Airblo vacuum pumps

[Buffalo Creek Sugar Camp]

Does anybody know who manufactures the pump itself on the Airblo vacuum pump skids? They are a rotary vane type pump. I didn't know if Airblo make them themselves or not, but thought maybe another manufacturer makes them.

Alot of the Airablo units have Wallenstein pumps.
