The new Extracta apparently has twin 8.4's.

Can you run it from the van?

[Glynn]

I suppose you can, if the vans in the room being cleaned.

Glynn  ,  did you say you have both a storm and an Enforcer  ... two very different vac systems  , which do rate the most for performance or is there much in it  ..
I know they don't compare to your  TM   !   

[Glynn]

The Enforcer has the edge but they both feel like the Titan with the waste tank lid off.

 Thats really interesting , thanks  .   

 The series 5.7 Electros  out performing the parallel 6.6  .

 Would be good to have booster with another two of the same vacs in series to plug into the enforcer in parallel giving an airflow boost .

with regards to micro splitters its the lack of good marketing about them i don't understand, again its like the TM issue its a cleaners choice and not really about customers benefits. with many people suffering from asthma, soap allergies and perfume allergies are just two groups that would benefits.

I don't think I have ever seen Soap free marketing in a big way. it might just get a line on a page but not in any USP way

[Russ Chadd]

My Alltec Express has exactly the same motors fitted as the Enforcer and its a beast... same performance at a fraction of the size, use it for those smaller jobs such as single rooms, arm chair and car upholstery... also dead handy when you are faced with stairs and no elevator.

   Dont think you'll find any more 8.4 machines  ...    It looks really good in series for sure
   Only issue is perhaps the cost (about £300 ! )  the weight and fitting size in some cases .

    Ken harris measures 14.5HG and 123cfm for the series 6.6  .... the sandia optimizer also confirms 14.5 in series showing that its fairly low lift motor ...
Much better with the Electro setup used by Ashbys and others now  ... more lift and almost as much CFM   17HG and 117cfm .  And  using the HD+SD motors they can easily put them on one cord with the pump ...  allowing cord two for heat

So the 8.4 won't show significant difference compared to the electros ?

Nice video sells the system very well.

Well , i was saying that the HD+SD Electro setup would be better than a series 6.6 setup ans it has more lift and can go on one cord .

Two 8.4s would be better  ...  certainly than the electro HD+SD 
but it might not be hugely better than two HD electros  ...    not too sure if you could put either pair on one cord ... well im sure you can but don't know if manufactures will   ...  both would be good in parallel also im sure .

[V_Purcell]

You would be just as well to fit Lamb 4 stage vacuums, I forget what the lift was now, but it was a lot better than the 3 stage by far
But they command a hefty price. But would fit without much modifications.

Airflow is really low with the four stages   , although it would be interesting to try combining it with other motors .

[V_Purcell]

Which would you prefer air flow or water lift, as you can always increase airflow.

Which would you prefer air flow or water lift, as you can always increase airflow.

I know they will be related at the wand  ... but generally both are desirable .
That why a motor like the the Electro  ( would be 146" and 117cfm )  would be more desirable than you four stage ( 180" and 60cfm ) 
What have you in mind for increasing airflow while maintaining lift .

Easily done with a quad vac in series /parallel .

[V_Purcell]

Air flow is related to the size of your vacuum pipe in the dump tank and the pipe that come off your vacuums, if you change from 1-1/2 to 2" you increase your your air flow, but decrease the inches of water lift, but you must use 2" vacuum hose and a 2" wand. Every orifice must be increased, even the top of the vacuum motor.

Yes .. but over the last few years 2" machine plumbing has become the norm on High end portables  ...  so its taken as a given than when discussing vacuum systems the machine have been optimized for airflow  .  Also Motor figures quoted are generally 2" for cfm and zero for lift . 
An airflow optimized machine still wont give you more airflow than the chosen motor or configuration of motors used can produce .

[V_Purcell]

And then you get guys who by an 1-1/2 tube wand, instead of getting a 2" straight through wand, which will decrease the air flow, but increase the water lift.

By 'increase the lift ' do you mean increase the vacuum rise time ?  lift would also also be determined by what the motors can produce . Put a lift gauge on a machine with 2" plumbing and to the same machine with 1 1/2 .. no difference in ultimate lift imo .
