These pumps are usually offered as single-stage or dual-stage models. The single-stage models are typically used with 1.5” - 2.5” diameter lines and provide an operating vacuum level of 7-8” Hg.
The dual stage side channel blower models are use with 1.5 – 3” diameter lines and provide 10-11” Hg operating vacuum.
It is important to include a vacuum breaker valve which allows pump run-on after loading is complete to extend side channel blower life and ensure instant vacuum on request.
A cartridge inlet filter is typically used to trap carryover fines.
These pumps are known for their quiet operation.
