Laguna P|Flux 3hp HEPA Cyclone Dust Collector

Item #
48% of 100

The p|flux:3 offers ''smart'' technology, power and a HEPA filter that removes all but the very smallest dust particles. The horizontal chute maximizes airflow and improves the volume of air moved (measured in cubic feet per minute, or CFM), allowing the 3hp, 220v motor to deliver as much as 2,817 CFM. The HEPA filter removes 99.2% of particles down to .4 micron in size, and internal sensors trigger LED indicators when the 46-gal. drum is full and when the filter needs cleaning. Swing-away doors offer easy access to the filter, and the doors are lined with acoustic foam to reduce noise. The unit comes with a high-frequency remote control.

An ingenious lift system raises the drum into position, and a connector on the back of the drum automatically hooks up to a pipe in the cyclone to create low pressure in bottom of the drum; this holds down the plastic bag to prevent its being sucked up into the cone during use. If the p|flux is used without a bag, the system can be shut off. The drum lowers easily onto its wheels for emptying.

Good Unit
While I agree that it took more than 6 hours to complete the install, I found the instructions pretty clear and all of the parts were in the shipment. I had a couple of questions for the Laguna staff. They returned calls promptly and were very helpful.

Definitely recommend this machine.

Woodworking Experience:
add on dust deflector for cyclone
One of the first to buy this unit. Same issue with separation. But read about simple add on dust deflector to bolt on existing bolts at bottom of cyclone. 10 minutes labor. Sent from Laguna for free. Noticed immediate difference as fine dust no longer being pulled up into cyclone when turned on. Will need to use for awhile to see if it helps in the long run

Woodworking Experience:
Good unit, issues others have experienced are easily solveable
I’ve now had my unit over a year, and I was one of the first people out there to take the plunge and get one. I have totally experienced the same issues that many people have complained about, but all of them so far have easy fixes. Read on...

1. From factory, the separation is an issue. This is likely due to the shorter form factor cyclone drum which is a problem with most of this type (in this instance, length does indeed matter). Laguna makes and now ships these with a deflector bar that is installed between the cyclone drum and the collection bin, and that greatly improves the cyclonic air column movement thereby improving separation. One thing that drives me crazy is that people complain about having dust in the filter. YOU ARE SUPPOSED TO HAVE DUST IN THE FILTER. That means the filter is doing its job and stopping it from blowing back out into the shop. Now, you shouldn’t have large chips in their, but fine dust: absolutely.

2. Go bagless. The separation on this thing works SOOOOO much better without a bag, because the negative pressure inlet valve has a tendency to get clogged and/or you rely on that collection bin being *perfectly, 100 airtight* for it to work properly. Not an easy scenario to get right, since the user has to build the drum and do the caulking to seal in any leaks. Simply don’t use a bag, take off the inlet valve, and plug the hole with the provided plug. Voila. Night and day difference.

3. For your own sake, STOP REDUCING AT THE COLLECTOR. I know they provide reducer coupling with the unit, but there to my mind there is no single thing that will decrease air movement (CFM) than reducing at the machine. If you have to, reduce to 6” ducting from the collector, and than 4” at your actual machines. You’re going to thank me!

Laguna all in all did not knock this one out of the park. It shouldn’t have left their factory with the obvious (though easily fixed) engineering issues. However, it’s a powerful machine and when these things have been taken into consideration, it’s still the best short column cyclone that I’ve used, and it really can move a lot of air. Suction for days.

Serious design flaw in separation
As has been said by others, about 25% of the collected dust ends up in the HEPA filter section which is difficult to remove and clean. I'm using a wide belt sander and I can only get 10-5 passes on a 4" wide board before the HEPA light is on. I would have to clean out the HEPA filter probably 8 times before I would fill the much more convenient to use dust hopper in the front.

The HEPA issue can make for and even worse problem - if the HEPA filter gets loaded up, pressure builds and the rubber bung pops out of the bottom of the HEPA dust basket and turns the whole unit into a 2000 cfm dust cannon. I was in the back of my shop when this happened and it looked like a solid rocket engine test. It's been a day and I am still cleaning my shop from this disaster. This thing has a control unit and sensors - why not shut the unit down instead letting the pressure build to the point that you blast dust everywhere.

There is not point in HEPA filtration if the unit is not able to move air most of the time. Plus, going in and manually cleaning the inside of the filter with a vacuum after every 15min of sanding sort of defeats the purpose, no?

Woodworking Experience:
Separation sucks
The cyclone separation is horrible. Like others here, I am very disappointed in Laguna. I have several of their products. I cannot understand why they allow this.

