Westinghouse WPro8500 is an industrial portable generator designed for industrial use. The robust WPro8500 is easy to move around at the job site and at home with the never go flat 10 inch tires and a foam grip handle.

Safety features such as overload prevention and low-oil shutoff give the users peace of mind. It is designed for rugged industrial applications and can also be used as an emergency source of power during a grid power failure. Sound attenuation features, heavy-duty performance, and low THD make it a number one choice for those looking for a low-cost reliable standby portable generator.

Westinghouse WPro8500 is safe for electronics that have a microprocessor and is transfer switch ready. The 13.5 HP 457cc Westinghouse OHV 4-Stroke engine features low idle control that manages the speed of the engine to tally with the load. The steel frame makes it long-lasting.

It generates 8,500 running watts and 11,500 peak watts, which are ample to run an AC; a sump pump, an electric stove, coffee maker, microwave, dishwasher, and other household appliances. Users can charge mobile phones and tablets using the 5 built-in USB charging ports.

At the job site, you can use it for powering an air compressor, belt sander, bench grinder, circular saw, table saw, rotary hammer, demolition hammer, industrial motor, capacitor start induction run (4 hp), computers, portable heaters, and air conditioners. OSHA requires GFCI protection for job-site power sources and this unit has just that.

Westinghouse WPro8500 runs for 17.5 hours on 6.6 gallons of fuel on a 25% load. The price is very affordable and financing options are available.

For added safety, all 120V and 240V outlets have rubber covers. The professional grade WPro8500 comes with a battery, battery charger, key fob, oil, funnel, tool kit, manual and quick start guide. Along with the residential and commercial warranties, buyers also get lifetime technical support.
