Sound Reduction Engineering for Super Quiet Running— Significantly reduces environmental impact from noise to a minimum. Robin Subaru further enhances sound reduction of inverter technology by fully enclosing units inside double-wall, foam-filled sound attenuating panels of rigid, high-impact resin to reduce both high frequency and low frequency sound.   Decibel Level Testing Performed in Anechoic Chamber

Sound Attenuating Panels Reduce Noise

Compact Engineering Allows Sound Enclosure— Advanced cooling technology employs a single integrated cooling fan for both engine & alternator to reduce bulk & weight and facilitate sound absorbing enclosure. Cooling air flow is enhanced & noise is minimized. Large, soft-tone mufflers specifically designed for each engine further enhance quiet operation.

Robin Subaru Puts Easy Portability in Portable Generators—
When it comes to high power output with easy to carry, easy to handle, and easy to use features, Robin Subaru offers a model line with all the features you need. An inverter converts independent DC current into standard household AC current. New technology now allows converters to be of high efficiency in conjunction with a generator, resulting in a number of advantages:

Compact & Lightweight—inverter’s greater efficiency allows reduction in overall size & weight by about one-third vs. similar class generators. A lone operator can easily carry, set up, and run smaller models. Easy-grip frame design, plus wheels on some models, maximize ease of handling throughout the range of larger models.

High Quality Electrical Output—portable inverter type generators output smooth power, comparable to public utility sources. Ideal for powering computers & equipment sensitive to voltage surges

Very Low Noise—significantly quieter operation due to inverter’s fast, efficient switching of current waveform. The engine need not work as hard to generate high levels of electrical power. Unique soundproof panels, vibration control & soft-tone muffler further reduce noise.

Low Fuel Consumption—inverter technology, combined with more sophisticated throttle control, automatically adjusts engine speed to electrical load, reducing fuel use by about 20% vs. similar class generators

Meets Strictest Environmental Regulations—U.S. Phase II and CARB Tier II

All Robin Gasoline Generators Have One Thing in Common— Quality!
Designed for long running construction and rental applications, Robin Subaru builds the entire engine and generator together as one high quality unit, unlike some other manufacturers who build only one or the other major component.

All Models Offer Heavy-Duty Standard Features:
