When it comes to choosing a high pressure washer at the time of purchase, there are several factors to consider. The features are many, but the first things to consider are the pressure of the outlet water and the volume of water delivered per unit of time.
One of the factors that determine the efficiency of the cleaner according to the work that needs to be done is the outlet pressure. This is measured in bar and is the power with which the water will shoot to the surface.
In general, the high pressure washers that have lower pressure 190 bar are ideal for light and medium-light duty, such as cleaning elements, outdoor furniture, cars, sidewalks, driveways, patios, fences, etc.
The high pressure cleaners, suitable for the heaviest jobs have an output pressure of over 200 bar and are good for a variety of jobs including cleaning of paths or larger areas such as roads, and for the preparation of surfaces for painting. There are also high pressure cleaners are suitable to work very hard, with a pressure of more than 230 bar.
In principle, a higher pressure provides more power to clean but be careful: some surfaces don't hold up the pressure too high. And' the case of glazed surfaces, in which the paint may be damaged.
In addition to the pressure at the outlet another factor to consider in buying a pressure washer is the flow rate.
The flow rate represents the volume of water provided from the machine, measured the liters per hour (l/h). A higher flow rate allows the rinse is more rapid in areas.
These two factors, pressure and flow rate, indicate the level of cleaning that ensures the pressure washer:
high levels of pressure and flow allow for a more thorough cleaning and better cleaning of hard-to-reach. But be careful: not all surfaces can withstand high pressure and use large volumes of water for minor works is a big waste.
Many models, to ensure greater flexibility in the use, have a pressure regulator.
Other specifications of pressure washers: what is the difference between a high-pressure cleaner on the other?
The pump: some pressure washers have a pump with 3 pistons that move with a system of connecting rods-crank. These are ideal for most heavy-duty and, in general, for professional use. Other models have a pump, the three pistons driven by a plate oscillating, which it defines axial pump, and are suitable for uses less intense.
The head, which can be for high or low pressure. Many models give you the possibility to select the mode.
The spray pattern: fan-shaped, straight or rotating, which combines the power of the spray with a circular motion), for high-and low-pressure adjustable.
The detergent tank: that can be embedded or external.
The thermal protection of the motor: in order to avoid the risk of overheating.
The possibility of adjustment of the pressure: which makes the cleaner suitable for a variety of jobs and surfaces, allowing the user to act with greater delicacy on the surfaces of the enamel.
Hot or cold water: to wash surfaces soiled with grease, and, in general, in which the dirt needs to be loose, using high-pressure cleaners hot water in which the water is heated thanks to a boiler with a burner with a spiral staircase generally driven by an electric motor independent.
The engine: electric or internal combustion
