Darran, where have I said that? We were only doing a job a few weeks ago on a 3 storey townhouse with a 20ft weed just like the one in your picture and sucked it out with our 1250 machine.

[Smudger]

it was such a long waffling post perhaps it wasn't very clear, but you still required a weed hook for some reason....

Darran

[Smudger]

Out of interest why did you have a die made?

[Nick Day]

Darren, you didn't answer the question.

The gauge metal we use isn't stock so that's why we had the die made, our metal is made in Leicestershire.

[Smudger]

Your words.....
Suction was out of the question, but because of our extremely rigid, light and strong poles we were able to work the whole lot out with our downpipe fork


Why not use a stock size ?  We're your Ali tubes just swaged at one end to fit inside each other ?
Darran

[Nick Day]

Sorry to have to say this Darren, but what the hell are talking about??? Stock size is 16 gauge 1200 grammes per pole 18 gauge is 850 grammes;.  Why are they swaged at one end? Seriously?? No, your just having a laugh!!

[Smudger]

Now who's avoiding the subject ??

Ahh, well let's just put all your prickly responses to one side and try to start afresh shall we ?

From my past I worked for BAe and then several racing/f1 companies we used lots of lightweight thin wall tubing in differing grades HE15 - HE30 etc.... I was curious why you needed to extrude you own size ?

Omnivac Ali poles were an outer and inner where you slide them and clamp to get differing lengths, I was only aware that omnivac used this system, everyone else seemed to use a standard length of tube but reduced (swaged) one end so it fitted inside the tube by about 150mm then clamped it in place.

Hopefully that is clearer ??

I will leave it entirely up to you if you wish to have genuine discussions on  equipment ( by the way I think your swanneck tool has potential with further development and it's good to see new ideas ) or you can carry on in the vein of being defensive and prickly  during a thread

3000w is going to be massively better than 1250w vacuum power wise whatever way they are configured with 2inch hose.

not always , nat all 3000 watt vacs have the same suction , same as not all 1250 watt vacs do , some are more powerful for there wattage than others.

True, and it's hard work getting the info, I think there are 3 different ways to measure the vac's performance and the manufacturers/sellers use the one that best suits the spec of the vac

Exactly , they need to standardise all the tests and make manufacturers quote them all .

[the king]

well im happy with my 2400w for suction cant see a 3000w would be much beta to be honist ,as for swan neck unblocking wouldent it be easer to just have a smaller curved pipe that can just slide down the neck or a kinda flexy rubber that can be worked down the neck im toying with some iders my self as do make my own diy fitting bin thinking about this for a wile now

[JandS]

3 x 1000w or 2 x 1500w vacs connected in series or in parallel are going to be more powerful than 1 x 1250 vac assuming they are all the same spec....

[robert mitchell]

Thats the point , they are not all the same spec ........ for instance , the reason a lot of people use the 1400 watt nilfisk is because it has a lot of suction for its size , i have pulled out long sods at 3 storeys with it .......it just has a more efficient fan/design than some others .   The suction is equal to some of the 2400 watt vacs .

[robert mitchell]

Also , the wattage stated is how much power the motor draws , not its output , the output is measured in horsepower , so as with a car not all motors produce the same output even if they draw the same wattage .

There are so many variables , is the motor ballraced or just a brass bush , how many windings on the armature , how much torque it produces .......the fan has to be matched to the motor .

Its not simple at all from an engineering point of view which is why we need to have standardised tests across the board so you can compare the different machines.

[mufcglen]

has anyone got the skyvac atom, thats a 1600w and looks a nice little set up?

[Nick Day]

I would just confirm that 1600 watt with them because their website has it as 1200 watt.

[mufcglen]

confusing stuff lol, ive decided im gonna go with a 3000w vac then i can be sure its gonna be strong enough for the sake of a few hundred quid more, can i ask what make or model your 3000w vacs are nick and whats the bore of the vac outlet pipe on them?
thanks glen

[Nick Day]

Hello,

They are branded Viper but Viper is a fully owned division of Nilfisk, we have been selling them for over 3 years and they have been very reliable. They are 3000 watt with a 75 litre tank on them. We use a 2 inch hose on our machines.

[mufcglen]

cool thanks nick, getting closer to ordering one and your looking favourites at the moment lol, im very fussy when im looking at buying certain things lol but should have decided in next day or two!!
