CORMAC, INC. Construction Equipment

Rugged and powerful generators for the most demanding jobsites

Designed for construction rental and other demanding applications, these high performance, portable generators deliver unmatched tool starting and voltage regulation in a rugged, compact package. Built the Wacker Neuson way, with heavy-duty frames and premium components to provide long, trouble-free operation even in abusive environments. Ideal for powering high starting amperage tools such as compressors, grinders, fusion welders, saws, pressure washers as well as all of your Wacker Neuson electric- powered pumps, breakers, drills, concrete vibrators, etc.

Best in class tool starting and voltage regulation due to unique step-start generator technology with AVR (automatic voltage regulation) and separate excitation winding.
Unique GFCI (neutral bonded to ground) sensor system eliminates common GFI outlet failures while offering personal protection on all receptacles including 240 Volt. Meets the latest NEC and OSHA jobsite standards.
Full wrap-around frame with dual cross-member support, high impact polyethylene fuel tank and heavy duty shock-mounting combine to provide outstanding impact protection.
A super quiet muffler allows for versatile operation.
Unique auto-idle control with time delay system automatically reduces the engine to a low speed reducing fuel consumption, noise and wear.
The folding central lifting eye and integrated wheel kit make these compact generators easy to transport and store.
Full power switch for maximum 120V power output or 120V/240V power.
Available with the high performance Wacker Neuson OHC engine (on GP2600 and GP4000) or Honda OHV engine, both feature low oil shutdown.
