Vacuum pumps from Becker are the industry standard and used with any floor model CWI CNC Router when using vacuum suction. For smaller 4×4 and 4×8 CNC machines we recommend the Becker KVT 3.14 and for larger production CNC machines, we recommend the more powerful Becker VLTF 2.25. For our Bench-Top CNCs, we recommend the STORM vacuum pump from Black Box Vacuum Solutions.
