Vacuum pump for a large matrix bed cnc 5 by 10 foot

[GEOFFREY]

Hi Gav, sadly my cutting area is not as big as yours (working area about 2600mmx900mm) and I bought a used pump on ebay. My pump is Reitschle (or something like that - not in the workshop to check at the moment), but it is a rotary vacuum pump. The system does not need a huge air capacity as once the vacuum is formed it is only sustaining that vacuum plus any losses caused by the cutting. If cutting small items it is safer to "tab" them as it helps maintain the vacuum and stops them disappearing into the extraction system. G.

Edit. My pump is 5hp, but I would have preferred 7 - 10hp had I been able to source one. Only have vents open to the area you are going to cut as the MDF sacrificial board will leak vacuum. G.