Sucks but does not separate
I purchased this unit excited that I was getting an upgrade. It turned out it was a mistake. While it was definitely more powerful than my old single stage dust collector, the dust separation was non-existent. It literally filled the post-filter collection bin with barely any in the bin that the dust was supposed to be collected in. It just didn't separate the dust from the airflow. I spent many calls with Laguna support, who were very helpful, but no resolution. I ended up changing it for a Clear Cue which works so much better.

Woodworking Experience:
This dust collector is junk
I bought the PFlux3 for my shop. It has adequate cfm's but the cyclone separation is terrible. It gets the larger shavings ok, but the fine dust goes into the HEPA filter and clogs it regularly. We end up cleaning out the filter assembly almost as regularly as the chip container. The Chip container is mad out of cheap sheet metal and the wheels bent the bottom metal and the unit does not roll any more. I have an older Laguna 3 hp dust collector at home and use it regularly and do not need to clean out the filter assembly very much. Bottom line I will be selling this unit and getting something else.

Needed to upgrade my 1.5hp unit. Wanted to go with a 5hp unit but was restricted by ceiling height. This seems to be a good value based on several months of research. Actually had a Clearvue Cyclone just about ordered. Was going to have to cut holes in my ceiling... this will help avoid some wife aggro.

Is it better to use the three inputs or branch of one larger port?
Marv V on Sep 18, 2016
BEST ANSWER: If you can afford it you should ALWAYS go with the larger diameter ductwork (8" in this case) to the furthest machine and then branch down with say 6" to the blast gates and then reduce down to the diameter (5" or 4") of the machines dust port with flex hose. The name of the game is to move the largest VOLUME of air as you can before restricting the airflow with smaller diameter hoses.
What is the noise decibel ?
Chris M on Sep 28, 2016
BEST ANSWER: 76 dB p flux 3
My question is for Laguna concerning the Automatic Cleaning System that they offer for the C/FLUX System. Why is it NOT offered for the P/FLUX machines? Premium Dust Collectors should have a Premium Cleaning System. Is it because it might damage the HEPA filter?
Tim H on Dec 5, 2016
BEST ANSWER: you cannot clean HEPA, coating is too sensitive
Does the Laguna P|Flux 3hp HEPA Cyclone Dust Collector really draw 22 amps when running on 220 V? Also does it have automatic filter cleaning?
Gary A on Oct 19, 2016
BEST ANSWER: Gary, My directions say the unit runs at 17amps. It requires a 30amp circuit because it probably draws over 20 amps at start up and levels off to 17 amps while running.
No there is no self cleaning mechanism included. Directions say to blow a out filter once in a while with an air compressor.
Can these units be vented to the outside?
Chad S on Apr 21, 2017
BEST ANSWER: If you means placing the unit outside in an enclosure and ducting it inside to your woodworking machines, yes. That would help with the noise as well. Otherwise there is no other venting. Sawdust is captured in the can below the cyclon with a very small amount ending up in the can below the HEPA filter.
I would like to get a second remote for my new P/flux. Where can I find one, and how much do they cost?
John on Dec 2, 2017
BEST ANSWER: I believe they cost around $60.00 you can purchase by e mailing customer service:
How will this arrive at my house (multiple boxes?) How much assembly is involved?
Timothy W on Dec 1, 2016
BEST ANSWER: 1 box. about 4 hours assembly
is it better to buy the hepa unit or the regular cyclone one?
kevin g on Jul 4, 2018
BEST ANSWER: Neither. Buy an Onida instead. My product came scratched Missing parts and cables (j box) that were to short. They sent out cables that I could have made. The housing rubs the motor fan blades. When I plane material through my minimax Combo, half the material ends up in the filter. Big let down!
What plug should I use? Nema 6-20 or 6-30? My outlet is a 6-20 but it looks like the motor uses 30amps.
Y G on Jan 31, 2018
BEST ANSWER: You need to use a 6-30 for an outlet.
Is this machine prewired with a plug, or will an electrician need to direct wire it to a 30 amp circuit? IF it has a plug please provide specific info on the plug so appropriate outlet can be wired.
P R on Oct 26, 2016
BEST ANSWER: No plug .Check 4bolts on motor make sure that there tight.Elec junction may not be able to mount on brace of legs because wires need to be lengthened,loosen nuts and make longer.Vac works well but sure would be better in a sound proof room as I did, it is loud.
After reading the reviews I have serious doubt about the separation. One reviewer mentioned an added deflector bar. Is this a new fix that is applied to all new units sold?
Jeff G on Jul 1, 2018
BEST ANSWER: I am not 100% sure they are shipping with the unit now but the response I received from Alex in customer support was that they were going to be shipping with the piece.
We mix cement in enclosures. Can any of your systems be used for collection of silica dusts?
neil n on Oct 10, 2017
BEST ANSWER: This machine seems to be more intended for wood dust, that said it is HEPA. I think there are probably better long term machines out there that are more specific for silica dust. Good luck.
