High pressure washers are mechanical cleaning systems that primarily use water sprayed at accelerated pressures, allowing it to penetrate and remove surface materials more effectively than manual washing. Depending on the pressure applied, this type of cleaning system is ideal for removing dirt, mud, corrosion, grease, paint, mould, grime and other surface contaminants.
Uses Of High Pressure Washers
Cleaning: Heightened pressure water streams perform well in car washes, outdoor cleaning projects involving buildings, roads and other concrete structures, and are also ideal for graffiti removal.
Surface preparation: Plants, facilities and equipment ordinarily require adequate surface preparation by cleaning and removing thoroughly all surface contaminants prior to the application of protective coatings and other corrosion protection solutions. These washers for industrial uses are effective for surface preparation.
Coating removal: Replacing existing paint, corrosive substances and old protective coatings is an important first step in corrosion protection systems. Washing at an increased pressure is the preferred technique for coating removal because it thoroughly cleans without harming healthy substrate materials.
Hydro demolition: Repair of damaged concrete requires concrete removal, surface preparation and cleaning of reinforced steel. Pressured water streams can remove damaged concrete safely and leave a rough surface that allows it to bond with the new material. Water used in the concrete removal process also suppresses dust.

A high pressure cleaner system will have a motor, high pressure pump, supply and working hoses, fittings, a jetting or control gun and a nozzle.
Motor: Typically a diesel or electric engine, the motor generates the power to drive the pressure pump of the washer. Gas powered engines are more flexible and can be used for outdoor environments. Electric models plug into outlets are quiet and produce no exhaust, ideally suited for indoor applications. Electric pressure washers can deliver water pressure up to 2,000 psi while petrol powered versions can provide higher water pressures.
High pressure pump: This essential pump draws water from a water supply or tank.
Jetting gun: This is a hand-operated device used to direct high pressure water streams at the surface intended to be cleaned.
Nozzle: A device with orifices through which high pressure water is discharged.
High pressure washers are available in various pressure capacities and sizes, and nozzles. Some feature hot or cold water streams and other nozzles allow combined water and detergent solutions for cleaning. Selecting the appropriate high pressure cleaner system for your needs is vital for its safe use and effective application.
