Rule of Thumb Pump Sizing for CNC Router Tables
As a general industry standard, when matching the right pump to the table size, 5.5 CFM per square foot of surface area is required for nested base or spoil board tables. Pod and Rail tables utilize small suction cups and, therefore, require much less flow and usually use just one size pump.
| Table Size | Square Feet | CFM | Becker Pump | Becker Duplex System | CFM |
| 4’ x 8’ | 32 | 176 | VTLF 2.250 | DS 250 W | 352 |
| 5’ x 10’ | 50 | 275 | VTLF 2.400 | DS 250 W | 352 |
| 5’ x 12’ | 60 | 330 | VTLF 2.500 | DS 250 W | 352 |
| 5’ x 20’ | 100 | 550 | – | DS 500 W | 706 |
| Pod and Rail | 12 | 66 | KVT 3.100 | – | – |
