Hi,
I'm going to first time buy a vacuum pump and make a small vacuum table DIY. I have not enough knowledge to choose the pump, but by some googling I found this one on ebay:
called:
2.5 CFM 1 Stage Rotary Vane Deep Vacuum Pump Refrigerant AC Air Condition HVAC

Link:
2 5 CFM 1 Stage Rotary Vane Deep Vacuum Pump Refrigerant AC Air Condition HVAC | eBay

My use case is to have it holding corian dupont for small lithophane works (say, maximum 20cm x 30cm).

Is this pump enough powerfull for the job I described please?
