Trying to find a vacuum pump

[Kevin1964]

I am building a vacuum forming table and need some advise on what really to use for the suction side of it...I have tried a domestic hoover which does suck quite well but i think i need something a lot more powerfull than that..Question...Has anybody on here got a garden vac because i would like to know if they are better in terms of suction

Any other ideas would be most welcome

What about reversing a leaf blower?

If you have a compressed air supply, you could use a venturi type vacuum generator.

I used these at work a few years ago to create vacuum in a system to draw fluid through a filter. Company name is Secomak, though they supply this through a sub company... http://www.beck-air.com/PneuPower/tabid/82/Default.aspx

The unit (on this page) is a "pneu power type B" can create -1.0 bar vacuum (the particular application I used this for was a 205 litre stainless stainless steel drum of which it could evacuate 205 litres to -0.6 bar vacuum in around 8 seconds using a 7 bar main compressed air pressure.

Worth a thought if you want something with a bit of poke.

Thanks for the info ddavidson..I don't have access to a compressor at the moment so that idea is out of the window for now Going to try out drifts idea if i can get a decent unit cheap enough..Most of the high power leaf blowers/suckers tend to be petrol models which won't work for me as its being used indoors..Electric me thinks but are they as powerfull as the petrol versions ??

Inlet manifolds on car petrol engines have a vacuum to work the servo

Obviously you would need the engine running to get a vacuum but it should do the job, if you are feeling really creative, convert a gas bottle into a vacuum chamber, put a valve on it, hook it up to your inlet manifold and create your vacuum then shut off the valve till you need it
