Industrial Pressure Washers For Tough Wash Jobs

Industrial pressure washers are powerful, high-pressure water cleaners that are perfect for blasting away loose paint or dirt. Pressure washers connect to a water supply and use an internal pump to force water through a pressure tip. Maximum flow rates vary from 2 to 5 gallons per minute, and models that produce higher flow rates typically provide less pressure. It is important that the pressure washer flow rate never exceed the water supply flow rate. Insufficient water supply will damage the internal pump that forces water through the nozzle tip to create pressure.

Pressure washers are powered by 110- or 220-volt electricity, diesel fuel or gasoline and produce operating pressures from 1,000 to 5,000 pounds per square inch. The 110-volt electric models are the most popular consumer models. These models plug into a regular household outlet for easy operation and use a cold water supply. Some of these pressure washers are hand-held models while others are mounted on a shop wall or moved around on a dolly-type cart. The hand-held or cart models are most popular with typical customers because they can be moved around outdoors to complete various jobs. Hose lengths are limited, so models which are mounted to walls must typically be used within 20 feet or less of the unit.

The high pressure tip of a pressure washer is known as the nozzle of the spray gun. The pressure of the washer is created by the pump forcing water through the tiny orifice in the nozzle. Nozzles must be sized to the specifications of the pressure washer pump to provide the best performance, and the tips are color-coded to indicate the type of spray pattern they provide. Red tips produce a high impact pencil point spray. Yellow tips are the most commonly used nozzles and produce a 15 degree fan pattern for scraping power. Green tips produce 25 degree fan sprays, which are useful for washing leaves and debris from sidewalks or curbs, and white tips produce a 40 degree washing fan for delicate work.
