement carbon. You may be able to renew the used activated carbon. There is a place in my local area that does this. Here's a Hackaday article about someone using one of these to filter their laser cutter exhaust:
