EL-AV ELAD15INV EL+ Series 15 HP iPM Variable-Speed Rotary Screw Air Compressor (460V/3-Phase)

EL-AV EL+ Series rotary screw air compressors deliver continuous-duty compressed air at the lowest energy cost per CFM in their class. Every EL+ machine ships standard with an iPM (interior permanent-magnet) TEFC motor rated IP54 driven by a fully integrated variable-frequency drive, ASME & UL approved pressure components, and built-in VNC remote connectivity for status monitoring from any device on your network.

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: permanent-magnet rotor for IE5-class efficiency and constant torque from minimum to maximum RPM.
• Integrated VFD: soft-start eliminates inrush; no star-delta starter required; no unloaded losses.
• TEFC IP54: totally enclosed fan-cooled — safe for dusty machine shops, woodworking, food packaging, and outdoor sheds.
• VNC connectivity included: view the controller from any PC or tablet on the network.
• ASME & UL components: compliant pressure vessels and electrical for U.S. installations.
