The Alkota 4405HNS is a portable or stationary gas-engine hot water pressure washer rated at 4 GPM and 4000 PSI. Power comes from a Honda GX630 engine with electric start. The burner runs on diesel or kerosene and is rated at 355,000 BTU. It measures 48 x 31.25 x 41 in (L x W x H) and weighs 700 lbs.
The GED-EN Extra Narrow Series is a self-contained hot water machine on a narrow frame: 22.25 in wide as a stationary skid and 31.25 in with the portable wheel kit. A gas engine with electric start drives the pump and a 12 V oil-fired burner heats the water, so the 4405HNS needs only a water supply. The narrow frame leaves room on a trailer, truck bed or van floor and fits through tight doorways.
