Dear All
Thanks for the positive feedback re our input to the forum, time as always against us so I will not be a frequent contributor but will be only too happy to reply to any specific e mails sent to us, this is not me being evasive just not enough hours in the day.
Right trying to cover most of the bases from the post following mine:-
Ivan, yep once the main filter is occluded then you start to have problems in that airflow is reduced - recommendation - use an interceptor tank to drop out the volume and reduce this problem ideally with a cyclonic lid to take more of the fine dust out at the first stage.
As I said in my first post all 2.5" machines now have cyclonic entry with NVT feature as standard this dramatically extends the time before the main filter needs cleaning, don't forget that this is what the machine is designed to do, stop that stuff being pumped back into the air.
Pawnking belive me a cyclone is not easy to design, one that works well anyway, for the best part of 2 years we have played around with a prototype add on for Camvac users and it is at this time with a rather well know wood turner based in Norwich. All of the dimensions are inextricably linked to each other change 1 and change them all if you see what I mean, anybody can put a rough 80% collector together but to do the right thing of 90 - 95% is not easy without some serious CFD software like Mr Dyson. I will never knock competitors machines imported or otherwise, the Trend machine has it's place as do most. The Camvac machines are available dependent on model in 1, 2 and 3 motor configurations, each motor unit is an industrial application unit made in Europe and provides 54 litres per sec or 111 cfm with a vacuum level (water lift) of 2080mm. With what you are looking at you I would recommend a 2 motor the critical unit is as always the planner and you do not say what width it is?? maybe you could e mail me this and any other questions you have separately. As for being a Newbie with amateur questions forget it, my guess is there are others out there that would ask the same questions but their ego won't let them ! ! !
Ivan - re your second post, our combination of airflow and water lift provide us with the answer to most hobby, light trade and mid size workshop applications, a separate division of our company goes up to 25hp 3 phase units with high pressure low volume (same as the Camvac concept) the real key is airflow, just because a machine has a 4" port doesn't mean it is the right size in fact most machines including my own bandsaw I have blocked off all of the manufacturer ports and created my own as theirs were the wrong size and in the wrong place.
As for pricing well that's not easy, whilst we might want everything for the lowest ever price we as manufacturers have our overheads, so even as you are working in your workshop we have people back here working on the next models, working on improvements, working on cost reductions without sacrificing quality and working on keeping the units made in the UK. Over the last year we have seen steel rocket and copper and plastic just go ballistic average across the board 30 - 40% (the far east are just sucking the raw materials in so fast the prices go crazy) we have worked hard by better buying and slicker manufacturing to keep cost down.
Barry - your 3hp extractor, is I guess a twin sock unit with 1 stage filter with filtration from 5 to 10 microns and as soon as you get filter blockage or you try to reduce the inlet dia you will loose up to 80% suction, we have brought the machines in and done the tests, they are dust pumps, wear a mask! ! !
Noise - all Camvacs have exhaust ports, thes can be used for blowing or a pipe of similar dia can be attatched without restriction and the warm air and noise can be ducted outside the workshop, it is a very effective route to take dB levels @ 2 meters with the outlet at eye level are :-
1 motor 68
2 motor 75.1
3 motor 75.6
Hope this helps, any specific questions just drop me an e mail at
