Topic tags/keywords: dust collector laguna pflux p flux p-flux question

Considering buying this machine. I have read the 175 or so posts of this thread. Does anyone have an update on the crossbar modification? I should it shipping with all pflux3 units now? Has it solved the problem of the bin under the filter filling too quickly?t

I got mine in May and it did not come with a cross bar and does not separate dust at all. There is as much in the filter bin as there is in the drum. Secondly it is loud at 94dB. Not the 76dB that they claimed.

Also, here is a video of the lack of separation: https://flic.kr/p/V1UGUC

Mark have you gotten any response from Laguna on this? For a $$$ machine designed specifically to separate dust i think you have quite a case to make.

Interested to hear because I am considering one of these unites.

Mark C,
Are you saying that in collecting that little amount in the drum, that you saw that much material pass through to the cleanout below the filter???

If so, that is dreadful performance. I haven’t seen that much in the cleanout of my 2hp Tempest after collecting 300 gallons of sawdust. Actually there is nothing in the cleanout.

I agree with you about your video… material should not stay in suspension in the cyclone. If it stays suspended too long, some will eventually make its way to the cleanout.

Marc, thanks for sharing your experience. I must ask. Are you sure that you don’t have an air leak in the dust bin? It is really hard to believe they would put a machine out with that poor performance?

Humph,

Your question suggests that you are interested in separation efficiency. In that regard I suspect that the Laguna Flux series of cyclone collectors generally offer less efficient separation of course versus fine dust; crossbars or not.

My understanding of cyclone separation efficiency is that the velocity of the dust swirling in the cyclone vortex and the length of time dust spends in the cyclone are important factors that impact separation efficiency. A 3hp dust collector, with adequate air flow and a properly designed vortex initiator should move the dust at a fairly high velocity and which are feature I presume are incorporated in the Laguna Flux 3. However, since the Laguna Flux models offer short cyclone funnels, the length of time the dust is in the cyclone is less than that of cyclone models offering a longer cyclone funnel. But then, if height restrictions preclude a longer cyclone funnel, then less efficient separation is the compromise.

Have your say...
