Hi JFC As you know, I'm a little bit crazy (ok, not a little bit  and I'm almost sure that you'll not go that way but anyway, I'll show you what I did... My wife bought for the house "Electrolux", 5 filter system, variable power, 1600W... When I operated it, it was so quiet and powerfull that I went back and bought another one for the garage... I installed it on a two-part box with pre-filter and changed the hoses to 50mm (2") dia to get more airflow...and I got... Usually, I use it on "Min" power except for the table saw and router (two inlets) - "Max".      Lately, after a few experiments, I discarded the bag, plugged the inlet hole and connected an 80mm drain pipe directly from the box into the vac. At the fan inlet, I'm using a piece of the "Bag" material and on top, a piece of foam.     By adding the "Hammer", I don't have to open the box for long, long time (just to check if it's full)...With the "Hammer", I "Bang" the pre-filter a few times every now and then, and by that, keeping the pre-filter almost clean and the vac is at it's maximum performance all the time.   Regards niki |

LIDL were selling a really cheap (i.e. £30) vacuum which I bought for the van as my clean-up vacuum. For the price it's amazing value.

Niki - Like what you have done with your vac. Given me some food for thought for a similar system - I have an old Vax wet and dry so looks like I could easily utilize it like your example. Cheers  Tony |

said it before, but the trend is a decent piece of kit. i bought it instead of the metabo which is similar, but does not allow the same output on the pto. the trend is wet/dry and has a decent capacity, and for me is quite quiet. not sure how it works with larger hoses, but certainly is very decent for circular saws, and ro sanders. mind you i wondered what the white bag was, then i used it, and found it is a secondary filter and saves the main one. also very good for mdf and wall plaster  paul  |

Thank you Tony Instead of asking you if your Vax is barrel type, here is my R2D2, same method like the Electrolux but with 100 Liters barrel (from the sour cabbage guys). I use it only with table saw when I have to cut many, many boards. niki  |

I installed it on a two-part box with pre-filter and changed the hoses to 50mm (2") dia to get more airflow... Could be a problem, as this will increase the load on the motor. You probably run it much more than it would run if used for cleaning the house, and with much worse dust. I expect the bearings need to be replaced. |

Hi Roy
Yes, you are correct, a bigger opening will increase the load on the motor.
I think that the manufacturers are usually protecting themselves against "idiots" like me and what they do is, limiting the airflow (and by that the load), by limiting the outlet opening of the vac (and this one cannot be changed) so, even if I operate it with open cover, the max airflow is limited to draw not more than the rated Amperes.
But the manufacturers also want to show that the vac has such a suction that it can "lift a car" and they do it by using a smaller diameter hose.
Well, for normal house usage we need a strong vacuum pressure to clean the dust from the carpets but, for the table saw, router and alike, that are producing in 1 minute much more dust than all the house does, I think that it's better to have higher airflow that higher vacuum pressure.
If you have a look on the picture of the "R2D2", you will see the outlet at the top (I connected a 30° elbow), it's a 60mm outlet and I cannot change it. So, even if I'll use a 100mm hose, the airflow will be still limited.
I'm using this vac already 3 years and it "eats" everything, from shop dust to drywall dust and my wife is using it even for her garden.
Regards
niki

Sorry Niki, I read the posts incorrectly.
It looks as if jfc has the bearing problem. The Henry isn't a good choice for a workshop vac as the surface area of the bag is too small. It's only useful for a quickie cleanup.

and I'm almost sure that you'll not go that way but anyway, I'll show you what I did...
