Topic tags/keywords: question dust collector 30 micron 5 micron

I’m having a small battle with right now over a dust collector I ordered.

The specs on the site say that this unit ships with two 5 micron bags.
However, the Delta user’s manual that is online says it ships with two 30 micron bags.

When I emailed Amazon about this they replied and said, “I’m sorry, but we can’t check the physical details of an item for you…”!!! I wouldn’t call this a ‘physical detail’ but a specification of the item – similar to saying an item takes D batteries when it takes C size – it affects the performance of the item in a big way.

I’m somewhat venting and somewhat posing a question here… I looked online and see that sawdust particles can be as small as 30 micron, if that is the case these should do fine. However I’ve been told by a few, much more experienced, woodworkers that I need to go to a <5 micron bag.

Can anyone shed some light on this? I got a great deal and free shipping on the item, however if I need to buy new bags there may have been less expensive alternatives.

Before i hurt my back in the FDNY, i also had my own air filtration company. I got into it because my son has severe asthma. The lower the micron number the better the filtration. One problem with that is you will use more replacement filters. sawdust can range in micron size depending on if you are cutting wood or fine sanding. If you want send me a message and i’ll give you my phone number so i can explain more.

I would call Delta to find out if that model can handle the smaller micron bag. It may put to much strain on the motor.

Check with Delta and see if they supply this model with 5 micron bags. I think you’ll find it’s a typo on Amazon’s part.

I’ve read we need to go down to less than 1 micron, because the smaller particles are like asbestos. So, along with the dust collection system, I have a filtration system that goes down to 1 micron and I wear a respirator that goes below. Good Luck. If you need the brand names and models get back to me and I will get them for you.

I agree the 1 micron bag is the way to go.

Without a doubt you should be in the 5 micron range but 1 to 2 microns is much better for your health. Thirty microns lets dangerous ultrafine particles escape which are then taken into the lungs where they lodge and cannot be removed.

Wood Magazine did a review on dust collectors in issue 182.

If Amazon sells 5 micron bags for your collector, they’ll need to send you a couple to make up for their advertising mistake. I wouldn’t get off the phone until that happens.

To make a long story somewhat shorter. I had a bit of a headache with getting the people at Amazon to understand my issue, they actually tried to send me a whole new dust collector – a costly solution for them to ship it to me and me to ship it back to them, especially when that wouldn’t solve the issue. Finally, I got someone that understood the problem and tried to resolve it. Amazon doesn’t carry the 5-micron bags but other sites do – about $53.00 is the best price I’ve found. Since they didn’t carry the item they offered me a 20% refund of my purchase. I paid $190.36 for the AP400 dust collector, no sales tax to ship to GA, and they had a free shippibg promo going – My net price for the collector – $150.36. I still have to get the 5-micron bags but not bad at all in my opinion. Once Amazon understood my issue they worked quickly to resolve it the best they could.

Great hearing that Amazon was able to resolve your concern once they were able to hear and understand your concern. The 5 micron vs 30 micron bag is a pretty signifcant difference in filtering.
