Using my back up machine at present, which has vacs in series. The problem is that today's carpet was not of the type where the wand 'locked on' very hard, so the effect of the lift never came into play.
Doesn't this limit the usefulness of vacs in series? Paralell seem to work fine on any carpet. ???
-
If it locked on hard then there would be no airflow so no difference.
-
I was a staunch beleiver in series VAC motors as all the science seems to point to it being more effective. I recently swapped my motors over to parallel just to see the difference and I have to say they are better! The carpet drys noticeably quicker and working is faster. I can't explain it but it is...
From what I can see lift is important to a point then airflow is key... I don't think I will go back to a series set up now.

You can have lift w/o airflow but you can't have usable airflow w/o lift surely

I agree. It is a balance between the two that is important.
Full lift occurs at 0 airflow, maximum airflow occurs at 0 lift so its what happens in between that does the work.

Hi Robin, out of curiosity, did you just get a parralell manifold from matt? And did you replace your sd motor with a 2nd hd or are you using an sd/hd parralell pair?
-
I'm using the original HD plus SD motors. I am thinking of changing the SD to a HD as this should increase both the lift and cfm of the machine however this will put the whole setup over 13 amps on one cord which is a worry. However I do have a standard machine with 3 x 1200w motors running on 1 cord and it works with no probs so I might just give it a go. I know John Martin does it ok.
I did just use the original manifold. It is just a a standard manifold for parallel vacs with an extra mounting and blanking price to allow a series set up. I just removed the extra bits.
-
I might give mine a try next time im bored. in parallel you have the benefit of using the cleansmart booster if you so wished, probably give close to 300cfms with similar lift.
-
Can series vacs be switched to paralell? If so what would need to be done?
-
It depends on the machine. To be a parallel set up both motors need to be mounted in a way that they both independently draw air from the waste tank. On a series set up one motor draws the air from the waste tank and the other draws the air from the exhaust of the first. Some machines will be easier to swap around than others. What do you have?
-
It's an old Masterclean Rhino. One of the vacs has been upgraded to an Electro 5.7 but the other is an original, probably 1200w vac. If I could get another electtro 5.7 in there and run them paralell this would be very nice.
-
Is your Rhino tank one of the strengthened ones? if not I would be wary of increasing the power too much as it may split.
-
If you are going from series to parllel it will have less vacuum so will be ok with the existing tank.
You should get more flow with a lower vacuum reading.

I used Ninjas for nearly ten years and used a booster motor that fastened to the back of the machine and although it apeared more powerfull, I noticed a big difference when I bought my first Scorpion which was also a tripple 5.7 motor set up but in parallel
the carpets dried much quicker

It will be possible to swap over the motors but not easy. I have never seen inside a rhino but if its anything like a ninja it will be difficult but not impossible.

Have you ever tried just a two motor parallel machine? is there much of a difference between two and three vacs, I have been so impressed with the difference in my set up I am considering adding an extra vac.

Hi Robin, you inspired me to change mine over so i did, and i used it on thursday and i gotta say It cleans much quicker-it was an already clean carpet and only 6months old though.
Interested to see how it cuts into a minger. As you know , i also have a jag, when i got the airflex i noticed it was alot slower wanding, still very nice to use and does a great job but no where near as fast as the jag was.
Switching to parrallell has now narrowed the gap imo, there is still less wand whistle at 50ft but to be fair i never go over 75ft and i feel this will be great out to that range.
I think 3 of the 1500w electros would make for a great setup.

At the time of buying a new Scorpion I also bought a new Extracta Exell, but I was not impressed at the power difference,
the fact the exell only had one port imo made a huge difference

I think the Exracta was unnecessarily restricted by its plumbing. I have noticed since going parallel the importance of 2" hose as well. Its another thing I would never change back to now....

Great.. Lewis. I think 3 Electros is my next move....

Plenty of room on the manifold for a third, or you could perhaps get a pre made turbo manifold And run it with an inline switch. the booster pod would be another option but the 6.6 would have lower lift then some of the electros, depends which you fitted.
I see cleansmart now offer the choice of 2 high powered electro 5.7s in place of the lamb 6.6s on the airflex storm (if i read it correctly)

To make it possible it looks like you will need an two extra lengths of vac hose and a Y connector. If you disconnect the exhaust from the first "metal" motor and direct that out of the machine using the same hose this will then free up the intake of the second "plastic" motor. You will then need to attach a piece of vacuum hose to the intake and then connect that to the the other hose which goes to the intake of the first motor using a Y connector. You can then connect the Y connector to the waste tank using another short length of vac hose. You will be able to get a Y connector from Altec.
Some things which will improve performance a lot will be replacing the plastic motor with a newer electro motor, John Kelly has these in stock and they seem to be the best price at the moment. Using all 2" hose for all the plumbing. and changing your machine inlet for a 2" inlet. If you feel really adventurous adding an extra vacuum stack to the waste tank will also improve the performance however that may be easier said than done.
I hope that all makes sense.

I just had a look and that looks quite interesting. I think I will make my machine in to an "Electro Storm" With an Electro booster. That should give somewhere in the region of 330cfm and (11hg) 150" water lift.
