Industrial Vacuum Specifications

Dynamic Type Vacuum Producers:
HSI Multi-Stage Centrifugal Exhausters 

The exhausters feature cast aluminum one piece impellers that are both statically and dynamically balanced to ensure absolute mechanical integrity.  Minimal clearances are maintained to achieve the highest possible mechanical efficiency.

A set of impellers are securely locked and keyed to a hot rolled steel shaft to comprise a rotor.  Intermediate sections are firmly bound together between the inlet and the outlet by strong steel rods to comprise the housing.  The rotor is the operative component and the only moving part in the machine.

The rotor is supported at each end by out-board bearings in cast housings that dissipate heat and provide for easy maintenance.  Seals are non-contact, non-wearing labyrinth type, machined to remarkably close tolerances.

Lubrication is available in grease or oil formats, and normally continuous operation requires a lubrication schedule of just minutes every two to three months.  These units are exceptionally tolerant of neglect!

Special Features

• Continuous Duty Operation

• Low Maintenance Requirements  Bearings only require maintenance every 1500 to 2000 operating hours.

• Mechanically Efficient  Compared to units with fabricated impellers, cast impellers achieve 65 - 72% mechanical efficiency.

• Exceptional Service Life  Many exhausters are still running 40 years after being put into service.  The rugged cast iron housing and cast impellers stand up to tough operating conditions
