Check Valves

For vacuum only setups, the blower system will need to have an appropri-

ately sized check valve on the inlet side of the blower.

If the blower is to be operated in a pressure mode, a check valve will need 

to be used on both the ballast air system and the intake side of the blower.  

Note that the ballast circuit normally draws air into the blower.

Use the same size check valve as the hose used to plumb the system.

Primary Shutoff

A primary shutoff is to be used with the blower as a first line of defense to 

prevent liquid from entering the blower.  It is critical that an appropriately 

sized primary shut off is used.  Contact NVE for assistance with selecting the 

shutoff.

Secondary Shutoff/Moisture Trap

The secondary shutoff or Moisture Trap should also be appropriately sized 

for the air flow application.  Contact NVE for assistance with selecting the 

shutoff.

Bag House

Bag houses are typically used in systems where dry material is being 

pumped.  Specification of a proper bag house depends on the frequency 

and type of dry material being pumped.  Consult the factory for assistance in 

selecting a bag house.
