Vacuum Pump Selection Data

• Very similar to the Condensate  Pumps

• Voltage- Needs to be exact example

• 230-3-60 not 230/460-3-60

• Simplex or Duplex

• Load - Typical units include EDR, BTU, Pound /HR

• Back Pressure -  Usually gravity return but can discharge into a pressurized return main.  Need Static+ lift + distance and size  pipe.

• CFM is sized per ASHRAE we will take care of that

Mandatory Equipment

• Tank

• Pump 

• Float Switch Starts and Stops the Pump Simplex Units or a Mechanically  Alternating float Switch (Mechanical Alternator)  for Duplex Units.
