Long Continuous Duty Without Three-Phase Power
No three-phase supply on site, but the vacuum must run for long continuous shifts?
Turbine (side-channel blower) motors are built for long continuous operation — unlike carbon-brush motors that need rest breaks. Selected turbine models up to 3 kW can be configured for 220V single-phase supply with capacitor assistance, so a missing three-phase line no longer forces you into short-duty machines.
Recommended Models
EHTD22 / EHTD30 in the 220V configuration, or the EHTS-X series (EHTS17X / EHTS22X / EHTS30X) in 220V versions.

IMPORTANT NOTES
Key Reminders
01 Models of 4 kW and above cannot be built for 220V single-phase — a three-phase supply is required.
02 Do not treat single-phase carbon-brush machines as long continuous-duty units.
03 Three-phase versions ship with aviation plugs; 220V versions come with an 8 m power cord. International voltages can be customized.
