VTLF 2.250
An oil-free rotary-vane pump for CNC vacuum hold-down where the required airflow and working vacuum match the table and leakage conditions.

VTLF models are commonly considered for spoilboard/nested-base tables; KVT 3.100 is identified in pod-and-rail applications. Table size alone cannot size a pump: material porosity, open zones, leakage, altitude and pressure losses all affect hold-down.
VTLF 2.400
An oil-free rotary-vane model with higher rated suction airflow than the 2.250. More free-air capacity does not by itself establish adequate holding force at the workpiece.

The highest rated suction-airflow model in this comparison. Its published vacuum rating differs from the 2.250 and 2.400, so it must not be chosen solely by a larger model number.

A dry rotary-vane pump using self-lubricating graphite-composite vanes. The manufacturer lists continuous-duty operation and a higher vacuum rating than the VTLF models compared here.

For weak hold-down, unusual noise, overheating or a trip, share the model, serial number, motor nameplate, fault history and vacuum readings. Check the table, seals, piping and filters as part of the diagnosis; a machine-side leak can resemble a pump problem.
SLAG reviews service and rebuild options around the actual unit. Inspection may include vanes, bearings, rotor/cylinder wear, filters, cooling and motor condition. Parts availability and inspection determine the repair scope; a rebuild or performance outcome is not promised before assessment.
