EL-AV ELFD100INV EL+ Series 100 HP iPM Variable-Speed Rotary Screw Air Compressor (460V/3-Phase)

EL-AV EL+ Series rotary screw air compressors use an iPM TEFC (IP54) motor and VFD control. The US price list specifies ASME & UL approved components and VNC connectivity.

The integrated VFD turns motor speed up and down to exactly match plant demand — no unloaded run-time, no blow-off, no wasted kilowatts. Compared with a fixed-speed load/unload screw of the same nameplate horsepower, an EL+ inverter machine typically saves 25 – 35% on electricity across a real-world duty cycle while holding system pressure to within ±1 PSI.

Why EL+ vs. a Conventional Rotary Screw

• iPM motor: high-efficiency permanent magnet motor.
• Integrated VFD: soft-start eliminates inrush; no star-delta starter required; no unloaded losses.
• Drive motor: iPM TEFC (IP54).
• VNC connectivity included.
• ASME & UL approved components.
