EDCO ER Series Vacuum Pumps: T12F Body

A T-base allows either one, two, or three ER venturis to be internally connected in parallel to obtain a greater combined vacuum flow rate. 

For total vacuum flow, read the vacuum flow rate at the desired vacuum level from the ER performance graph then multiply by the number of venturis installed in the T-Base. Normally, only the larger ER venturis would be selected for this pump.

The ER series T-base offers greater vacuum flow in the same foot print as the Chip Pump T-base.
